Incorrect Port VLAN Identifier (PVID)
Port VLAN identifier (PVID) is a classification mechanism that associates a port with a specific
VLAN. For example, a port with a PVID of 3 (PVID=3) assigns all untagged frames received
on this port to VLAN 3.
An issue can occur where clients cannot communicate to critical servers when their ports are
put in wrong VLAN. If the server is defined as a port based VLAN, with a VLAN ID of 3 and the
PVID of the port is 2, then loss of communication can occur
. This can be verified by checking
that the PVID of the ports match the VLAN setting. One way to avoid this problem is to set
VLAN configuration control to autoPVID.
For examples that show how to check the PVID of ports, and how to make PVID corrections,
