Designated Shelf Controller (DSC)
In a router running Cisco IOS XR software, one RSP is assigned the role of DSC. The DSC provides
system-wide administration and control capability, including access to the administration EXEC and
administration configuration modes. For more information on DSCs, refer to Cisco ASR 9000 Series
Aggregation Services Router Getting Started Guide.
Default Configuration of the Router
When a router is brought up, the nodes assigned to the router are activated with the default software package
profile. In Cisco IOS XR software, the default software profile is defined by the last install operation.
To view the default software profile, use the show install active summary command in administration
EXEC mode. Any new nodes that are configured to the router boot with the default software profile listed in
the output of this command.
