Setting aging timers for dynamic ports
When you set aging timers for dynamic ports, follow these restrictions and 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 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.
•
MLD multicast-address-specific queries originated by the Layer 2 device trigger the adjustment
of aging timers of dynamic member ports. If a dynamic member port receives such a query, its
aging timer is set to twice the MLD last listener query interval. For more information about
setting the MLD last listener query interval on the Layer 2 device, see "Setting the MLD last
•
You can set the timers globally for all VLANs and VSIs in MLD-snooping view, for a VSI in VSI
view, or for a VLAN in VLAN view. For a VSI, the VSI-specific configuration takes priority over
the global configuration. For a VLAN, the VLAN-specific configuration takes priority over the
global configuration.
