Enabling MLD report suppression

This feature enables the switch to forward only the first MLD report for an IPv6 multicast group to its
directly connected Layer 3 device. Other reports for the same group in the same query interval are
discarded. This reduces the multicast traffic.

Setting the maximum number of IPv6 multicast groups on a
port
You can set the maximum number of IPv6 multicast groups on a port to regulate the port traffic.
Configuration restrictions and guidelines
When you set the maximum number of IPv6 multicast groups on a port, follow these guidelines:
•
This configuration takes effect only on the IPv6 multicast groups that the port joins dynamically.
•
If the number of IPv6 multicast groups on a port exceeds the limit, the system removes all the
forwarding entries related to that port. In this case, the receiver hosts attached to that port can
join IPv6 multicast groups again before the number of IPv6 multicast groups on the port
reaches the limit.
