Igmp Group-Policy - H3C S3600 Series Command Manual

Command Manual – Multicast
H3C S3600 Series Ethernet Switches-Release 1510
Caution:
No new group can be added if the number of IGMP multicast groups has exceeded
the configured limit.
If the limit on the number of IGMP packets is 1, a new group takes precedence; that
is, the system automatically replaces an existing multicast group with the new
multicast group, and the former multicast group leaves the interface automatically.
If the number of existing multicast groups on the interface is greater than the
configured limit, the system removes some existing groups automatically to satisfy
the configured limit.
Example
# Limit the maximum number of IGMP groups on Vlan-interface10 to 100.
