Configuring the HSSI Interfaces

Note In the Cisco 7206 and Cisco 7206VXR router shelves, you define interfaces by type and physical shelf/port adapter/port locations. For information on Cisco 7206 and Cisco 7206VXR router shelf physical port addresses, refer to the “Identifying Chassis Slot, Port Adapter Slot, and HSSI Interface Port Numbers” section on page 7-4.

The following examples show the configuration steps required to prepare a Cisco 7000 series, Cisco 7200 series, Cisco 7500 series, and Cisco uBR7200 series routers and the Catalyst RSM/VIP2 for a null modem cable connection:

Example 1

Cisco7000/7200/uBR7246/7500Series# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Cisco7000/7200/7500Series(config)#

Enter configuration commands...

Cisco7000/7500Series(config)# interface hssi 1/0/0

Example 2

Cisco7200Series/uBR7246(config)# interface hssi 1/0

Cisco7000/7200/7500Series(config-int)# hssi internal-clock

Cisco7000/7200/7500Series(config-int)# ^z

Note For the Cisco 7206 and Cisco 7206VXR router shelves, the interface specified in the Cisco 7200 series example above would include a shelf number. For example, the command interface hssi 5/1/0 would specify the first HSSI of the port adapter in slot 1 of Cisco 7206 or Cisco 7206VXR router shelf 5.

Be sure to configure the HSSI port on both routers for an internal transmit clock. When the internal clock is enabled, the TC LED on the HSSI port adapter goes on. When the internal clock is enabled in both routers, the TC and RC LEDs on both of the connected HSSI ports go on.

When you disconnect the null modem cable, you must also disable the internal transmit clock with the command no hssi internal-clock.Use this command to turn off the transmit clock for each port on both routers.

This completes the procedure for attaching a null-modem cable to your HSSI port adapter. Proceed to the section “Configuring the HSSI Interfaces.”

Configuring the HSSI Interfaces

If you installed a new HSSI port adapter or if you want to change the configuration of an existing interface, you must enter configuration mode using the configure command. If you replaced an HSSI port adapter that was previously configured, the system will recognize each new HSSI and bring it up in its existing configuration.

After you verify that the new HSSI 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
