Procedure 1 Basic IGMP Configuration (Enterasys Matrix N-Series)
Step Task Command
1. In switch mode, configure IGMP for each VLAN
interface.
set igmp config vlan-list
{[query-interval query-interval]
[igmp-version igmpversion]
[max-resp-time max-resp-time]
[robustness robustness] [last-
mem-int last-mem-int]}
2. In switch mode, enable IGMP on each VLAN
interface.
set igmp enable vlan-list
3. In switch mode, enable IGMP querying on each of
the VLANs specified in step 2.
set igmp query-enable vlan-list
Procedure 2 Basic IGMP Configuration (SecureStack, D-Series, G-Series, and I-Series)
Step Task Command
1. In switch mode, enable IGMP globally. set igmpsnooping adminmode
enable
2. In switch mode, enable IGMP on each of the VLAN
ports.
set igmpsnooping interfacemode
port-string enable
Procedure 3 Basic IGMP Configuration (SecureStack C2 and C3 and G-Series)
Step Task Command
1. In router configuration mode, enable IGMP globally. ip igmp
2. In router configuration mode, enable IGMP on each
VLAN interface that will be required to determine
host membership on directly attached subnets.
ip igmp enable
