Continuing with the show interface theme from yesterday, let's look at the show interfaces status command. I love this command. It's a quick way to view a summary of interface information on switch ports. Example:
SW1#show interfaces status
Port Name Status Vlan Duplex Speed Type
Gi0/0 connected 1 auto auto unknown
Gi0/1 connected 1 auto auto unknown
Gi0/2 connected 20 auto auto unknown
Gi0/3 connected 30 auto auto unknown
Gi1/0 connected 1 auto auto unknown
Gi1/1 Link to SW2 connected trunk auto auto unknown
Gi1/2 connected 1 auto auto unknown
Gi1/3 Link to R10 connected routed auto auto unknown
The output lists the interface name, the interface description (under Name), the status of the interface, the VLAN ID the interface is assigned to (if in access mode) or trunk port, the duplex, speed, and interface type settings. I ran the command on VIRL, so the duplex, speed, and interface type shows auto, auto, and unknown, respectively. Here's an example from a hardware switch:
3560#sh interfaces status
Port Name Status Vlan Duplex Speed Type
Fa0/1 connected trunk a-full a-100 10/100BaseTX
Fa0/2 connected trunk a-full a-100 10/100BaseTX
Fa0/3 connected trunk a-full a-100 10/100BaseTX
Fa0/4 notconnect 1 auto auto 10/100BaseTX
The show interfaces status command also accepts err-disabled and vlan parameters. The show interfaces status err-disabled command displays the ports in the error-disabled state. The show interfaces status vlan command limits the output of switch port information to the specified VLAN.
