Port membership

In the navigation pane, the top four icons represent the following types of port memberships:

• Unassigned
• Tagging
• Isolated Routing Port (IRP)
• Bridge Routing (brouter ports)

The table below describes the port membership types.

Icon	Port type	Description
	Unassigned	Port that do not belong to any STG. If no devices in the network contain unassigned ports, a table does not open in the contents pane.
	Tagging	Port that has tagging enabled and can belong to multiple STGs. 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.
	Isolated Routing Port (IRP)	Port that can only route IP packets and does not belong to any STG or VLAN. Note: IRPs are applicable only to the Passport 1000 Series switch.
	Bridge Routing (brouter ports)	Port 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 ports, or brouter ports, are available only on the Passport 1000 Series switch and the Passport 8600 switch.
