Configures the maximum number of multicast packets allowed per second and enables Syslog logging of multicast packets.

Syntax

multicast limit num

multicast limit num kbps log

multicast limit num kbps threshold num action port-shutdown num

no multicast limit num

no multicast limit num kbps log

no multicast limit num kbps threshold num action port-shutdown num

Command Default

Multicast rate limiting is disabled.

Parameters

num: Specifies the maximum number of multicast packets per second. Valid values range from 1 through 8388607.
kbps: Enables byte-based limiting. The value can be 1 to Max Port Speed.
log: Enables Syslog logging when the broadcast limit exceeds num kpbs .
threshold num: Specifies the packet drop count threshold value. Valid values range from 1 through 1048576.
action: Specifies further action must be taken.
port-shutdown: Specifies that port shutdown is the action taken.

Modes

Interface configuration mode

Usage Guidelines

Use 0 or the no form of the command to disable limiting.

Examples

The following example enables a multicast limit of 131072 kbps.

device(config)# interface ethernet 9/1/1
device(config-if-e1000-9/1/1)# multicast limit 131072 kbps

The following example enables multicast logging when the configured limit exceeds 100 Kbps.

device(config)# interface ethernet 1/2/1
device(config-if-e1000-1/2/1)# multicast limit 100 kbps log

The following example sets the packet drop count threshold value to 2000 and specifies that the port shutodwn action is taken.

device(config)# interface ethernet 1/2/1
device(config-if-e10000-1/2/1)# multicast limit 100 kbps threshold 2000 action port-shutdown 7
