Conﬁguring the 4T Interfaces

VIP Port Adapter Functions

If you installed a new VIP or if you want to change the conﬁguration of an existing interface, you must enter Conﬁguration mode to conﬁgure the new interfaces. If you replaced a VIP that was previously conﬁgured, the system will recognize the new 4T port adapter interfaces and bring each of them up in their existing conﬁguration.

After you verify that the new 4T 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 will conﬁgure the interfaces for IP routing

Whether or not the new interfaces will use bridging

Timing source for each new interface and clock speeds for external timing

Refer to the appropriate software documentation for descriptions of the conﬁguration options available and instructions for conﬁguring a serial interface.

The following sections describe the commands for conﬁguring an external clock signal for a DCE interface and for conﬁguring a port for NRZI encoding or 32-bit CRC. Conﬁguration commands are executed from the privileged level of the EXEC command interpreter, which usually requires password access. (See the section “Using the EXEC Command Interpreter” on page 69.) Refer to the description that follows and contact your system administrator, if necessary, to obtain access.

Selecting Chassis Slot, Port Adapter, and Serial Interface Port Numbers

The following section describes how to identify chassis slot, port adapter, and serial interface port numbers.

Note Although the processor slots in the seven-slot Cisco 7000 and 13-slot Cisco 7513 are vertically oriented and those in the ﬁve-slot Cisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering. (For interface processor slot orientation in your chassis, refer to Figure 2, Figure 3, Figure 4, Figure 5, or Figure 6.)

In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 32.) This address is composed of a three-part number in the format chassis slot number/port adapter number/interface port number.

The ﬁrst number identiﬁes the chassis slot in which the VIP is installed (as shown in the example system in Figure 32). The second number identiﬁes the physical port adapter number on the VIP, and is either 0 or 1. The interface ports on each 4T port adapter are always numbered in sequence as interface 0 through 3.
