PVID

By default, VLAN 1 is the PVID for all ports. configure the PVID for a port as required.
When configuring the PVID on a port, use the following guidelines:
An access port can join only one VLAN. The VLAN to which the access port belongs is the PVID of

the port. The PVID of the access port changes along with the VLAN to which the port belongs.
 A trunk or hybrid port can join multiple VLANs. configure a PVID for the port.
 use a nonexistent VLAN as the PVID for a hybrid or trunk port but not for an access port. After you
use the undo vlan command to remove the VLAN that an access port resides in, the PVID of the port
changes to VLAN 1. The removal of the VLAN specified as the PVID of a trunk or hybrid port,
however, does not affect the PVID setting on the port.
HP recommends setting the same PVID ID for local and remote ports.
Make sure that a port is assigned to its PVID. Otherwise, when the port receives frames tagged with the
PVID or untagged frames (including protocol packets such as MSTP BPDUs), the port filters out these
frames.
The following table shows how ports of different link types handle frames:
Port type

Access links are required
Trunk links are reuqired
Hybrid links are required
