Connecting to the Router Through the Console Port

Note Any LCC can host the DSC. The FCC cannot host the DSC function.

Selecting and Identifying the DSC on Cisco XR 12000 and 12000 Series Routers

A Cisco XR 12000 or 12000 Series router supports multiple PRPs. When the router is started for the first time, the PRP in the lowest-numbered slot becomes the active PRP and is identified by the alphanumeric display: ACTV RP. The active PRP serves as the DSC. If another PRP is configured as a standby PRP for the DSC, that PRP can assume the DSC role if the DSC fails.

To have a PRP in a higher-numbered slot become the DSC, you must bring up the router with only that PRP installed. After the chosen PRP becomes the DSC, it remains the DSC after subsequent restarts and you can add the other PRPs.

Note Additional PRPs can be installed to host secure domain routers (SDRs), which are introduced in Chapter 4, “Configuring General Router Features.” To configure general router features, you must connect to the DSC. To configure SDR features, you must connect to the PRP for the appropriate SDR.

Connecting to the Router Through the Console Port

The first time you connect to a new router with Cisco IOS XR software, you must connect through the Console port on the DSC. Although typical router configuration and management take place using an Ethernet port on the DSC, this port must be configured for your local area network before it can be used.

Figure 1-4shows the RP connections on the Cisco CRS-1 16-Slot Line Card Chassis, and Figure 1-5shows the RP connections on the Cisco CRS-1 4-Slot Line Card Chassis and Cisco CRS-1 8-Slot Line Card Chassis. Figure 1-6shows the PRP-2 connections on the Cisco XR 12000 Series Router.

Note Cisco IOS XR software does not support the PRP-1.
