Setting the maximum number of forwarding entries
for IPv6 multicast VLANs
You can set the maximum number of entries in the MLD snooping forwarding table for IPv6 multicast
VLANs. When the number of forwarding entries maintained for the IPv6 multicast VLANs reaches the
threshold, the system informs you to remove excessive entries. In this case, the system does not
automatically remove any existing entries or create new entries.
To set the maximum number of entries in the forwarding table:
Step Command Remarks
1. Enter system view. system-view N/A
2. Set the maximum number of
