SFS fundamentals
This chapter provides information about the fundamentals of SFS including overview, supported topologies and platforms,
network fabric formation, and its supported solutions.
SFS overview
SFS is a SmartFabric OS10 feature that provides network fabric automation and API-based programming capabilities. SFS
has different personalities that can be integrated with systems including VxRail, PowerScale, generic PowerEdge servers,
PowerStore, storage, and MX servers. SFS integrated with these solution-specific deployments delivers autonomous fabric
deployment, expansion, and life cycle management.
SFS has two types: SFS for PowerEdge MX and SFS for leaf and spine. The following sections focus on concepts that are
related to SFS for leaf and spine:
SFS for leaf and spine is supported on S-series and Z-series Dell EMC PowerSwitches. See Supported platforms for a complete
list of supported platforms. SFS for leaf and spine has two personalities:
L2 single rack personality
NOTE: This personality is not available for deployments after OS10.5.0.5 release. All single rack and multirack deployments
from 10.5.0.5 release and later uses the L3 personality.
SFS deployments on OS10 releases from 10.4.1.4 to OS10.5.0.5 support only L2 single rack.
●Provide fabric automation for a single pair of leaf switches.
●SFS deployment is limited to a single rack and cannot be expanded to a multirack deployment.
NOTE: When you upgrade switches with this personality enabled, they operate in the L2 single rack personality only.
●SFS L2 single rack personality is enabled by running a Python script in the OS10 Linux shell. See Enable L2 personality for
more information.
L3 multi rack personality
All SFS deployments using OS10.5.0.5 and later releases support SFS L3 personality and the capabilities are as follows:
●Provides fabric automation for leaf and spine.
●Allows SFS deployment in a single rack and expand to multirack as required.
●Allows you to enable SFS using CLI, API, or GUI.
NOTE: In an MX-based deployment, the fabric is configured using OpenManage Enterprise-Modular (OME-M) UI, see Dell
EMC OpenManage Enterprise-Modular Editions User Guide available in PowerEdge MX Documentation.
See the Solutions Support Matrix for a complete list of solutions that can be onboarded onto the fabric.

SFS fundamentals 7
This guide covers the following SFS qualified solutions:
●SFS deployment with VxRail
●SFS deployment with PowerEdge MX
●SFS deployment with Isilon/PowerScale
SFS GUI
OS10 has support for SFS GUI to set up the initial SFS configurations in a L3 leaf and spine topology. You access the SFS GUI
using the latest version of the following browsers:
●Google Chrome
●Mozilla Firefox
●Microsoft Edge
For more information about SFS GUI, see Access fabric setup configuration.
Supported network topologies
Following are the supported network topologies for SFS L3 multirack deployment:
●One leaf switch pair without spine switch
●Multiple leaf switch pairs with a two or more spine switches
SFS supported platforms
SFS is supported on the selected S-series and Z-series PowerSwitches for leaf and spine deployments. The platform support
varies depending on the solutions such as VxRail, PowerScale, and so on. The supported platforms are listed in Supported
Switches section under respective solution chapters.
Creating a network fabric
When you enable SFS on the switches in leaf and spine architecture, a single network fabric is built with all the discovered
switches using industry-standard L2 and L3 protocols. SFS supports the following automation capabilities in a leaf and spine
topology:
●Elects one leaf switch from the fabric as the master switch.
●Creates the infrastructure VLANs on the nodes.
●Allocates all the necessary internal IP addresses for leaf and spine configurations.
●Autoconfigures necessary BGP for all the relevant leaf and spine switches.
●Enables leaf and spine for underlay and overlay.
●Provides workload orchestration of server discovery and binding server profiles to networks.
See Internal components and entities for more information about infrastructure networks and fabrics that are created by SFS.
Also, you can use SFS show commands to view and verify fabric-related configuration.
After the fabric is created, you can configure uplinks, jumphost, and onboard servers to the fabric using the SFS GUI.
Server discovery and onboarding
SFS discovers and onboards a server based on the LLDP from the server when connected to the fabric.
Onboarding a server involves creating a server profile and assigning the networks (VLANs) to a specific server NIC port
connected to the switch port.
You can onboard a server in the following ways:
●Dynamic onboarding
●Static onboarding
8SFS fundamentals
Dynamic server onboarding
When the servers are connected to the fabric, SFS discovers the servers automatically.
SFS discovers a host as known servers based on the specific custom originator TLVs in LLDPDUs sent through the connected
ports. Following are the list of known servers discovered by SFS :
●VxRail
NOTE: SFS discovers and onboards the VxRail server automatically.
●PowerStore X
●PowerStore T
When a known server is discovered on the server-facing port, SFS applies the server profile configuration. When a known server
is disconnected, the stale entry is removed from the LLDP neighbor table.
Dynamic discovery of unknown servers
With OS10.5.2.2 and later releases, SFS dynamically discovers unknown servers using the standard LLDPDUs sent out through
the connected ports. Unknown server is a host that does not send a valid originator in custom TLVs in LLDP frame. Upon
discovery, the client management network is configured by default.
NOTE: If the LLDP TLVs are advertised with both bridge and routing capabilities, SFS considers that the interface is
connected to a switch or router. Hence, the client management network is not configured on that interface.
For onboarding an unknown server, the Port-id TLV in LLDP packet is mandatory. SFS matches the Port-id TLV value in the
LLDP packet against the Interface field in the server interface profile to onboard the unknown server. After the server
interface profile is configured, the onboard criteria for unknown server is same as onboarding a known server.
●If both known and unknown LLDP neighbors exist on the same interface, SFS discovers these servers as known and
unknown servers. During onboarding, if the server profile matches with both the known and unknown discovered servers on
the same physical interface or with the same server interface profile, the order of onboarding is as follows:
○Known discovered server
○Unknown discovered server
If you offboard the known server, SFS checks for the unknown server and onboards it if available.
●If both known and unknown LLDP neighbors exist with the same port ID, SFS discovers both the known and unknown
servers. During the onboard process, the order of onboarding is as follows:
○Known discovered server
○Unknown discovered server
If you offboard the known server, SFS checks for the unknown server and onboards the server if available.
●If there is a static onboarding server profile that is configured on an interface where the known and unknown LLDP
neighbors exist, SFS discovers both the LLDP neighbors. During onboarding if there are conflicts on the physical interface or
server interface profiles, the priority order of onboarding is as follows:
○Static onboarding
○Known discovered server
○Unknown discovered server
If you offboard the statically onboarded server, SFS checks the known servers list first and then the unknown server list to
onboard the device based on the priority order.
Static server onboarding
SFS supports static onboarding of server on assigned ports instead of LLDP-based discovery. This option is used for onboarding
servers that are not discovered by SFS.
To statically onboard a server, you must assign an interface of the leaf switch to which the server is onboarded. See Onboard
nondiscovered server interfaces section in Onboard a Server for more information about static onboarding using GUI.
Configuration notes:
●STP is disabled on the server-connected ports.
SFS fundamentals 9
●The bonding can be static or LACP.
●All existing bonding modes are supported on a statically onboarded server.
●VXLAN does not support STP on access ports and it is not applicable for L3 Fabric. For the VXLAN type of network, you
cannot configure STP; the network topology must remain loop free.
●All existing network types are allowed to be onboarded on statically onboarded servers.
●Since onboarding is static, when server is moved there is no support for moving the configurations along with the server.
●The port-role for the statically onboarded server is EndHost or GenericEndHost.
●When the server profile or server interface profile is deleted, all the impacted interfaces are brought to default configuration.
Server profile and server interface profile
Server profile and server interface profiles are logical entities of SFS. You configure these entities when onboarding a server to
the fabric.
Server interface profile represents the server NIC ports that are connected to the leaf switches. For a server interface profile,
a server interface ID must be configured using the MAC address of the server NIC port. SFS uses the server interface ID to
identify the server NIC port and configure the required networks on the server NIC ports.
Server profile is a list of server interface profiles with a common bonding type. Supported bonding types are AutoDetect and
LACP. You can configure a server profile using SFS UI, see Server onboarding. To view the server profiles available on the SFS,
see Manage server profiles.
Fabric back up and restore
You can backup the SFS configuration to an external device, and restore the fabric to a good state using the backed-up
configuration during a failure or error.
The backup functionality allows you to backup all the user configuration to a text file in JSON format. The REST endpoints are
available that returns a text file containing all the user configuration that was done through the REST interfaces.
The restore functionality allows you to restore the fabric to a last known good configuration. The REST endpoint is available that
enables you to stream the backed-up configuration. The restore action wipes the data completely and restores the configuration
on the switches from the backup file. The restore functionality is followed by mastership switchover. For the successful restore
operation to occur, the restore activity should be applied to the same set of switches in the fabric. Also, the SFS personality
should be the same when the backup was performed.
The backup and restore endpoints are accessible only for the users with sysadmin role. The REST payload is encrypted using
the SSL protocol.
You can also restore the configuration for a fabric from SFS UI, see Restore.

10 SFS fundamentals
Setting up SFS
This chapter explains the workflow to setup SFS including initializing SFS and enabling it on leaf and spine switches.
Prerequisites
Ensure that the following are met before enabling SFS on the switches:
●Configure the Out-of-band (OOB) management configuration on the leaf switches. OOB management network enables
connections to the SFS GUI. Dell EMC PowerSwitch S3048-ON can function as an OOB management switch with the
OS10 factory default configuration. For more information about OOB management topology and connection details, see the
respective Solution Deployment Guides
●Verify the SmartFabric OS10 version on the switches and update them with recommended version listed in the Support
Matrix.
SFS configuration notes
This section lists important behaviors, considerations, and recommendations you must know before deploying SFS:
Recommendations
See Internal components and networks for more information about the SFS components and networks that are created by SFS.
Recommendations and notes regarding the SFS components are:
●Dell Technologies recommends that you do not change or disable the STP settings on switches in SmartFabric mode. Any
change to the STP settings results in reboot of all the switches in the fabric and disabling STP settings cause loops.
●Dell Technologies recommends using uplinks from a leaf pair as a best practice. Uplinks from leaf switches to external
switches can be L2 or L3. All uplinks from spine switches to external switches must be L3.
●Except for Isilon/PowerScale deployment, breakout feature is not supported on the leaf switches for the ICL (VLTi) or ISL
(leaf and spine) connections. Use the default speed cables of the leaf switch when creating the ISL or ICL connections in a
L3 fabric.
○ISL example—If the default speed on the leaf switch port is 100G and spine switch port is 400G, use 100G cable for ISL
connection. Since autobreakout feature is enabled on the spine switch, the port speed of the spine switch is set to 100G
automatically.
○ICL example—If the default speed of the leaf switches is 100G, use 100G cable for the ICL connection.
●Ensure that the leaf switches in the existing fabric are set as the Preferred Master before expanding the fabric to prevent
the configuration loss. Preferred Master flag is automatically set when you create an uplink for the leaf switches using SFS
GUI. Once a master is elected, it initiates all applications to automatically build the network fabric, and master virtual IP
address is advertised for applications to automatically discover the fabric through inband networks.
●If you want to breakout the ports to configure uplinks or jump hosts, ensure that the breakout ports are configured on the
switch before creating and configuring these entities. You can configure breakout ports using SFS GUI.
Default settings
●SFS creates VLANs from 4000 to 4094 for internal use. Do not use these VLANs for general use.
●SFS creates 172.16.0.0/16 and 172.30.0.0/16 networks for the leaf and spine network configuration.
●By default, autobreakout feature is enabled on the leaf switches in SmartFabric mode. Autobreakout works only on DAC and
AOC cables.
3
Setting up SFS 11
SFS behavior
SFS elects one switch from the fabric as a master switch and designates the remaining leaf switches as the backup switches.
In the event of a master failover, a new master is elected from the backup switches using the keepalive information. The
switches that are configured as Preferred Master have a higher priority to become the master switch. If none of the switches
are configured as the preferred master, any leaf switch can become the master.
When you expand the fabric, the newly added switches may come up and form a fabric among themselves, and elect a master
before they are connected to the existing fabric. When the new fabric merges with the existing fabric, SFS elects a new master
switch for the combined fabric. If one of the new leaf switches becomes the master, it may overwrite the configuration in the
existing fabric.
Spanning tree considerations
●To avoid loops, SFS does not allow you to configure the same network on multiple uplinks.
●SFS supports RPVST+ and MSTP. The default spanning tree mode in SFS is RPVST+. Once the fabric is created, you can
change the STP mode using SFS GUI, see Edit default settings.
NOTE: When you change the mode using GUI, the whole fabric goes through a reboot and the new mode is set to
MSTP. The reboot action impacts the traffic flow in the cluster.
●By default, RPVST+ is enabled on the uplink interfaces for L3 VLAN networks. When RPVST+ is enabled on the uplink, the
total number of Port VLANs (PV) supported is 400.
Configure SFS
By default, PowerSwitches boot in Full Switch mode when you power them up with SmartFabric OS10. This information explains
how to setup a fabric.
1. Enable SFS and set roles on the switches.
2. Connect to SFS GUI and complete the relevant fabric configurations to setup the fabric. See SFS GUI for more information
regarding login procedure and fabric configurations.
For SFS with Isilon/PowerScale deployment, you only have to enable SFS with roles on all the switches using CLI. All other SFS
initial deployment operations using UI are not required. For more information regarding PowerScale deployments, see the related
documents available in PowerScale Info Hubs.
Enable SFS on PowerSwitches
You can enable SFS on PowerSwitches through CLI, GUI, or REST API from OS10.5.0.5 and later versions. This option is
applicable only for SFS L3 leaf and spine personality.
After you enable SFS on all the switches in a leaf and spine deployment, a network fabric is created automatically with the
default fabric settings. See Internal fabric component and networks for more information about the default settings.
Enable SFS using CLI
To enable SFS on a switch using CLI, run the smartfabric l3fabric enable command and set a role. For more
information, see smartfabric l3fabric enable.
After you enable SFS on the switches and set a role, the system prompts for a confirmation to reload and boots in the
SmartFabric mode. Enter Yes to continue. In SmartFabric mode, the CLI is restricted to global switch management features and
monitoring. Using this command, enable SFS on all the switches with the corresponding role to create a fabric.
The following example shows how you can enable SFS on switches and set roles:
Spine:
OS10(config)# smartfabric l3fabric enable role SPINE
Reboot to change the personality? [yes/no]: yes
12 Setting up SFS
Leaf:
In SFS, the two leaf switches are automatically configured as a VLT pair.
OS10(config)# smartfabric l3fabric enable role LEAF vlti ethernet 1/1/4-1/1/5
Reboot to change the personality? [yes/no]: yes
In the above example, the Ethernet interfaces 1/1/4 and 1/1/5 are the VLTi interfaces.
In Isilon or PowerScale back-end deployments, when enabling SFS in a leaf and spine topology, no VLTi configuration is required
for the leaf switch. To set the leaf role for a switch, use the smartfabric l3fabric enable role LEAF command
without the VLTi parameters.
Enable SFS using RESTCONF API
You can enable SFS on OS10 switches using the RESTCONF API. For more information regarding general RESTCONF API
operations, see Dell EMC SmartFabric OS10 User Guide.
Description Enables SFS on the switches with leaf and spine roles.

Example—Usage of curl command on a linux server is as shown:
Enable SmartFabric Services L2 personality using script
In SFS L2 personality, you can enable SFS only using API. All deployments from SmartFabric OS10.4.1.4 to OS10.5.0.x version
support only the single rack network fabric.
NOTE: The L2 personality is not available for new deployments after 10.5.0.5 release.
A python script is used to enable SFS. For more information about L2 personality commands and information, see VMware
Integration for VxRail Fabric Automation SmartFabric User Guide, Release 1.1 available in OMNI Documentation page.
Enable SFS using GUI
To enable SFS using the GUI, following the instructions:
1. Enable RESTCONF API on the switch using the OS10 CLI.
To enable RESTCONF API, use rest api restconf command in CONFIGURATION mode. See Dell EMC SmartFabric
OS10 User Guide for more information about RESTCONF API.
2. Open a browser session, go to https://
switch-mgmt-ip-address
.
3. Log in to a switch using the credentials that are created to access an OS10 switch. The default username and password is
admin.
4. Enable SFS on the switch using the Edit option that appears in the upper-right side of the page.
5. Enter the role of the switch and click OK to enable SFS.
14 Setting up SFS
Spine:
Leaf:
After you enable SFS on a switch, the system reloads to apply the configuration.
6. Repeat the steps 1 to 4 on all the remaining switches to enable SFS and set role. All switches reload and forms a fabric.
Verify the switch operating mode
To verify that the switches are in SmartFabric mode, run the show switch-operating-mode command on each switch.
OS10# show switch-operating-mode
Switch-Operating-Mode : SmartFabric Mode
For more information regarding the CLI, see the show switch-operating-mode command.
Setting up SFS 15
Disable SFS using CLI
To delete the existing switch configuration and go back to Full Switch mode, run the no smartfabric l3fabric command

Appendix
This chapter covers additional information that can support you with the fabric configuration tasks.
Internal fabric components and networks
SFS automatically creates the following components and networks:
Internal SFS components
SFS creates a VLT fabric automatically in the leaf and spine environment. VLT fabric is autoassigned with a fabric-ID, a
universally unique identifier (UUID). When a VLT fabric is created, the management IP addresses of the VLT peers are used
automatically to set up the VLT backup link. If the management IP address of the peers is changed after the fabric is created,
the VLT backup link is updated automatically.
SFS creates a network fabric with the leaf and spine switches automatically. The network fabric is autoassigned with a
fabric-ID, a name, and description. The fabric name and description are automatically assigned, but can be changed through the
SFS GUI. For more information, see Update fabric name and description.
Fabric links create a connection between the switches in a network fabric. ISL is a link formed between a leaf and spine switch.
All parallel links with same connectivity are grouped to form a LAG interface. ICL or VLT interconnect (VLTi) is a link formed
between the two leaf switches in a same rack.
Internal virtual networks
The internal virtual networks created by SFS are:
VLAN 4000 for
SFS cluster
control
SFS automatically configures VLAN 4000 on all the switches that are discovered in a fabric, and uses the
network for all internal fabric operations. When a leaf or spine switch is discovered, the ICL or ISL ports
are automatically added as tagged members.
VLAN 4001
to 4079 for
leaf and spine
connections
SFS automatically configures the leaf and spine network using eBGP as the underlay routing protocol.
SFS uses the reserved VLAN range from 4001 to 4079 with automatic IP addressing to set up the peer
connections. When SFS detects an ISL connection on either a leaf or spine switch, it assigns the ISL to
the untagged member of this VLAN. IP address from reserved range is used for this VLAN, and an eBGP
session is started on the VLAN interface.
VLAN 4080 for
Global untagged
VXLAN
SFS automatically configures VXLAN overlay networks with EVPN to extend networks between racks in
a multirack deployment. VLAN 4080 with automatic IP addresses from the reserved range is used for ICL
links. VXLAN requires one VLAN to be assigned globally for untagged port-scoped VLAN (Port, VLAN)
pairs.
VLAN 4089—
OS10 internal use
In SmartFabric mode, VLAN 4089 is the default VLAN and is reserved for OS10 internal use.
VLAN 4090—
iBGP peering
between leaf
switches
SFS automatically configures iBGP peering between a pair of leaf switches directly connected over ICL
links. VLAN 4090 is created automatically with IP addresses from reserved range for enabling iBGP
sessions between the VLT peer switches.
VLAN 4094—VLT
control VLAN
SFS automatically creates VLAN 4094 on all leaf switches. This VLAN is used for all VLT control traffic
between two VLT peer switches and is added on the VLT ICL ports on leaf switches.
VLAN 4091—
Default client
management
network
SFS automatically configures an overlay network that is called a client_Management_Network.
When a device is automatically onboarded on to the network fabric, the device uses the VLAN mapped to
this overlay network. This network is a native VLAN unless there is a policy specifying a different native
VLAN. VLAN 4091 is used as the default client management VLAN for the VXLAN network.

56 Appendix
NOTE: You can change this VLAN to a specified VLAN through SFS GUI.
VLAN 3939—
Default client
control network
SFS configures a second overlay network that is called Client_Control_Network for SFS-integrated
solutions. When a device such as VxRail is discovered, it is automatically added as a tagged
member of this network. SFS enables master advertisement and fabric discovery by integrated
solutions. The SFS master virtual IP address for VXLAN network is advertised. The VIP address
fde1:53ba:e9a0:cccc:0:5eff:fe00:1100 is fixed and not user configurable.
VLAN 3939 is used as the default client control VLAN for this VXLAN network for SFS-integrated
solutions including VxRail and PowerScale solutions. Although you can change the VLAN associated with
the default client management and control networks, Dell Technologies recommends not to change the
VLANs for VxRail deployments.
NOTE: For more information about other internal general networks created by SFS, see Networks.
To check the networks that are created in SFS-integrated deployment, use show virtual-network command. Following is
the example output :

Reserved networks
SFS uses the 172.16.0.0/16 and 172.30.0.0/16 networks internally for the leaf and spine network configuration. If these networks
conflict with any networks in the existing deployment, change the default networks using the instructions that are provided in
Edit Default Fabric Settings.
MSTP Support on L3 personality
The default spanning tree mode in SFS is RPVST+. On Dell EMC PowerSwitches in SFS mode, RPVST+ is enabled globally and
automatically configured.
In L3 personality, SFS is enabled on:
●SFS cluster control VLAN (VLAN 4000). The spine switches are configured to take over the STP root role.
●All user created VLANs.
In L3 personality, SFS is disabled on:
●All inter leaf-spine VLANs and leaf-leaf VLANs (4001-4091).
●All server facing ports.
NOTE: Do not modify STP settings on switches in SFS L3 personality.
If you must interoperate switches that are controlled by SFS to external switches which are running RSTP or MSTP, SFS has an
API to change the global fabric STP mode to MSTP. SFS creates 2 reserved MSTIs:
●MST with instance id 63: Cluster control VLAN 4000 is part of this instance. Spine switches are configured to take over as
STP root for this MSTI.
Appendix 57
●MST with instance id 62: All the SFS reserved VLANs (4001-4091) are part of this configuration. On this MSTI, spanning tree
is disabled.
●All user created VLANs are part of CST (default MST instance), which interoperates with RSTP. STP is enabled for this
MSTI.
You can change the mode to MSTP once the fabric is created. When you change the mode, the whole fabric goes through a
reboot cycle and the new mode is set to MSTP.
NOTE: Changing the STP mode impact the traffic flow in the cluster.
When the mode is changed, MSTI is created and VLANS are assigned to the MSTI. The CST is configured with STP priority such
that SFS-controlled switches have lower priority to become a root bridge.
There is no change on existing STP behavior for SFS-controlled entities because of this change. All other STP behaviors such as
disabling STP on server facing ports still holds good.
You can enable MSTP or revert to RPVST using the Edit Default Fabric Settings option available in the SFS UI. Select STP
Mode as MST or Rapid PVST For more information, see Edit Default Fabric Settings.
NOTE: The default spanning-tree priority value that is configured on a SFS-enabled switch for VLANs or instance 0 is:
default priority for RPVST is 32769 and instance 0 priority for MSTP is 61440.
Networks
This section describes the following type of networks that you can create and associate these networks with the entities
present in a fabric:
●General purpose networks
●VXLAN networks
●L3 VLAN networks
●L3 Routed networks
●Multirack L3 VLAN network
NOTE: You cannot configure this network using SFS GUI. This network template is applicable for NSX-T deployment
and you can configure this network using OMNI UI. For more information about this network type, see OpenManage
Network Integration for SmartFabric Services User Guide, Release 2.0.
You can create these networks using SFS GUI and then associated these networks with servers profiles, uplinks, or interfaces
for traffic flow. For more information, see Create a network.
General purpose networks
General purpose networks can be categorized as L2 VLAN networks in SFS L2 personality and L2 VXLAN networks in SFS L3
personality. In L3 personality, when you create a general purpose network, SFS automatically creates a virtual network (VXLAN)
corresponding to a VLAN network. This virtual network has one-to-one mapping with the network, for each VLAN there exists
a virtual network with VNI same as the VLAN ID. If you delete a VLAN network, it automatically deletes the associated VXLAN
network.
For example, if you create a general purpose network with VLAN ID 50, SFS creates a VLAN 50 and associated VXLAN network
with VNI 50.
VXLAN networks
VXLAN network extends L2 connectivity over an underlay L3 connected network. Association of VXLAN network to interface
creates a binding and associates this interface to VXLAN bridge. L3 VXLAN network supports asymmetric-IRB. Create a virtual
network template and a network template, and associate the virtual network template to network template.
●The virtual network template defines the VNET-ID.
●Network template defines the VLAN ID.
L3 VXLAN network is a VXLAN type of network that contains a list of IP addresses and an anycast IP address. Optionally,
you can specify DHCP relay addresses. L3 VXLAN network can be configured over a leaf switch. L3 VXLAN network can be
attached to an uplink. Each VLTi uplink interface contains an IP address that is allocated from the list of IP addresses that are
configured on the L3 VXLAN network.
L3 VLAN network
L3 VLAN network is used for L3 VLAN underlay. Specify:
●VLAN ID
58 Appendix
●Pair of IP addresses to be assigned to the VLT pair
●VRRP gateway IP address for VIP
L3 VLAN network contains a list of IP addresses and a gateway IP address. Optionally, you can specify DHCP relay addresses.
You can configure and attach a L3 VLAN network to an uplink. Each VLTi uplink interface contains an IP address that is
allocated from the list of IP addresses that are configured on the L3 VLAN network.
L3 Routed network
L3 routed network is used to assign IP address on a single interface. L3 routed network contains a list of IP addresses and a
gateway IP address. Optionally, you can specify DHCP relay addresses. L3 routed network can be configured on a leaf or a spine
switch. L3 routed network can be attached to an uplink. Each uplink interface contains an IP address that is allocated from the
list of IP addresses that are configured on the L3 routed network. An LACP port channel cannot be the remote end for these
uplinks. If gateway IP address is specified, then VRRP is enabled and the switches configure this IP address as the gateway IP
address. Attach this network to any uplink that has a single interface. This network can only be attached to a single entity.
Multirack L3 VLAN network
Multirack L3 VLAN network is a template that contains rack-specific IP configurations for a L3 VLAN. You can configure IPv4
attributes for each rack in an NSX-T deployment consisting of multirack leaf and spine topology. A rack holds a pair of switches
that are configured with VLT. The rack identifier is the same as the fabric ID. A rack containing a single switch without VLT does
not support multirack L3 VLAN network.
In an NSX-T topology that is connected to an SFS cluster, you can create a multi rack L3 VLAN network. Specify the network
identifier, L3 VLAN ID, and list of rack-specific IPv4 configurations for this network. Attach the created network as untagged or
tagged on any uplink or server interface of the rack. After you attach the network, SFS automatically creates a L3 VLAN and
applies the rack-specific IP configurations to the respective rack within the topology. You can modify the IPv4 configuration for
a specific rack in the multi rack L3 VLAN network.
NOTE: For faster traffic convergence, Dell Technologies recommends setting the BGP keepalive timer to 1 second and
hold-time to 3 seconds on the NSX-T tier-0 node.
Uplinks
This information explains the types of uplinks that you can create in a fabric.
L2 uplinks
You can configure L2 uplinks only on the leaf switches in a fabric. L2 uplinks are a set of user-selected ports that belong to same
VLT leaf switches in which the L2 network is applied. The L2 uplink from the leaf switches is either an LACP or a static LAG.
SFS creates a VLT LAG for connected ports. If the ports are from a single device, the VLT LAG is a single armed VLT LAG. In
case these ports exist on multiple switches, a VLT or LAG is formed across these ports. This LAG can be made as an access
point for a VXLAN L2 network.
L3 uplinks
You can configure L3 uplinks on a leaf or spine switch. SFS supports L3 routed or L3 VLAN uplinks.
With L3 routed uplinks, point-to-point links are required between the switches with L3 uplinks and the external switches. With
L3 VLAN, all uplinks are in a LAG, and an IP address is assigned to the VLAN containing the LAG. Point-to-point IP networks
and addresses must be planned for each physical link in the L3 uplink. Each leaf switch in the fabric needs an IP address on the
external Management VLAN, and an anycast gateway address on the same VLAN. The virtual router or anycast gateway address
is shared by all leaf switches in the fabric.
Routing profiles
SFS supports eBGP and static routing profiles.
Static route profile—A static route profile is a routing template that contains a network prefix and the next hop IP address.
During uplink configuration, you can associate this profile to the uplinks created on one or more switches in the fabric. When this
profile is created, a route with the specified prefix and next hop IP address is configured on the switch.
Appendix 59
eBGP peer routing profile—An eBGP peer routing profile is a routing template that contains BGP remote addresses and
the remote AS number. A remote address can be an interface address or a loopback address. During uplink creation, you can
associate this policy to uplink created on one or more switches in a fabric. When this policy is created, a BGP session is
configured on the switch.
Uplink bonding options
Following are the uplink bonding types supported:
●LACP
●Static bonding
LACP
In LACP uplink bonding, SFS configure the LACP LAG for the uplink using the LACP PDUs received from the remote device.
Networks that are attached to the uplink are associated with the LACP LAG that is created.
Static bonding
In static bonding, SFS configures a static LAG for the uplink and the networks that are attached on the uplink are associated
with the LAG that is created.
