| ciscoCableAvailabilityMIB | 1.3.6.1.4.1.9.9.242 | | | 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. |

HELLO is a one-way message in HCCP sent from Protect to all
Working in the group. It indicates that Protect is ready
to receive data and expects HELLO_ACK. HELLO message
indicates the existence and state of Protect. Failing to
send this message indicates Protect is not in service. |

time of receiving the last HELLO ACK message and the time to
assume that the cable interface is out of service.
In the case of Working, it is the interval in milliseconds
between the time when the Working receives a HELLO
message and the time to assume that Protect
has failed.
In the case of Protect, it is the interval in
milliseconds between the time when the Protect sends
last HELLO message without seeing HELLO_ACK and the
time to assume that Working has failed.
It is carried by HELLO message and is used by Protect
and all Working. |

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.

it will cause the switchover to specified Working member.

Working, it will cause the switchover to the Protect in
it's protection group.
Switchover can thus be initiated by either the Protect or
the Working.
Reading this object will always return false(2). |
