Setting The Query Interval - Dell PowerConnect B-RX Configuration Manual

If a client sends a leave message, the client is immediately removed from the group. If a client does
not send a report during the specified group membership time (the default is 140 seconds), that
client is removed from the tracking list.
To enable the tracking and fast leave feature, enter commands such as the following.
BigIron RX(config)# interface ve 13
BigIron RX(config-vif-13)# ip igmp tracking
Syntax: ip igmp tracking
NOTE
IGMPv2 tracking will not operate correctly if the system is reloaded.
NOTE
IGMP tracking is not supported when an IGMPv3-configured port is in the EXCLUDE mode.
Creating a static IGMP group
To configure a physical port to be a permanent (static) member of an IGMP group, enter the
following commands
BigIron RX(config)# interface ethernet 1/5
BigIron RX(config-if-e1000-1/5)# ip igmp static-group 224.10.1.1
Syntax: [no] ip igmp static-group <ip-address>
Enter the IP address of the static IGMP group for <ip-address>.
To configure a virtual port to be a permanent (static) member of an IGMP group, enter the following
commands
BigIron RX(config)# interface ve 10
BigIron RX(config-vif-10)# ip igmp static-group 224.10.1.1 ethernet 1/5
Syntax: [no] ip igmp static-group <ip-address> ethernet <slot-number>/<port-number>
Enter the IP address of the static IGMP group for <ip-address>.
Enter the ID of the physical port of the VLAN that will be a member of the group for ethernet
<slot-number>/<port-number>.
NOTE
IGMPv3 does not support static IGMP group members.
NOTE
Static IGMP groups are supported only in Layer 3 mode.

Setting the query interval

The IGMP query interval period defines how often a switch will query an interface for group
membership. Possible values are 10 – 3,600 seconds and the default value is 125 seconds, but
the value you enter must be a little more than twice the group membership time.
To modify the default value for the IGMP query interval, enter the following.
BigIron RX(config)# ip igmp query-interval 120
