cienaCesMcastStatsQuerySrcIpZeroDiscard
Module: CIENA-CES-MCAST-FILTER-MIB
OID (symbolic): CIENA-CES-MCAST-FILTER-MIB::cienaCesMcastStatsQuerySrcIpZeroDiscard
OID (numeric): 1.3.6.1.4.1.1271.2.3.8.1.1.16
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Specifies the number of queries discarded with a zero source IP.
What is cienaCesMcastStatsQuerySrcIpZeroDiscard?
This counts IGMP queries the device discarded specifically because they had a source IP address of 0.0.0.0, which is normally treated as invalid unless the rapid-recovery mode elsewhere in this MIB has been explicitly enabled to accept such queries. An admin who enabled cienaCesMcastIgmpSnoopRapidRecoveryMode but still sees this counter incrementing would know the rapid-recovery acceptance isn't actually taking effect as expected, since queries with a zero source are still being rejected. A steadily rising count on a network not using rapid-recovery mode would simply reflect normal rejection of a query type the device intentionally treats as invalid by default.
Examples
