When the uplink interfaces have been configured on the external switches and in the SFS UI, verify connectivity by using the switch CLI.
Show command output on External-A
Run the show ip interface brief command to verify that connected interfaces are up and that IP addresses are configured correctly. In the following output, interface 1/1/1 and port channel 1 connect to the DNS/NTP server. 1/1/51–1/1/52 are the links to the SFS leaf switches, and 1/1/49–1/1/50 are the VLTi links. VLAN 4094 and port channel 1000 are automatically configured for the VLTi.
