Description
This command configures Internet Group Management Protocol (IGMP) timers and counters.
Syntax
Usage Guidelines
IGMP is used to establish and manage IP multicast group membership. See RFC 3376, “Internet Group
Management Protocol, version 3” for more information.
Example
The following command configures IGMP:
(host) (config) #ip igmp
Parameter Description Range Default
last-member-query-
count
Number of group-specific queries that the controller sends
before assuming that there are no local group members.
1-65535 2
last-member-query-
interval
Maximum time, in seconds, that can elapse between group-
specific query messages.
1-65535
seconds
10 seconds
max-members-per-group Configure maximum members per group. 1-65535 300
query-interval Interval, in seconds, at which the controller sends host-query
messages to the multicast group address 224.0.0.1 to solicit
group membership information.
1-65535
seconds
125 seconds
query-response-
interval
Maximum time, in 1/10th seconds, that can elapse between
when the controller sends a host-query message and when it
receives a response. This must be less than the query-interval.
1-65535
seconds
100 (10
seconds)
quick-client-
convergence
Trigger IGMP reports from client during roaming. — —
robustness-variable Increase this value to allow for expected packet loss on a
subnetwork.
2-10 2
startup-query-count Number of queries that the controller sends out on startup,
separated by startup-query-interval. The default is the
robustness-variable value.
1-65535 2
startup-query-interval Interval, in seconds, at which the controller sends general
queries on startup.
1-65535
seconds

query
interval
version-1-router-
present-timeout
Timeout, in seconds, if a version 1 IGM router is detected. 1-65535
