show rate-limit
To display rate-limiter settings and information, use the show rate-limit command.
show rate-limit [config]
Syntax Description
Defaults This command has no default settings.
Command Types Switch command.
Command Modes Normal.
Usage Guidelines In the command output, the rate-limit status could be one of the following:
• On indicates a rate for that particular case has been set.
• Off indicates that the rate-limiter type has not been configured, and the packets for that case are not
rate limited.
• On/Sharing indicates that a particular case (not manually configured) is affected by the
configuration of another rate limiter belonging to the same sharing group.
The following restrictions apply if you want to enable rate limiting:
• Hardware-based rate limiters are supported on Catalyst 6500 series switches that are configured
with a Distributed Forwarding Card 3A (DFC3A) or the Policy Feature Card 3 (PFC3) only.
• The Catalyst 6500 series switch cannot be in truncated mode. If you attempt to enable rate limiting
and you are in truncated mode, a message appears.
If the rate limiter is enabled and some events cause the system to go from nontruncated mode to truncated
mode, rate limiting is disabled and a message appears.
Examples This example shows how to display rate-limiter settings and information:
