Chapter 5 Cisco CMTS Debugging Commands
debug hccp plane
To display debug messages for HCCP-related messages sent between the router's control plane and data
backplane, use the debug hccp plane command in privileged EXEC mode. To disable HCCP group
debug message output, use the no form of this command.

Usage Guidelines The processor card and line cards on the Cisco uBR10012 router chassis communicate with each other
using the control plane (which is on the processor card) and the data backplane (the backplane into which
the line cards are installed). The debug hccp plane command displays debugging messages related to
the messages and packets that are transmitted between the control plane and data backplane.
You must use the
Note
hccp plane command will generate any debug output.
Examples
The following example shows typical output that is produced by the debug hccp plane message
command:

Display debugging messages for the inter-plane messages that occur.
Display a partial dump of packets that are sent between the control plane and
data backplane.
Display debugging messages related to the "heartbeat" packets that are sent
between the control plane and data backplane to synchronize events.
Modification
This command was introduced for the Cisco uBR10012 router.
Support was added for the N+1 (1:n) RF Switch with the Cisco uBR10012
router.
Support was added for the N+1 (1:n) RF Switch with the
Cisco uBR7246VXR router. The syncpulse option also was added.
