Once the uplink interfaces have been configured on the external switches and in the SFS UI, additional validation is done by using the switch CLI.
Show command output on External-A
Run the show vlan command to verify that ports are correctly assigned to the External Management VLAN. Port channel 100 connects to the SFS leaf switches and is a tagged member of the same VLAN configured on the SmartFabric uplinks (VLAN 1811). The DNS/NTP server is connected on port channel 1, which is an access member of VLAN 1811 in the following example:
External-A# show vlan
Codes: * - Default VLAN, M - Management VLAN, R - Remote Port Mirroring VLANs,
@ - Attached to Virtual Network, P - Primary, C - Community, I - Isolated
Q: A - Access (Untagged), T - Tagged

1815 Active VM Network B T Po100,1000
1820 Active Storage T Po100,1000
4094 Active T Po1000
The show port channel summary command confirms that port channel 100 connected to the leaf switches is up and active. Port channel 1000 is the VLTi, and port channel 1 is connected to the DNS/NTP server.

With SFS, port channel numbers are automatically assigned as they are created. Port channel 2 is the uplink connected to the external switches and is up and active. Port channel 1000 is reserved for the VLTi.

The L2 uplink, port channel 1 in this example, is added as a tagged member of VLAN 1811. To verify, use the show virtual-network command as follows:
