Configuring 802.1P Precedence For Mld Messages - HP A5500 SI Switch Series Configuration Manual

To address this situation, enable the IPv6 multicast group replacement function on the switch or a certain
port. When the number of IPv6 multicast groups that a switch or a port has joined exceeds the limit, one
of the following occurs:
If the IPv6 multicast group replacement is not enabled, new MLD reports will be automatically
•
discarded.
If the IPv6 multicast group replacement is enabled, the IPv6 multicast group that the switch or a port
•
newly joins automatically replaces an existing IPv6 multicast group that has the lowest IPv6
address.

CAUTION:
Be sure to configure the maximum number of IPv6 multicast groups allowed on a port before enabling
IPv6 multicast group replacement. Otherwise, the IPv6 multicast group replacement functionality will not
take effect. For more information about the maximum number of IPv6 groups that a port can join, see

Configuring 802.1p precedence for MLD messages

You can change 802.1p precedence of MLD messages so that they can be assigned higher forwarding
priority when congestion occurs on their outgoing ports.
