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

Setting the maximum number of MLD snooping forwarding
entries
You can modify the maximum number of MLD 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 MLD snooping forwarding entries:
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Set the maximum number of
MLD snooping forwarding
entries.

Configuring MLD snooping port features

Before you configure MLD snooping port features, complete the following tasks:
Enable MLD 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 IPv6 multicast group and IPv6 multicast source.

Setting aging timers for dynamic ports

When you set aging timers for dynamic ports, follow these guidelines:
If the memberships of IPv6 multicast groups frequently change, set a relatively small value for the
•
aging timer of the dynamic member ports. If the memberships of IPv6 multicast groups rarely
change, you can set a relatively large value.
If a dynamic router port receives an IPv6 PIMv2 hello message, the aging timer value for the port
•
is specified by the hello message. In this case, the mld-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 MLD-snooping view. The configuration made in VLAN view takes priority over the
configuration made in MLD-snooping view.
Setting the aging timers for dynamic ports globally
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Set the aging timer for
dynamic router ports globally.
