VLAN membership
In the navigation pane, the first four icons represent the following types of VLAN memberships:
|
Unassigned
|
A VLAN that contain ports removed from all port-based VLANs. If no devices in the network contain unassigned ports, a table does not open in the contents pane.
|
Tagging
|
VLANs with one or more ports with tagging enabled (user-defined). If a tagged frame is received on a tagged port, with a VLAN ID specified in the tag, the switch directs it to that VLAN, if it is present. Tagged ports can belong to multiple VLANs and multiple spanning tree groups.
|
Isolated Routing Port (IRP)
|
VLANs that route IP packets to a single device in a network.
Note: IRPs are applicable only to the Passport 1000 Series switch.
|
Bridge Routing (brouter ports)
|
Single port VLANs that can route IP packets as well as bridge all nonroutable traffic. The routing interface is not subjected to the Spanning Tree Protocol.
Note: Bridge routing, or brouter ports, are applicable to the Passport 1000 Series switch and the Passport 8600 modules only.
