Cisco CMTS Configuration Commands
This means that the actual time that the Working CMTS will attempt to switch back after a switchover
is two minutes plus the revert-time. For example, if the revert-time is set to its default of 30 minutes, the
Working CMTS will attempt to switch back into operation 32 minutes after the initial switchover to the
Protect CMTS.
After the suspend time has occurred, a failure in the Protect CMTS will cause a switchover to the
Working CMTS, regardless of whether the revert-time has expired or not. You can force such a failure
in the Protect CMTS, and restore the Working CMTS to operation without waiting for the revert-time,
by using the
on the Protect CMTS.
When choosing a revert-time, take into account all possible sources of failures, including third-party
equipment. For example, an upconverter failure can trigger a switchover to the Protect CMTS. You
should configure the revert-time so that the Working CMTS does not switch back into operation until
technicians have had sufficient time to fix the equipment failure.
Tip
To disable the revert-time feature, use the no version of the
CMTS.
Examples
The following example shows cable interface 3/0 on a Working CMTS in group 2 being configured to
wait 15 minutes before automatically reverting back to working status after a system switchover:
router(config)# interface cable 3/0
router(config-if)# hccp 2 reverttime 15
The following example shows how to give the no form of this command, which resets the interface back
to its default value of 30 minutes.
router(config)# interface cable 5/1/0
router(config-if)# no hccp 2 reverttime
