be enabled or disabled on an access port.

■
tagged, except for one port that can be untagged.
PVID — Assigns a VLAN ID to untagged packets. The possible values

■
possible field values are:

■
the port.
Ingress Filtering— Indicates whether ingress filtering is enabled on
■
the port. The possible field values are:
