This section provides a list of the most common commands and their output for the examples used in this guide. These examples are from the final topology with two VxRail clusters deployed, as shown in the SmartFabric topology with connections to VxRail nodes and external network figure.
General commands
show version
Leaf and spine switches must be running a supported version of SmartFabric OS10. Run the show version command to check the operating system version. SmartFabric OS10 is available on Dell Digital Locker (account required).

The show interface status | grep up command is used to verify required interfaces are up, and links are established at their appropriate speeds. In this example, ports 1/1/1-1/1/4 are VxRail nodes, port 1/1/9:1 is a jump host, ports 1/1/49-1/1/52 are the VLTi, ports 1/1/53-1/1/54 are uplinks to the external network, and ports 1/1/55-1/1/56 are uplinks to the spines.

The show port-channel summary command is used to view port channel numbers, interfaces used, and status. Port channel 1 (number may vary) is the L2 uplink to the external network, if used. Port channels 96 through 97 (numbers may vary) are automatically created spine uplinks. The VLTi is automatically configured as a static LAG using port channel 1000. Ports 1/1/53 and 1/1/54 are port channel members, and (P) indicates each is up and active.

The show virtual network command is used to view virtual networks, VLANs, and interfaces assigned to each VLAN. Port channel 1 (number may vary) is the L2 uplink to the external network if configured. Port channel 1000 is the VLTi. Interfaces 1/1/1-1/1/3 are connected to the VxRail nodes in the first cluster. Interface 1/1/4 is connected to the VxRail node in the second cluster. Interface 1/1/9:1, shown under VLAN 1811, is the jump host port.

The show lldp neighbors command is useful for identifying connected equipment. Interfaces 1/1/1-4 are connected to the VxRail nodes, and Interface 1/1/9:1 is connected to the jump host. Interfaces 1/1/53-54 are connected to the external network, and 1/1/55-56 are connected to the spines. Mgmt1/1/1 is connected to the OOB management switch.

Run the show ip interface brief command to verify connected interfaces are up, and IP addresses are configured correctly.
In the output below, interfaces 1/1/1-1/1/4 are connected to the VxRail nodes, 1/1/49-1/1/52 are the VLTi, 1/1/53-1/1/54 are L3 uplinks to the external switches, and 1/1/55-1/1/56 are connections to the Spine switches. IP addresses assigned to VLANs 4000-4094 and Loopback interfaces are for SFS internal use. The remaining IP addresses shown are configured in the steps in this guide. VLAN 4090, Loopback 1, and Loopback 2 are automatically configured by SFS. VLAN 4090 is used for iBGP, Loopback 1 is the router ID, and Loopback 2 is the VTEP IP address.
