Configuring Per-Port MLD Traffic Filters

Syntax: ipv6 mld [auto <port-list> blocked <port-list> forward <port-list>]

Note: This command must be issued in a VLAN context.

This command sets per-port traffic filters, which specify how each port should handle MLD traffic. Allowed settings are: auto—follows MLD snooping rules: packets are forwarded for joined groups

blocked—all multicast packets are dropped, except that packets for well known addresses are forwarded

forward—all multicast packets are forwarded

The default value of the filter is auto.

<port-list>—specifies the affected port or range of ports

For example:

ProCurve(vlan-8)# ipv6 mld forward a16-a18

ProCurve(vlan-8)# ipv6 mld blocked a19-a21

ProCurve(vlan-8)# show ipv6 mld vlan 8 config
