Setting The Maximum Number Of Igmp Snooping Forwarding Entries; Configuring Igmp Snooping Port Features; Setting Aging Timers For Dynamic Ports - HP FlexFabric 5700 Series Configuration Manual

Setting the maximum number of IGMP snooping forwarding
entries
You can modify the maximum number of IGMP snooping forwarding entries, including dynamic entries
and static entries. When the number of forwarding entries on the device reaches the upper limit, the
device does not automatically remove any existing entries. To allow new entries to be created, HP
recommends that you manually remove some entries.
To set the maximum number of IGMP snooping forwarding entries:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Set the maximum number of IGMP
snooping forwarding entries.

Configuring IGMP snooping port features

Before you configure IGMP snooping port features, 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 value for the port is
•
specified by the hello message. In this case, the router-aging-time or igmp-snooping
router-aging-time command does not take effect on the port.
You can set the aging timers for dynamic ports for the current VLAN in VLAN view or globally for
•
all VLANs in IGMP-snooping view. The configuration made in VLAN view takes priority over the
configuration made in IGMP-snooping view.
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.
