Configuring The Maximum Number Of Multicast Groups On A Port - H3C S5600 Series Operation Manual

II. Configuring a multicast group filter in Ethernet port view
Follow these steps to configure a multicast group filter in Ethernet port view:
Enter system view
Enter Ethernet port view
Configure a multicast
group filter
Note:
A port can belong to multiple VLANs, you can configure only one ACL rule per VLAN
on a port.
If no ACL rule is configured, all the multicast groups will be filtered.
Since most devices broadcast unknown multicast packets by default, this function is
often used together with the function of dropping unknown multicast packets to
prevent multicast streams from being broadcast as unknown multicast packets to a
port blocked by this function.
The configuration performed in system view takes effect on all ports of the switch if
no VLAN is specified; if one or more VLANs are specified, the configuration takes
effect on all ports in the specified VLAN(s).
The configuration performed in Ethernet port view takes effect on the port no matter
which VLAN it belongs to if no VLAN is specified; if one or more VLANs are specified,
the configuration takes effect on the port only if the port belongs to the specified
VLAN(s).

6.2.6 Configuring the Maximum Number of Multicast Groups on a Port

By configuring the maximum number of multicast groups that can be joined on a port,
you can limit the number of multicast programs on-demand available to users, thus to
regulate traffic on the port.
Follow these steps to configure the maximum number of multicast groups on a port:
Enter system view
Enter Ethernet port view
