show interface status

Theshow interface status | grep upcommand is used to verify required interfaces are up,andlinksare establishedat their appropriate speeds. In this example, ports 1/1/1-1/1/3 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.

show port-channel summary

Theshowport-channel summarycommand is used toview portchannel numbers, interfaces used, and status. Port channel 1 (number may vary) is the L2 uplink. Port channels 96-97 (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.

showvirtual network

Theshow virtual networkcommand is used to view virtual networks, VLANs, and interfaces assigned to each VLAN. Port channel 1 (number may vary) is the L2 uplink if configured. Port channel 1000 is the VLTi. Interfaces 1/1/1-1/1/3 are connected to VxRail nodes. Interface 1/1/9:1, shown under VLAN 1811, is the jump host port.

Note:The jump host port was automatically moved from VLAN 4091 to VLAN 1811 during VxRail deployment.

showlldpneighbors

Theshowlldp neighborscommand is useful for identifying connected equipment. Interfaces 1/1/1-3 are connected to the Broadcom adapter in each VxRail node, 1/1/53-54 are connected to the external network, and 1/1/55-56 are connected to the spines. Interface 1/1/9:1 is connected to the jump host, and mgmt1/1/1 is connected to the OOB management switch.

Note:If an entry is not shown for the jump host, port 1/1/9:1 in the above example, the jump host may be connected to the other leaf switch or the NIC on the jump host does not have LLDP enabled. This is not required and may be ignored.

show ip interface brief

Run theshow ip interface briefcommand to verify connected interfaces are up, and IP addresses are configured correctly.

In the output below, interfaces 1/1/1-1/1/3 are connected to the VxRail nodes, 1/1/49-1/1/52 are the VLTi, and 1/1/53-1/1/54 are L3 uplinks to the external switches. 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.

Note:Unused interfaces have been removed from the output for brevity.

Codes: C - connected

S - static

B - BGP, IN - internal BGP, EX - external BGP

O - OSPF, IA - OSPF inter area, N1 - OSPF NSSA external type 1,

N2 - OSPF NSSA external type 2, E1 - OSPF external type 1,
