Chapter 2 Cisco CMTS Configuration Commands
hccp check version
hccp check version
To exit bypass version mode and return to normal Hot Standby Connection-to-Connection Protocol
(HCCP) operations for a specific HCCP group, use the
hccp check version command in privileged
EXEC mode.
hccp group check version
Syntax Description
Defaults Normal HCCP operations ( hccp group check version ), where hardware and software version checks are
made between the Working and Protect cable interface line cards.
Command Modes Privileged EXEC
Command History
Usage Guidelines By default, the Cisco CMTS verifies that the Working and Protect cable interfaces are using the same
versions of software and hardware, so as to avoid potential incompatibilities during a switchover. The
hardware check verifies that the Working and Protect cable interface line cards are compatible. The
software check verifies that the two cards are running the same major versions of software. If either of
these two conditions is not true, the CMTS by default does not perform the switchover.
You can override these version checks for a particular HCCP group by using the hccp bypass version
command. After you give this command, the Cisco CMTS does not check the hardware or software
versions of the two cable interfaces before performing a switchover. To return to normal HCCP
operations, so that version checks are made for a group, use the
hccp check version command.
Note Two cable interface line cards are compatible when the Protect card has at least the same number of
upstreams or downstreams as the Working card. The exceptions to this are that the Cisco uBR-MC16E
card can be protected only by another Cisco uBR-MC16E card. Also, the DOCSIS versions of the
Cisco uBR-MC16 card can be protected only by another Cisco uBR-MC16C card. You cannot use the
Cisco uBR-MC28C card to protect a Cisco uBR-MC16B/C/S card.
group The group number for the specified interface. The valid range is 1 to 255.
