Chapter 2 Cisco Cable Modem Termination System Commands
To enter bypass version mode for a specific 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.
hccp group bypass version
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
group The group number for the specified interface. The valid range is 1 to 255.
Release Modification
12.2(4)XF1,
12.2(4)BC1
This command was introduced for the Cisco uBR10012 router and
Cisco uBR-LCP-MC28C card with the Cisco uBR-RFSW RF Switch.
12.2(8)BC2 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 uBR-RFSW RF Switch.
12.2(11)BC1 Support was added for the Cisco uBR7246VXR router and
Cisco uBR-MC16C, Cisco uBR-MC16S, and Cisco uBR-MC28C cards
with the Cisco uBR-RFSW RF Switch.
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.
