Configuring Parameters For Mld Messages; Configuration Prerequisites - HPE FlexNetwork 5130 EI Series Configuration Manual

To speed up the response of hosts to MLD queries and to avoid simultaneous timer expirations which
cause 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 equals the MLD last
listener query interval, which is set by the last-listener-query-interval command.
•
You can configure the parameters globally for all VLANs in MLD-snooping view or for a VLAN in
VLAN view. For a VLAN, the VLAN-specific configuration takes priority over the global
configuration.
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 MLD general query
interval for the VLAN.
4. Set the maximum response
time for MLD general queries
in the VLAN.
5. 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 in a VLAN, 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 priority of MLD messages.
