Examples
The following example shows that all expected nodes in the Cisco CRS-1 Multishelf System are in the
run state:
RP/0/RP0/CPU0:router# show platform
Node Type PLIM State Config State

Step 7
show_bcm_links
Example:
rommon B1 > show_bcm_links
Note This step is supported on Cisco CRS-1 Multishelf
Systems only.
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 detailed information on entering
ROMMON mode.
Displays the connectivity state of the links to the onboard
Ethernet switch as well as the system control 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 is not
displayed in the output. GE Port 1 must be active, because
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.
Step 8
confreg 0x102
reset
Example:
rommon B2 > confreg 0x102
rommon B3 > reset
Exits ROMMON mode, resetting and initializing the router.
Step 9
Contact Cisco Technical Support if the problem is not
resolved.
If the problem is not resolved, contact Cisco Technical
Support. For Cisco Technical Support contact information,

“Obtaining Documentation and Submitting a
Service Request” section on page viii in the Preface.
