Table 207: IGMP Snooping Querier VLAN Configuration Fields
Field
Description
VLAN ID
The VLAN on which the IGMP snooping querier is enabled. When enabling the
IGMP snooping querier on a VLAN, use this menu to select the desired VLAN.
Only VLANs that have been configured on the system and are not already
enabled for the IGMP snooping querier appear in the menu. When modifying
IGMP snooping querier settings, this field identifies the VLAN that is being
configured.
Querier Election Participation
The participation mode for the IGMP snooping querier election process:
•
Enabled – The IGMP snooping querier on this VLAN participates in the
querier election process when it discovers the presence of another querier in
the VLAN. If the snooping querier finds that the other querier source IP
address is lower than its own address, it stops sending periodic queries. If the
snooping querier wins the election (because it has the lowest IP address),
then it continues sending periodic queries.
•
Disabled – When the IGMP snooping querier on this VLAN sees other
queriers of the same version in the VLAN, the snooping querier moves to the
non-querier state and stops sending periodic queries.
Querier VLAN IP Address
The IGMP snooping querier address the VLAN uses as the source IP address in
periodic IGMP queries sent on the VLAN. If this value is not configured, the VLAN
uses the global IGMP snooping querier IP address.

Table 208: IGMP Snooping Querier VLAN Configuration Fields
Field
Description
VLAN ID
The VLAN associated with the rest of the data in the row. The table includes only
VLANs that have the snooping querier enabled.
State
The operational state of the IGMP snooping querier on the VLAN, which is one of
the following:
•
Querier – The snooping switch is the querier in the VLAN. The snooping
switch will send out periodic queries with a time interval equal to the
configured querier query interval. If the snooping switch sees a better querier
(numerically lower) 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 the disabled mode when IGMP snooping is not
operational on the VLAN, when the querier address is not configured, or the
network management address is not configured.
