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 1/1/49-1/1/52 are port channel members, and (P) indicates each is up and active. The uplink port channel can also be verified. Port channel 100 is up indicated with the (U) and ports 1/1/55 and 1/1/56 are active indicated with the (P).

The show vlan command is used to view interfaces assigned to each VLAN and whether the interfaces are access/untagged (A) or tagged (T). Port channel 100 is the uplink to the external switches and is tagged for the external management VLAN, 1811. 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.

The show ipv6 mld snooping interface vlan 3939 command is used to verify MLD snooping and querier that are enabled on VLAN 3939, shown in bold in the output below.
S5248F-Leaf1A# show ipv6 mld snooping interface vlan 3939
Vlan3939 is up, line protocol is up
MLD version is 2
MLD snooping is enabled on interface
MLD snooping query interval is 60 seconds
MLD snooping querier timeout is 130 seconds
MLD snooping last member query response interval is 1000 ms
MLD snooping max response time is 10 seconds
MLD snooping fast-leave is disabled on this interface
MLD snooping querier is enabled on this interface
Multicast snooping flood-restrict is enabled on this interface
The show lldp neighbors command is useful for identifying connected equipment. Interfaces 1/1/25-28 are connected to the Broadcom adapter in each of the VxRail 7.0 nodes, and 1/1/49-1/1/52 are connected to the other leaf.

If an entry is not shown for the jump box or laptop computer (port 1/1/9:1 above), it means the NIC on the remote system does not have LLDP enabled. This is not required and may be ignored for this solution.
