To realize such requirements, you can enable the IPv6 multicast group replacement function on the switch or on a certain port. When the number of IPv6 multicast groups that the switch or the port has joined reaches the limit, one of the following occurs: • If the IPv6 multicast group replacement feature is disabled, new MLD reports are automatically discarded. • If the IPv6 multicast group replacement feature is enabled, the IPv6 multicast group that the switch or the port newly joins automatically replaces an existing IPv6 multicast group that has the lowest IPv6 address. IMPORTANT: Be sure to configure the maximum number of IPv6 multicast groups allowed on a port (see "Setting the maximum number of multicast groups that a port can join)" before enabling IPv6 multicast group replacement. Otherwise, the IPv6 multicast group replacement functionality will not take effect. Enabling IPv6 multicast group replacement globally Step 1. Enter system view. 2. Enter MLD-snooping view. 3. Enable IPv6 multicast group replacement. Command system-view mld-snooping overflow-replace [ vlan vlan-list ] Remarks N/A N/A Disabled by default Enabling IPv6 multicast group replacement for a port Step 1. Enter system view. 2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view. 3. Enable IPv6 multicast group replacement. Command system-view interface interface-type interface-number mld-snooping overflow-replace [ vlan vlan-list ] Remarks N/A Use either command. Disabled by default. Setting the 802.1p precedence for MLD messages You can change the 802.1p precedence of MLD messages so that they can be assigned higher forwarding priority when congestion occurs on their outgoing ports. Setting the 802.1p precedence for MLD messages globally Step 1. Enter system view. 2. Enter MLD-snooping view. 3. Set the 802.1p precedence for MLD messages. Command system-view mld-snooping dot1p-priority priority-number Remarks N/A N/A The default 802.1p precedence for MLD messages is 0. 224
