Querier Election
Participation The participation mode for the IGMP snooping querier election pro-
cess:

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 peri-
odic 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.
