Assigning Port VLAN IDs (PVIDs) and Ingress Filtering
Purpose
To assign default VLAN IDs to untagged frames on one or more ports, to configure VLAN ingress
filtering and constraints, and to set the frame discard mode.
Commands

Use this command to display port VLAN identifier (PVID) information. PVID determines the
VLAN to which all untagged frames received on one or more ports will be classified.

Example
This example shows how to display PVIDs assigned to ge.2.1 through 6. In this case, untagged
frames received on these ports will be classified to VLAN 1:
C3(su)->show port vlan ge.2.1-6
ge.2.1 is set to 1
ge.2.2 is set to 1
ge.2.3 is set to 1
ge.2.4 is set to 1
