Module: CIENA-CES-MCAST-FILTER-MIB
OID (symbolic): CIENA-CES-MCAST-FILTER-MIB::cienaCesMcastFilterGroupCompatibilityMode
OID (numeric): 1.3.6.1.4.1.1271.2.1.37.1.2.1.1.8
Node type: OBJECT-TYPE
Type: IgmpCompatibilityMode
Access: read-only
Description: The group compatibility mode for this group based on the lowest version of IGMP membership reports recieved for this multicast stream.
What is cienaCesMcastFilterGroupCompatibilityMode?
This reports the IGMP compatibility mode this specific group has settled into, determined by the lowest, oldest, IGMP version seen in any membership report received for that group, meaning a single legacy v1 or v2 host can force the whole group into a downgraded mode. An admin troubleshooting why source-specific filtering isn't working for one particular group, while others on the same service work fine, should check this field, since it isolates the problem to a legacy receiver specifically joined to that group rather than a device-wide issue. A value indicating v2 compatibility on an otherwise all-v3 network would point directly at one legacy host somewhere in that group's membership.
