1． Source Control Configuration
Source Control Configuration has three parts, of which the first is to enable source control. The command of
source control is as follows:
Command Explanation
Global Configuration Mode
[no] ip multicast source-control
(Required)
Enable source control globally, the “no ip
multicast source-control” command disables
source control globally. It is noticeable that, after
enabling source control globally, all multicast
packets are discarded by default. All source
control configuration can not be processed until
that it is enabled globally, while source control
can not be disabled until all configured rules are
disabled.
The next is to configure the rule of source control. It is configured in the same manner as for ACL, and uses
ACL number of 5000-5099, every rule number can be used to configure 10 rules. It is noticeable that these
rules are ordered, the front one is the one which is configured the earliest. Once the configured rules are
matched, the following rules won’t take effect, so rules of globally allow must be put at the end. The
commands are as follows:
Command Explanation
Global Configuration Mode
[no] access-list <5000-5099>
{deny|permit} ip {{<source>
<source-wildcard>}|{host-source
<source-host-ip>}|any-source}
{{<destination>
<destination-wildcard>}|{host-desti
nation
}|any-destinat
ion}
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:
