3com 8807 Reference Guide

Use the igmp version command to specify the version of IGMP that a router uses.

Use the undo igmp version command to restore the default value.

The system does not automatic switching between different IGMP versions. 
Therefore, all routers on a subnet must be configured to run the same IGMP 
version.

# Run IGMP Version 1 on VLAN-interface10.
