Spanning tree considerations
For VXLAN networks, the network must be loop free. SFS does not allow configuration of the same network on multiple uplinks to ensure
that no loops are created accidentally.
For Layer 3 VLAN networks, RPVST+ is enabled on the uplink interfaces by default. It is recommended not to change the spanning tree
type or to disable it.
Dynamic onboarding for integrated devices
SFS discovers and onboards the following vendor end-host devices based on specific custom originator TLVs in LLDP PDUs sent out
through the connected ports.
• iDRAC
• Isilon
• VxRail
• Trident
• VxFlex
When a new server interface is detected in an attached port, the new configuration is applied.
Statically onboarded server
• STP is disabled on the attached ports.
• The bonding can be auto or LACP.
• All types of networks can be attached to these ports.
Static onboarding for nonintegrated devices
SmartFabric services support onboarding server on assigned ports instead of LLDP based discovery mechanism. SFS extent the server
profile and server interface profile for you to provide onboarded interface.
• All existing bonding modes is supported on statically onboarded server.
• Wherever possible, STP is enabled on these ports. Since VXLAN does not support STP on access ports, this is not applicable for L3
Fabric. RPVST+ is enabled on Layer 3 VLAN networks. For the VXLAN type of network, no STP can be configured; 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.
Enable SmartFabric Services on the switches
To create a L3 network fabric in a leaf and spine topology, enable the SFS in all the switches. After you enable SFS, a network fabric is
created automatically with the default fabric settings.
To enable the SFS:
• Designate a role for the switch: Leaf or spine
• Configure VLT interfaces for the leaf switches.
To enable the SmartFabric Services in a switch from the OS10 CLI, use the smartfabric l3fabric enable command. For more
information, see smartfabric l3fabric enable. After you enable the SFS on the switches and set a role, the system prompts for confirmation
to reload and boots in the SFS mode. To apply the changes, confirm by typing Yes and the switch reloads in the SFS mode.
Spine:
OS10(config)# smartfabric l3fabric enable role SPINE
Reboot to change the personality? [yes/no]: yes
