Setting the 802.1p precedence for MLD messages in a VLAN Step 1. Enter system view. 2. Enter VLAN view. 3. Set the 802.1p precedence for MLD messages. Command system-view vlan vlan-id mld-snooping dot1p-priority priority-number Remarks N/A N/A The default 802.1p precedence for MLD messages is 0. Enabling the MLD snooping host tracking function With the MLD snooping host tracking function, the switch can record the information of the member hosts that are receiving IPv6 multicast traffic, including the host IPv6 address, running duration, and timeout time. You can monitor and manage the member hosts according to the recorded information. Enabling the MLD snooping host tracking function globally Step 1. Enter system view. 2. Enter MLD-snooping view. 3. Enable the MLD snooping host tracking function globally. Command system-view mld-snooping host-tracking Enabling the MLD snooping host tracking function in a VLAN Remarks N/A N/A Disabled by default Step 1. Enter system view. 2. Enter VLAN view. 3. Enable the MLD snooping host tracking function in the VLAN. Command system-view vlan vlan-id mld-snooping host-tracking Remarks N/A N/A Disabled by default Setting the DSCP value for MLD messages IPv6 uses an eight-bit Traffic class field (called ToS in IPv4) to identify type of service for IP packets. As defined in RFC 24724, the first six bits contains the DSCP priority for prioritizing traffic in the network and the last two bits are reserved. This configuration applies to only the MLD messages that the local switch generates when the switch or its port acts as a member host, rather than those forwarded ones. To set the DSCP value for MLD messages: Step 1. Enter system view. 2. Enter MLD-snooping view. Command system-view mld-snooping Remarks N/A N/A 225
