Chapter 2 Cisco CMTS Configuration Commands
hccp bypass version
To enter bypass version mode for a specific Hot Standby Connection-to-Connection Protocol (HCCP)
group, in which the hardware and software version checks are not performed before switching over to a
protect interface, use the hccp bypass version command in privileged EXEC mode.
Syntax Description
group
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 Release
12.2(4)XF1,
12.2(4)BC1
12.2(8)BC2
12.2(11)BC1
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
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.
OL-1581-08
hccp group bypass version
The group number for the specified interface. The valid range is 1 to 255.
Modification
This command was introduced for the Cisco uBR10012 router and
Cisco uBR-LCP-MC28C card with the Cisco RF Switch.
Support was added for the Cisco uBR10012 router using the Cisco uBR-
LCP-MC16C, Cisco uBR-LCP-MC16E, and Cisco uBR-LCP-MC16S
cards with the Cisco RF Switch.
Support was added for the Cisco uBR7246VXR router and
Cisco uBR-MC16C, Cisco uBR-MC16S, and Cisco uBR-MC28C cards
with the Cisco RF Switch.
