Identifying Port Adapter Slot and PA-4T+ Interface Port Numbers

VIP2 Ports

In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 8-3.) This address is composed of a three-part number in the format interface processor slot number/port adapter number/interface port number.

Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and 13-slot Cisco 7513 are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering.

The first number identifies the interface processor slot in which the VIP2 is installed.

The second number identifies the port adapter slot on the VIP2, and is either 0 or 1.

•The third number identifies the interface ports on each PA-4T+, which are always numbered in sequence as interface 0 through 3.

Interface ports on a PA-4T+ that is installed in a VIP2 maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP2 to a different slot, the first number in the address changes to reflect the new slot number.

Figure 8-3 shows some of the port adapter slot and interface ports of a sample Cisco 7505 router. The interface port addresses for the installed PA-4T+ are 3/1/0 through 3/1/3 (interface processor slot 3, port adapter slot 1, and interface ports 0 through 3). If the PA-4T+ was in port adapter slot 0, these same interface ports would be numbered 3/0/0 through 3/0/3.

Note If you remove the VIP2 (shown in Figure 8-3) from interface processor slot 3 and install it in interface processor slot 2, the addresses of those same PA-4T+ ports become 2/1/0 through 2/1/3.

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.
