Purpose
Displays detailed information about backplane interfaces in
a specific location.
Places the DSC in ROMMON mode.
This command is used to confirm connectivity from the RP
or SC to the Catalyst switch in ROM monitor (ROMMON)
mode. See Cisco IOS XR ROM Monitor Guide for the Cisco
CRS-1 Router for information on entering ROMMON
mode.
Displays the connectivity state of the links to the onboard
Ethernet switch as well as the system control Ethernet plane
links to the standby RP and remote Catalyst switch.
Verify that all expected active ports are displayed. If no
connectivity is detected by a particular port, it will not be
displayed in the output. GE Port 1 must be active as this is
the port on the switch used for external connectivity. GE
Port 2 is the link to the secondary switch, so it should also
be active.
Exits ROMMON mode, resetting and initializing the router.
If the problem is not resolved, contact Cisco Technical
Support. For Cisco Technical Support contact information,
