Cisco Systems PA-T3 manual Catalyst RSM/VIP2 Ports, 3 Serial Port Number Example-Cisco 7505 Shown

Catalyst RSM/VIP2 Ports

For example, the serial port on a one-port PA-T3 serial port adapter in the first port adapter slot in chassis slot 3, is numbered 3/0/0. (See Figure 8-3.) If the PA-T3 serial port adapter is in port adapter slot 1, this same port is numbered 3/1/0. The serial ports on a two-port PA-T3 serial port adapter in the first port adapter slot in chassis slot 3 are numbered 3/0/0 and 3/0/1.

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

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

This section describes how to identify the port adapter and T3 interface port numbers on the Catalyst RSM/VIP2.

In the Catalyst RSM/VIP2, physical port addresses specify the actual physical location of each interface port. Each address is composed of a two-part number in the format port adapter/interface port, 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 PA-T3 serial port adapter, which is always numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for the two-port PA-T3 serial port adapter.

Figure 8-4 shows the port adapter slots and interface ports of a sample Catalyst 5509 switch. On the Catalyst RSM/VIP2, 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-T3 serial port adapter in the first port adapter slot is numbered 0/0. (See Figure 8-4.) If the PA-T3 serial port adapter is in port adapter slot 1, this same port is numbered 1/0. The serial ports on a two-port PA-T3 serial port adapter 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.
