is enabled and operating properly, UP is displayed.
IGMP Version Version of IGMP enabled on each interface.
This Router is Group
Membership Querier
Router that was configured or elected to be the designated
group membership querier. The switch queries hosts
on each interface only when it is acting as the designated
querier on that interface.
Robustness Variable Setting for the expected packet loss on a subnet. If a
subnet is expected to have more packet loss, the
Robustness Variable should be increased. The Robustness
Variable must not be set to 0 and should not be set to 1.
Next Query Request
(sec)
Remaining amount of time (in seconds) before the next
group membership query is transmitted.
Neighbor Querier
Timeout (sec)
Amount of time (in seconds) remaining before this
interface assumes the role of designated querier. This
timer is reset to the value entered for the Neighbor
Querier Timeout Interval each time an IGMP query is
received from a neighbor with a lower IP address. If no
response is received in the allotted time, the query will
timeout and the Version 2.0 querier will begin.
Group Join Requests
Received
Number of new groups on this interface.
Group Leave Requests
Received
Number of leave requests received on this interface.
Group Reports
Received
Number of reports received on this interface in response
to a group membership query. Hosts respond to a Query
by generating Host Membership Reports reporting each
host group to which they belong on the network interface
from which the Query was received.
Query Messages
Received
Number of query messages received from other multicast
routers.
Query Messages
