aggregate-link identifier
Specifies an aggregate-link interface
composite-link identifier
Specifies a composite link interface.
ethernet 0
Specifies the single ethernet interface.
gbe bay/slot/port

Description: A passive interface in IS-IS is one which does not send or receive IS-IS routing traffic. The network for the interface is still included in LSPs generated by the router.
Use the passive-interface interface-identifier command to enable passive interface behavior on the specified interface.
Use the no passive-interface interface-identifier command to disable passive interface behavior on the specified interface.
Factory Default: No passive interfaces configured.
Command Mode: Router configuration.
Example 1: In the following example:
- The router isis command enables IS-IS on the router, specifies an IS-IS instance, and changes the command mode to Router configuration,
- The net network-entity-title command configures a NET,
- The passive-interface pos n/n/n command suppresses IS-IS routing updates on POS interface 1/5/1,
- The show running-config isis command displays the setting:
router(config)#router isis net1
router(config-router)#net 49.0001.0000.0000.0020.00
router(config-router)#passive-interface pos 1/5/1
router(config-router)#end
router#show run isis
