Cisco 7200 Series and the 4R Port Adapter

After you verify that the new 4R port adapter is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you will need, such as the following:

•Protocols you plan to route on each new interface

•Internet protocol (IP) addresses if you plan to configure the interfaces for IP routing

•Whether the new interfaces will use bridging

Note The 4R interfaces in a Cisco 7206 can be configured for 16-Mbps operation and are configured for 4-Mbps operation as a default.

For a summary of the configuration options available and instructions for configuring the 4R interfaces on the Cisco 7206, refer to the appropriate configuration publications listed in the section “If You Need More Information” on page 2.

Selecting Port Adapter Slot and Token Ring Interface Port Numbers

The following section describes how to identify port adapter slot and Token Ring interface port numbers. In the router, physical port addresses specify the actual physical location of each interface port on the router. (See .) This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:

•The first number identifies the chassis slot in which the 4R port adapter is installed.

The second number identifies interface ports on each 4R port adapter and are always numbered in sequence as interface 0 through 3.

Interface ports on the 4R port adapter maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the address changes to reflect the new slot number.

In the Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204, and slot 6 for the Cisco 7206. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present. Figure 21 shows the port adapter slots and interface ports of a Cisco 7206.

Note The I/O controller is available with or without a Fast Ethernet port. You can install both I/O controller types in all Cisco 7200 series routers; however, when you install an I/O controller with a Fast Ethernet port in a Cisco 7202, the system software automatically disables the port.

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 addresses of the interface ports on the 4R port adapter in slot 6 are 6/0 through 6/3 (chassis slot 6 and interface ports 0 through 3). If the 4R port adapter were installed in port adapter slot 4, the interface addresses would be 4/0 through 4/3.
