| Description | This attribute references the Name attribute of the
SavCfgList object of a CM. If the CM signaled group
name is not configured in the CMTS, the CMTS ignores this
attribute value for the purpose of Source Address
Verification. The CMTS must allow the modification
of the GrpName object and use the updated SAV rules for
newly discovered CPEs from CMs. When a source IP address
is claimed by two CMs (e.g., detected as duplicated),
the CMTS must use the current SAV rules defined
for both CMs in case the SAV GrpName rules may have been
updated. In the case of a persisting conflict, it is
up to vendor-implementation to decide what CM should
hold the SAV authorization.
The zero-length string indicates that no SAV Group was
signaled by the CM. The zero-length value or a non-existing
reference in the SavCfgList object means the
SavCfgListName is ignored for the purpose of SAV. |
