The rule used to configure source control.
This rule does not take effect until it is applied
to specified port. Using the NO form of it can
delete specified rule.
The last is to configure the configured rule to specified port.
Note: If the rules being configured will occupy the table entries of hardware, configuring
too many rules will result in configuration failure caused by bottom table entries being full,
so we suggest user to use the simplest rules if possible. The configuration rules are as
follows:
Command
Explanation
Port Configuration Mode
[no] ip multicast source-control
access-group <
5000-5099
>
Used to configure the rules source control
uses to port, the NO form cancels the
configuration.

Destination Control Configuration
Like source control configuration, destination control configuration also has three
steps.
First, enable destination control globally. Since destination control need to prevent
unauthorized user from receiving multicast data, the switch won‘t broadcast the multicast
data it received after configuring global destination control. Therefore, It should be
avoided to connect two or more other Layer 3 switches in the same VLAN on a switch on
which destination control is enabled. The configuration commands are as follows:

Global Configuration Mode
[no]

and
IPv6destination control. The no
operation of this command will
globally disable destination control.
All of the other configuration can
only take effect after globally
enabled. The next is configuring
destination control rules, which are
similar.
