50.3.3 IGMP Characteristic Configuration Example
All configurations about the IGMP characteristics are performed in VLAN port.
50.3.3.1 Example for changing the IGMP version
The IGMP-Router protocol of latter version is compatible with the IGMP host of low version, but cannot be
compatible with the IGMP-Router protocol of the earlier version. Therefore, if, there are switches running the
IGMP-Router protocol of the earlier version in the current network, you need to change the IGMP-Router
protocol of latter version to the IGMP-Router protocol of earliest version in the same network segment.
Suppose the administrator knows that switches running IGMP-Router V1 and IGMP-Router V2 exist in a
network that the local switch connects, the administrator needs to change the version of the IGMP-Router
protocol from version 2 to version 1 on a port of the switch that runs IGMP-Router V2.
