6.4 IGMP Status
The diagram below shows an IGMP Status Overview: This can be refreshed at any
time. The IGMP v1, v2, & v3 frames will be shown in the network, the switch will only
support IGMP V2, but it will handle some IGMP V3 frames. If this switch is a Querier,
it will show Querier state and Query frames it transmitted, if it is not a Querier, it will
only show how many Querier frames it receives. Only one Querier is allowed in a
network section, usually the Querier is in router.
