Figure 8-4 Serial Port Adapters in the Catalyst 5509
You can identify interface ports by physically checking the port-adapter/interface port location on
the back of the router or 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 theCisco 7120 series routers are numberedas 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. Slots 2
and 4 are not used on the Cisco 7120 series routers. Slot 5 is the service module.
