4Enter the tag type for each port in the VLAN.

5Enter the VLAN name.

Bridge VLAN Define Example (9000 Layer 2)

This example shows a port-based VLAN that includes tagged front-panel ports and a tagged backplane port (port 21). These ports are tagged because they overlap with ports that belong to other VLANs:

■Because the front-panel ports are tagged, any attached devices must be IEEE 802.1Q enabled.

■Because the backplane port is tagged, the corresponding switch fabric module port must also be tagged in the VLAN definition on the switch fabric module. (You connect to the switch fabric module and define the VLAN to include the appropriate tagged switch fabric module port, based on the slot that contains the switching module.)
