discarded.

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 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.
Configuration procedure
To set the maximum number of IPv6 multicast groups on a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Set the maximum number of
IPv6 multicast groups on a
port.
