Configuring An Ipv6 Multicast Group Filter; Configuring Ipv6 Multicast Source Port Filtering - HP 4800G Series Configuration Manual

IPv6 ACL rule for IPv6 multicast group filtering
The maximum number of IPv6 multicast groups that can pass the ports

Configuring an IPv6 Multicast Group Filter

On a MLD Snooping–enabled switch, the configuration of an IPv6 multicast group filter allows the
service provider to define limits of multicast programs available to different users.
In an actual application, when a user requests a multicast program, the user's host initiates an MLD
report. Upon receiving this report message, the switch checks the report against the configured ACL
rule. If the port on which the report was received can join this IPv6 multicast group, the switch adds an
entry for this port in the MLD Snooping forwarding table; otherwise the switch drops this report message.
Any IPv6 multicast data that fails the ACL check will not be sent to this port. In this way, the service
provider can control the VOD programs provided for multicast users.

Configuring IPv6 Multicast Source Port Filtering

With the IPv6 multicast source port filtering feature enabled on a port, the port can be connected with
IPv6 multicast receivers only rather than with multicast sources, because the port will block all IPv6
multicast data packets while it permits multicast protocol packets to pass.
Use the command...
system-view
mld-snooping
group-policy acl6-number
[ vlan vlan-list ]
Use the command...

By default, no group filter is globally
configured, that is, hosts in VLANs
can join any valid IPv6 multicast
group.
