Configuring Parameters For Mld Messages; Configuration Prerequisites - HP MSR2003 Configuration Manual

To speed up the response of hosts to MLD queries and to avoid simultaneous timer expirations from
causing MLD report traffic bursts, you must correctly set the maximum response time.
The maximum response time for MLD general queries is set by the max-response-time command.
•
The maximum response time for MLD multicast-address-specific queries is the same as the MLD last
•
listener query interval, which is set by the last-listener-query-interval command.
You can configure parameters for MLD queries and responses either for the current VLAN in VLAN view
or globally for all VLANs in MLD-snooping view. If the configurations are made in both VLAN view and
MLD-snooping view, the configuration made in VLAN view takes priority.
Configuring parameters for MLD queries and responses globally
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Set the maximum response
time for MLD general queries.
4. Set the MLD last listener query
interval.
Configuring parameters for MLD queries and responses in a VLAN
Step
1. Enter system view.
2. Enter VLAN view.
3. Set the maximum response
time for MLD general queries in
the VLAN.
4. Set the MLD last listener query
interval in the VLAN.

Configuring parameters for MLD messages

This section describes how to configure parameters for MLD messages.

Configuration prerequisites

Before you configure parameters for MLD messages, complete the following tasks:
Enable MLD snooping for the VLAN.
•
• Determine the source IPv6 address of MLD general queries.
Determine the source IPv6 address of MLD multicast-address-specific queries.
•
Determine the source IPv6 address of MLD reports.
•
Determine the source IPv6 address of MLD done messages.
•
Determine the 802.1p precedence of MLD messages.
