With IGMP Snooping Querier enabled, specify the interval between general query
messages sent by the switch.
With IGMP Snooping Querier enabled, specify the host's maximum response time
to general query messages.
With IGMP Snooping Querier enabled, when the switch receives an IGMP leave
message, it obtains the address of the multicast group that the host wants to
leave from the message. Then the switch sends out group-specific queries to this
multicast group through the port receiving the leave message. This parameter
determines the interval between group-specific queries.
With IGMP Snooping Querier enabled, specify the number of group-specific
queries to be sent. If specified count of group-specific queries are sent and no
report message is received, the switch will delete the multicast address from the
multicast forwarding table.
With IGMP Snooping Querier enabled, specify the source IP address of the
general query messages sent by the switch. It should be a unicast address.
Select one or more ports to be the static router ports in the VLAN. Static router
ports do not age.
Multicast streams and IGMP packets to all groups in this VLAN will be forwarded
through the static router ports. Multicast streams and IGMP packets to the groups
that have dynamic router ports will be also forwarded through the corresponding
dynamic router ports.
Select ports to forbid them from being router ports in the VLAN.
