The slotnum parameter is required on chassis devices.

Displaying a port dual-mode VLAN membership

The output of the show interfaces command lists dual-mode configuration and corresponding VLAN
numbers. The following shows an example output.

device# show interfaces ethernet 7

GigabitEthernet7 is down, line protocol is down

Port down for 2 days 1 hour 40 minutes 5 seconds

Hardware is GigabitEthernet, address is 0000.00a8.4706 (bia 0000.00a8.4706)

Configured speed auto, actual unknown, configured duplex fdx, actual unknown

Configured mdi mode AUTO, actual unknown

Member of 3 L2 VLANs, port is dual mode in Vlan 4

, port state is BLOCKING

Syntax: show interfaces ethernet [slotnum/]portnum [to [slotnum/]portnum [ethernet
[slotnum/]portnum...]]

The slotnum parameter is required on chassis devices.

NOTE
The port up/down time is required only for physical ports and not for loopback/ ve/ tunnel ports.

Displaying port default VLAN IDs (PVIDs)

The output of the show interfaces brief command lists the port default VLAN IDs (PVIDs) for each
port. PVIDs are displayed as follows:

• For untagged ports, the PVID is the VLAN ID number.
• For dual-mode ports, the PVID is the dual-mode VLAN ID number.
• For tagged ports without dual-mode, the PVID is always Not Applicable (NA).
