DOCS-LOADBALANCING-MIB
AI MIB Summary
The DOCS-LOADBALANCING-MIB enables CMTS management of Cable Modem (CM) load distribution by monitoring per-CM Load Balancing Groups, mobility policies, and priority values to orchestrate channel reassignments. This module provides the necessary telemetry and control points for the CMTS to dynamically migrate modems between channel sets based on defined operational constraints and load metrics.
This is the MIB Module for the load balancing. Load balancing is manageable on a per-CM basis. Each CM is assigned: a) to a set of channels (a Load Balancing Group) among which it can be moved by the CMTS b) a policy which governs if and when the CM can be moved c) a priority value which can be used by the CMTS in order to select CMs to move.

docsLoadBalanceMibThis is the MIB Module for the load balancing.
Load balancing is manageable on a per-CM basis.
Each CM is assigned:
a) to a set of channels (a Load Balancing Group) among
which it can be moved by the CMTS
b) a policy which governs if and when the CM can be moved
c) a priority value which can be used by the CMTS in order
to select CMs to move. MODULE-IDENTITY .1.3.6.1.4.1.4491.2.1.2 |

own algorithm to determine the appropriate command.rw Enumeration .1.3.6.1.4.1.4491.2.1.2.1.2.1.5 |
docsLoadBalChgOverCommitThe command to execute the DCC/UCC operation when set to
true(1).
The following are reasons for rejecting an SNMP
SET to this object:
- The MAC address in docsLoadBalChgOverMacAddr is not an
existing MAC address in docsIfCmtsMacToCmEntry.
- docsLoadBalChgOverCmd is ucc(3) and
docsLoadBalChgOverUpChannelId is '-1',
- docsLoadBalChgOverUpChannelId is '-1' and
docsLoadBalChgOverDownFrequency is '0'.
- DCC/UCC operation is currently being executed for the cable modem,
on which the new command is committed, specifically if the value of
docsLoadBalChgOverStatusValue is one of:
messageSent(1),
modemDeparting(4),
waitToSendMessage(6).
- An UCC operation is committed for a non-existing upstream
channel ID or the corresponding ifOperStatus is down(2).
- A DCC operation is committed for an invalid or non-existing
downstream frequency, or the corresponding ifOperStatus is
down(2).
In those cases, the SET is rejected with an error code
'commitFailed'.
After processing the SNMP SET the information in
docsLoadBalChgOverGroup is updated in a corresponding
entry in docsLoadBalChgOverStatusEntry.
Reading this object always returns false(2).rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.4491.2.1.2.1.2.1.6 |

Channel Change (such as DCC or UCC) operation was rejected
by the Cable modem Termination System.
timeOutT13(7):

A Restricted Load Balancing Group is associated to a specific
provisioned set of cable modems. Restricted Load Balancing
Group is used to accommodate a topology specific or provisioning
specific restriction. Example such as a group that are reserved
for business customers).
Setting this object to true(1) means it is a Restricted Load
Balancing type and setting it to false(2) means it is a
General Load Balancing group type.
This object should not be changed while its group ID is referenced

docsLoadBalGrpDefaultPolicyEach Load Balancing Group has a default Load Balancing
Policy. A policy is described by a set of conditions
(rules) that govern the load balancing process for
a cable modem. The CMTS assigns this Policy ID value to
a cable modem associated with the group ID when the cable
modem does not signal a Policy ID during registration.
The Policy ID value is intended to be a numeric reference to
a row entry in docsLoadBalPolicyEntry. However, It is not
required to have an existing or active entry in
docsLoadBalPolicyEntry when setting the value of
docsLoadBalGrpDefaultPolicy, in which case it indicates
no policy is associated with the load Balancing Group.
