Viewing the VLAN Configuration on a 1900 Series
Now that we have created the VLANs we want, we can use the show vlan command to see the configured
VLANs. Notice that all unconfigured ports on the switch are in VLAN 1. The command is used from the
Privileged mode prompt, as follows:
1912#show vlan
The results are shown here:
VLAN Name Status Ports

1 default Enabled 1, 3, 6−12, AUI, A, B
