You can identify interface ports by physically checking the slot/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.

Catalyst RSM/VIP2 Ports

In the Catalyst RSM/VIP2, each port adapter address is composed of a two-part number in the format port adapter number/interface port number, as follows:

•The first number identifies the physical port adapter slot on the Catalyst RSM/VIP2, and is either 0 or 1.

•The second number identifies the interface port on each E3 serial port adapter, which is always numbered as interface 0 for the one-port PA-E3 and 0 or 1 for the two-port PA-2E3.

Figure 8-4 shows the port adapters on a Catalyst RSM/VIP2 installed in a Catalyst 5509 switch. The first port adapter slot number is always 0. The second port adapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.

For example, the serial port on a one-port PA-E3 in the first port adapter slot is numbered 0/0. (See Figure 8-4.) If the PA-E3 is in port adapter slot 1, this same port is numbered 1/0. The serial ports on a two-port PA-2E3 in the first port adapter slot are numbered 0/0 and 0/1.

Port adapters can occupy either port adapter slot; there are no restrictions.
