The commands in this section are used to assign or remove ports on the egress list of a particular VLAN. This determines which ports will be eligible to transmit frames for a particular VLAN. For example, ports 1, 5, 9, 8 could be assigned to transmit frames belonging to VLAN 5 (VLAN ID=5).
The port egress type for all ports defaults to tagging transmitted frames, but can be changed to forbidden or untagged. In general, VLANs have no egress (except for VLAN 1) until they are configured by static administration, or through dynamic mechanisms (such as GVRP, policy classification, or Extreme Networks dynamic egress).
Setting a port to forbidden prevents it from participating in the specified VLAN and ensures that any dynamic requests (either through GVRP or dynamic egress) for the port to join the VLAN will be ignored. Setting a port to untagged allows it to transmit frames without a tag header. This setting is usually used to configure a port connected to an end user device.
The default VLAN defaults its egress to untagged for all ports.
