The amount of bandwidth that multicast traffic uses on a link
can be controlled using the interface command.
ip multicast rate-limit in | out
[video] | [whiteboard] [group-list access-list]
[source-listaccess-list] [kbps]
in
Only packets at the rate of kbps or slower are accepted on
the interface.
out
Only a maximum of kbps is transmitted on the
interface.
video
Optional. Rate-limiting is performed based on the UDP port
number used by video traffic, which is identified by consulting the
SDR cache.
whiteboard
Optional. Rate limiting is performed based on the UDP port
number used by whiteboard traffic, which is identified by consulting
the SDR cache.
group-list access-list
Optional. An access list that is used to determine which
multicast groups will be constrained by the rate limit.
source-list access-list
Optional. An access list that is used to determine which
senders will be constrained by the rate limit.
Kbps
Rate limit in kilobits per second. Packets sent at a rate
greater than kbps are
discarded. If no value is given, then the default rate is 0 kilobits
per seconds. In this case, no multicast traffic is
permitted.
This command requires that ip sdr listen be enabled so port numbers can be obtained from
the SDR cache. If SDR is not enabled, then no limiting
occurs.
