Use the CLI commands in this section to validate the leaf switch configuration.
show interface status
The show interface status | grep up
command is used to verify that the required interfaces are up, and that the links are established at the appropriate speeds.

show vlt
The show vlt 1
command validates the VLT configuration status when the VLTi Link Status is up. The role of one switch in the VLT pair is primary, and its peer switch is assigned the secondary role.

show port-channel summary
The show port-channel summary
command is used to view port channel numbers, interfaces used, and status. In SmartFabric OS10, the VLTi is automatically configured as a static LAG using port channel 1000. Ports 1/1/29 and 1/1/31 are port channel members, and (P) indicates each is up and active.
Port channel 1 is also created for interfaces that are connected to MX9116n FSEs. As shown below, the ports that are added in the port channel are ports 1/1/1, and 1/1/2.

show vlan
The show vlan
command is used to view interfaces that are assigned to each VLAN and whether the interfaces are access/untagged (A) or tagged (T). Port channel 1000 is the VLTi. VLAN ID 4094 is reserved as an internal control VLAN for the VLT domain, and it is not user configurable. VLANs 1611 to 1616 are also shown which are ESXi management, vMotion, vSAN, and VM network VLANs.

show lldp neighbors
The show lldp neighbors
command provides information about connected devices. In this case, ethernet1/1/1 and ethernet1/1/2 connect to the two MX9116n FSEs. The remaining links, ethernet1/1/29, and ethernet 1/1/31, represent the VLTi connection.
