Configuring Static Ports - HP 5920 series Configuration Manual

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 the timer in
the hello message rather than the timer configured by using the router-aging-time command or the
igmp-snooping router-aging-time command.
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.
Setting the aging timers for the dynamic ports in a VLAN
Step
1. Enter system view.
2. Enter VLAN view.
3. Set the aging timer for the
dynamic router ports in the
VLAN.
4. Set the aging timer for the
dynamic member ports in the
VLAN.

Configuring static ports

If all hosts attached to a port are interested in the multicast data addressed to a particular multicast group
or the multicast data that a particular multicast source sends to a particular group, you can configure the
port as a static member port for the specified multicast group or the specified multicast source and group.
You can also configure a port as a static router port, through which the switch can forward all the
multicast traffic it receives.
When you configure static ports, follow these guidelines:
A static member port does not respond to queries from the IGMP querier. When you configure a
•
port as a static member port or cancel this configuration on the port, the port does not send
unsolicited IGMP reports or IGMP leave messages.
• Static member ports and static router ports never age out. To remove such a port, use the
corresponding undo command.
