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.)
