Identifying Port Adapter Slot and T3 Interface Port Numbers

Figure 8-4 PA-T3 Serial Port Adapter in the Catalyst 5509

You can identify interface ports by physically checking the port-adapter/interface port location by using show commands to display information about a speciﬁc interface or all interfaces in the router.

Cisco 7100 Series Ports

In the Cisco 7100 series routers, the slot number is the location in the chassis where the interface resides and the port number is the physical port. Interfaces in the Cisco IOS software are identiﬁed by a type, slot number, and port number. For example, serial 3/1 indicates port 1 on the serial port adapter in slot 3.

Slots in the Cisco 7120 series routers are numbered as shown in Figure 8-5. The ﬁxed LAN interface is slot 0, the ﬁxed WAN interface is slot 1, and the modular port adapter interface is slot 3. In the Cisco 7120 series routers, slots 2 and 4 are not used. Slot 5 is the service module.
