igmpCModeRxQueryVersionMismatch

Table 1. igmpCModeRxQueryVersionMismatch properties
Property name	Value
Application name	igmp
Event name	igmpCModeRxQueryVersionMismatch
Default severity	warning
Message format string	Network-instance network_instance - Mismatch between the interface subinterface compatible mode( igmpInterfaceOperVersion) and the version of the IGMP query (version igmpQuerierVersion) received on the interface.
Cause	This event is generated when the IGMP interface receives a query with a version that is higher than the interface's compatible mode.
Effect	IGMP interfaces will ignore any Queries with a version higher than the interface's compatibility mode.

igmpMaxNumberOfGroupSourcesReached

Table 2. igmpMaxNumberOfGroupSourcesReached properties
Property name	Value
Application name	igmp
Event name	igmpMaxNumberOfGroupSourcesReached
Default severity	warning
Message format string	Network-instance network_instance - The number of group/source combinations learned on interface subinterface has exceeded the maximum limit of igmpInterfaceMaxGroupSources.
Cause	This event is generated when an attempt is made to learn a source when the number of group/source combinations on the IGMP interface is equal to the maximum number of group-sources configured on the interface.
Effect	IGMP interfaces will not learn any new sources for a given group when the configured maximum number of group-sources has been reached.

igmpMaxNumberOfGroupsReached

Table 3. igmpMaxNumberOfGroupsReached properties
Property name	Value
Application name	igmp
Event name	igmpMaxNumberOfGroupsReached
Default severity	warning
Message format string	Network-instance network_instance - The number of groups learned on interface subinterface has exceeded the maximum limit of igmpInterfaceMaxGroups.
Cause	This event is generated when an attempt is made to learn a group when the number of groups on the IGMP interface is equal to the maximum number of groups configured on the interface.
Effect	IGMP interfaces will not learn any new groups when the configured maximum number of groups has been reached.

Event name	igmpMaxNumberOfSourcesReached
Default severity	warning
Message format string	Network-instance network_instance - The number of sources learned on interface subinterface has exceeded the maximum limit of igmpInterfaceMaxSources.
Cause	This event is generated when an attempt is made to learn a source when the number of sources for this group on the IGMP interface is equal to the maximum number of sources per group configured on the interface.
Effect	IGMP interfaces will not learn any new sources for a given group when the configured maximum number of sources for the group has been reached.

Event name	igmpRxQueryVersionMismatch
Default severity	warning
Message format string	Network-instance network_instance - IGMPvigmpQuerierVersion query received on interface subinterface configured as IGMPvigmpInterfaceAdminVersion.
Cause	This event is generated when the IGMP interface is configured as IGMPv3 and receives an IGMPv1 Query or IGMPv2 General Query.
Effect	IGMP interfaces configured as IGMPv3 will ignore IGMPv1 and IGMPv2 General Queries.
