58Appendix A IfIndexes and Interface Identification

Hard-Coded IfIndexes

The following IfIndex numbers are hard-coded, representing the interfaces that are initially present in the Passport 4460.

IfIndex	Description

1	Logical Ethernet interface for routed LAN traffic
2	Virtual port for WAN traffic
3	Logical Ethernet interface for bridged LAN traffic
4	Virtual port for network management traffic

Reserved IfIndexes and Ranges

The Passport 4460 also reserves IfIndexes for available ports on the base module and expansion data modules. By reserving these IfIndexes, the Passport 4460 guarantees that a specific port always uses the same IfIndex. For instance, Port 1 always uses IfIndex 150 to refer to the physical interface.

The following table lists IfIndexes that are reserved for use by the ports located on the base module.

Port Number	IfIndex - Physical Port	IfIndex - Connector IfIndex - Service

1	150	151	152
2	153	154	155
3	156	157	158

There are three reserved IfIndexes associated with each port. For Port 1, IfIndex 150 refers to the physical port interface, 151 refers to the connector interface, and 152 refers to the frame relay service.
