Enabling The Mld Host Tracking Function; Setting The Dscp Value For Mld Messages; Configuring Mld Ssm Mapping - HP 6125G Configuration Manual

Enabling the MLD host tracking function

With the MLD 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 host tracking function globally
Step
1. Enter system view.
2. Enter MLD view.
3. Configure the MLD host
tracking function globally.
Enabling the MLD host tracking function on an interface
Step
1. Enter system view.
2. Enter interface view.
3. Enable the MLD host tracking
function on the interface.

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.
To set the DSCP value for MLD messages:
Step
Enter system view.
1.
2. Enter MLD view.
3. Set the DSCP value for MLD
messages.

Configuring MLD SSM mapping

Because of some possible restrictions, some receiver hosts on an SSM network might run MLDv1. To
provide SSM service support for these receiver hosts, you need to configure the MLD SSM mapping
feature on the last hop router.
