CISCO-CABLE-AVAILABILITY-MIB
AI MIB Summary
The CISCO-CABLE-AVAILABILITY-MIB manages the Hot Standby Connection to Connection Protocol (HCCP) on Cisco Cable Modem Termination Systems (CMTS) to monitor RF MAC interface states within HCCP groups and execute automatic traffic failover between Protect and Working members. It tracks specific failure conditions such as linecard crashes, interface shutdowns, and wiring faults to trigger switchover in N+1 or 1+1 redundancy configurations.
This is the MIB module for management of Hot Standby Connection to Connection Protocol (HCCP) features. HCCP is a Cisco proprietary solution for High System Availability for Cable Modem Termination Systems (CMTS).
The HCCP protocol is primarily responsible for failure detection and to initiate switchover from one CMTS to another.
The CMTS protection is at the RF mac domain level, where protecting and working CMTS cable interfaces operate on the same downstream and upstream frequency.
HCCP Terminology: HCCP group: A set of RF MAC interfaces which communicate using HCCP messaging.
HCCP member: Each RF MAC interface configured for HCCP.
Protect: A member in a HCCP group which acts as the
hot standby and protecting other members.
Working: The member in a HCCP group that is being
protected.
Thus a 'HCCP group' consists of 'HCCP members' which are RF MAC interfaces configured to function as 'Protect' or 'Working'.
Some RF mac interfaces are configured to form a 'HCCP group' and members within one 'HCCP group' communicate with each other using HCCP messaging. By HCCP messaging, some member acting as 'Protect' or hot standby can detect a failure on the other members which are designated as 'Working' in the same HCCP group. The 'Protect' can then take over traffic on the failed interface.
Protection scenarios can be N+1 or 1+1. In the N+1 protection scenario, there is only one CMTS designated for protection of N CMTS.
For example in 1+1 : When one linecard fails, the other automatically takes over its traffic. During normal operation, only one linecard forwards traffic, the other linecard stands by and listens to the messages passed from the active one. While in the standby mode, the linecard does not forward traffic. HCCP will automatically switchover to the standby in cases of software failures (crash), linecard insertion/removal, interface shutdowns and cable wiring failures etc.
Both Protect and Working are preconfigured on the CMTS and all HCCP configuration must comply with the actual cable plant deployment for correct operation of the HCCP protocol.
This MIB includes objects to support the HCCP feature on the CMTS.

ciscoCableAvailabilityMIBThis is the MIB module for management of Hot Standby
Connection to Connection Protocol (HCCP) features. HCCP is
a Cisco proprietary solution for High System Availability
for Cable Modem Termination Systems (CMTS).

detection and to initiate switchover from one CMTS to
another.
The CMTS protection is at the RF mac domain level,

Some RF mac interfaces are configured to form a

By HCCP messaging, some member acting as 'Protect' or
hot standby can detect a failure on the other members
which are designated as 'Working' in the same HCCP group.
The 'Protect' can then take over traffic on the failed

Protection scenarios can be N+1 or 1+1. In the N+1
protection scenario, there is only one CMTS designated

If the RF MAC interface is Protect, this represents
the Protect status to this member.
active(1) : The Protect is taking over and
forwarding the traffic from this Working
member which is now blocking.
standby(2) : The Protect is standby(blocking). This
means that Working member is forwarding
traffic and thus works fine.
nonFunctional(3): This member is disabled.ro Enumeration .1.3.6.1.4.1.9.9.242.1.1.5.1.4 |
ccaHCCPMemberSwitchNowThis object is used to initiate the switchover.
When it is set to true(1) and this interface is Protect,
it will cause the switchover to specified Working member.
