Table 2-23: Operation messages for event location VLAN (2110XXXX)
Message ID	Event Level	Message text
Message ID	Content and response
21100001	E3	IGMP snooping: IGMP querier changed on VLAN <vlan id> - lost IGMP querier address <ipv4 address>.
21100001	An advertisement (IGMPQuery) from the IGMP querier <ipv4 address >on a VLAN (<vlan id>) has disappeared. The IGMP querier information is deleted. The availability of the IPv4 multicast group member (recipient host) cannot be checked, and IPv4 multicast data forwarding is not properly executed. <vlan id>: VLAN ID <ipv4 address>: IPv4 address [Action] Check the connection with the IGMP querier <ipv4 address>. Check if the IGMP querier change message (message ID is 21100002) was output. If the connection with the IGMP querier cannot be checked, execute the configuration command ip igmp snooping querier to enable the IGMP querier function of the Switch.
21100002	E3	IGMP snooping: IGMP querier changed on VLAN <vlan id> - new IGMP querier address <ipv4 address>.
21100002	An IGMP querier was changed to <ipv4 address> because a new IGMP querier was identified on the VLAN (<vlan id>). <vlan id>: VLAN ID <ipv4 address>: IPv4 address [Action] None.
21100003	E3	IGMP snooping: IPv4 address not defined on VLAN <vlan id>,IGMP querier function stopped.
21100003	An IGMP querier on the VLAN (<vlan id>) was stopped because the IPv4 address is not set. <vlan id>: VLAN ID [Action] Set an IPv4 addresses for the appropriate VLAN. Execute the show igmp-snooping command to check that the IPv4 address set for the appropriate VLAN is displayed.
21100004	E3	IGMP snooping:The number of the IGMP snooping entry exceeded the capacity of this system.
21100004	The number of learned entries used in IGMP snooping exceeds the capacity limit of the switch. [Action] The number of entries exceeds the capacity limit. Review the system configuration and setting so that you can reduce the number of entries.
21100005	E4	The IGMP snooping entry can't be registered at hardware tables(VLAN:<vlan id> MAC address:<mac address>).
21100005	An IGMP snooping entry cannot be set in a hardware table. <vlan id>: VLAN ID <mac address>: MAC address [Action] Review the system configuration. However, depending on the hardware specification, the setting to the maximum of the capacity limit might not be available.
21100006	E3	IGMP snooping: Learning of IGMP snooping entries started because a master switch switchover occurred. (aging time = <time> seconds)
21100006	IGMP snooping entries started to be learned because the switch status changed from Backup to Master in a stacked configuration. <time> Learn Time (sec) [Action] None.
21100007	E3	IGMP snooping: Learning of IGMP snooping entries finished after a master switch switchover occurred.
21100007	Learning of IGMP snooping entries was terminated because the switch status was changed from Backup to Master in a stacked configuration. [Action] None.
21200001	E3	MLD snooping: MLD querier changed on VLAN <vlan id> - lost MLD querier address <ipv6 address>.
21200001	The MLD querier information was deleted because an advertisement (MLD Query) from the MLD querier <ipv6 address >on a VLAN (<vlan id>) disappeared. The IPv6 multicast data will not be properly relayed because the existence of the IPv6 multicast group listener (recipient host) cannot be checked. <vlan id>: VLAN ID <ipv6 address>: IPv6 address [Action] Check the connection with the MLD querier at <ipv6 address>. Check if the MLD querier change message (message ID is 21200002) was output. If the connection with the MLD querier cannot be checked, execute the configuration command ipv6 mld snooping querier to enable the MLD querier function of the Switch.
21200002	E3	MLD snooping: MLD querier changed on VLAN <vlan id> - new MLD querier address <ipv6 address>.
21200002	The MLD querier was changed to <ipv6 address> because a new MLD querier was identified on the VLAN (<vlan id>). <vlan id>: VLAN ID <ipv6 address>: IPv6 address [Action] None.
21200003	E3	MLD snooping: IPv6 address not defined on VLAN <vlan id>, MLD querier function stopped.
21200003	The MLD querier on VLAN (<vlan id>) was stopped because the IPv6 address was not set. <vlan id>: VLAN ID [Action] Set the IPv6 address for the appropriate VLAN. Execute the show mld-snooping command to check that the IPv6 address set for the appropriate VLAN is displayed.
21200004	E3	MLD snooping:The number of the MLD snooping entry exceeded the capacity of this system.
21200004	The number of learned entries used in MLD snooping exceeds the capacity limit of the switch. [Action] The number of entries exceeds the capacity limit. Review the system configuration and setting so that you can reduce the number of entries.
21200005	E4	The MLD snooping entry can't be registered at hardware tables(VLAN:<vlan id> MAC address:<mac address>).
21200005	An MLD snooping entry cannot be set in a hardware table. <vlan id>: VLAN ID <mac address>: MAC address [Action] Review the system configuration. However, depending on the hardware specification, the setting to the maximum of the capacity limit might not be available.
