Description: The total number of V3 membership Block reports recieved.
What is cienaCesMcastV3ReportsRxBlock?
This counter tracks the total number of IGMPv3 membership 'Block Old Sources' reports the switch has received, which hosts send when they want to stop receiving a multicast stream from specific sources while staying joined to the group. A network admin watches this on a Ciena CES switch running IGMP snooping to spot heavy source-filtering churn, for example when a multicast video app frequently switches feed servers and each switch forces a fresh Block report. A jump from 1,200 to 1,340 in a few minutes would flag unusually active source renegotiation on a multicast group rather than a steady-state deployment.
