Changing the IGMP Version

By default, the switch uses IGMP Version 2, which provides features such as the IGMP query timeout and
the maximum query response time.
All systems on the subnet must support the same version. The switch does not automatically detect Version
1 systems and switch to Version 1. You can mix Version 1 and Version 2 hosts on the subnet because Version
2 routers or switches always work correctly with IGMPv1 hosts.
Configure the switch for Version 1 if your hosts do not support Version 2.
This procedure is optional.
