Use the no version to set the time to the default, twice the query interval.
See ip igmp querier-timeout.
Use to specify how often, in the range 1–300 seconds, the interface sends group
membership queries.
Use the IGMP-Query-Interval RADIUS attribute (VSA 26-95) in RADIUS Access-Accept
messages as an alternative method of configuring this value. The RADIUS setting takes
precedence over a CLI setting.
Example
host1:boston(config-if)#ip igmp query-interval 100
Use the no version to set the polling interval to the default, 125 seconds.
See ip igmp query-interval.
Use to specify the time in tenths of a second in which the host must respond to a group
membership query. The possible period ranges are as follows:
IGMPv2: 1–255 tenths of a second
IGMPv3: 1–31744 tenths of a second
IGMPv2 and IGMPv3 include this value in IGMP query messages sent out on the interface.
You cannot set this value on interfaces running IGMPv1.
Using a lower value enables members to join and leave groups more quickly.
Use the IGMP-Max-Resp-Time RADIUS attribute (VSA 26-96) in RADIUS
Access-Accept messages as an alternative method of configuring this value. The
RADIUS setting takes precedence over a CLI setting.
Example
host1:boston(config-if)#ip igmp query-max-response-time 120
Use the no version to restore the default, 100 tenths of a second (10 seconds).
See ip igmp query-max-response-time.
Use to specify the number of times that the router sends each IGMP message from
this interface.
Use a higher value to ensure high reliability from IGMP.
Specify a number in the range 1–4.
Example
host1:boston(config-if)#ip igmp robustness 2
