Table 45.  Querier VLAN Status information 
Field Description
VLAN ID The VLAN ID on which IGMP snooping querier is administratively enabled and the 
VLAN exists in the VLAN database.
Operational State The operational state of the IGMP snooping querier on a VLAN. It can be in any of 
the following states:
• Querier. 
The snooping switch is the querier in the VLAN. The snooping switch 
sends out periodic queries with a time interval equal to the configured querier 
query interval. If the snooping switch finds a better querier in the VLAN, it 
moves to non-querier mode.
• Non-Querier. The snooping switch is in non-querier mode in the VLAN. If the 
querier expiry interval timer expires, the snooping switch moves into querier 
mode.
• Disabled. 
The snooping querier is not operational on the VLAN. The snooping 
querier moves to disabled mode when IGMP snooping is not operational on 
the VLAN or when the querier address is not configured or the network 
management address is also not configured.
Operational V
ersion The operational IGMP protocol version of the querier.
Last Querier Address The IP address of the last querier from which a query was snooped on the VLAN.
Last Querier Version The IGMP protocol version of the last querier from which a query was snooped on 
the VLAN.
Operational Max Response 
T
ime
The maximum response time to be used in the queries that are sent by the

View, Search, and Manage the MAC 
Address Table
You can view or configure the MAC Address Table. This table contains information about 
unicast entries for which the switch holds forwarding or filtering information. This information 
lets the transparent bridging function determine how an incoming frame must be propagated.
If you clear the MAC address entries in the MAC Address Table, only the dynamic entries are 
removed.
