Configuring Igmp Snooping Port Functions; Setting Aging Timers For Dynamic Ports - HP 6125XLG Ip Multicast Configuration Manual

Configuring parameters for IGMP queries and responses in a VLAN
Step
1. Enter system view.
2. Enter VLAN view.
3. Set the maximum response
time for IGMP general queries
in the VLAN.
4. Set the IGMP last member
query interval.

Configuring IGMP snooping port functions

Before you configure IGMP snooping port functions, complete the following tasks:
Enable IGMP snooping for the VLAN.
•
• Determine the aging timer for dynamic router ports.
Determine the aging timer for dynamic member ports.
•
Determine the addresses of the multicast group and multicast source.
•

Setting aging timers for dynamic ports

When you set aging timers for dynamic ports, follow these guidelines:
If the memberships of multicast groups frequently change, you can set a relatively small value for the
•
aging timer of the dynamic member ports. If the memberships of multicast groups rarely change,
you can set a relatively large value.
If a dynamic router port receives a PIMv2 hello message, the aging timer for the port is specified by
•
the hello message. In this case, the router-aging-time command or the igmp-snooping
router-aging-time command does not take effect on the port.
You can set the aging timers for dynamic ports either for the current VLAN in VLAN view or globally
•
for all VLANs in IGMP-snooping view. If the configurations are made in both VLAN view and
IGMP-snooping view, the configuration made in VLAN view takes priority.
Setting the aging timers for dynamic ports globally
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Set the aging timer for dynamic
router ports globally.
4. Set the global aging timer for
dynamic member ports globally.
