– 582 –
receiving query packets) to have expired. (Range: 300-500 seconds;
Default: 300 seconds)
MLD Snooping Version – The protocol version used for compatibility with
other devices on the network. This is the MLD version the switch uses to send
snooping reports. (Range: 1-2; Default: 2)
Unknown Multicast Mode – The action for dealing with unknown multicast
packets. Options include:
Flood – Floods any received IPv6 multicast packets that have not been
requested by a host to all ports in the VLAN.
To Router Por t – Forwards any received IPv6 multicast packets that have
not been requested by a host to ports that are connected to a detected
multicast router. (This is the default action.)
Proxy Reporting – Enables MLD Snooping with Proxy Reporting.
(Default: Disabled)
When proxy reporting is enabled, reports received from downstream hosts are
summarized and used to build internal membership states. Proxy-reporting
devices may use the all-zeros IP source address when forwarding any
summarized reports upstream. For this reason, IGMP membership reports
received by the snooping switch must not be rejected because the source IP
address is set to 0.0.0.0.
Unsolicited Report Interval – Specifies how often the upstream interface
should transmit unsolicited MLD snooping reports when proxy reporting is
enabled. (Default: 400 seconds)
