Port Traffic Rate Limiting
17-18 Configuring Quality of Service
When a CoS is configured with an inbound rate limiter (IRL), and that IRL CoS is configured as
part of a policy profile using the set policy profile command, CoS-based inbound rate limiting
will take precedence over port rate limits set with set port ratelimit.
Examples
This example displays the current ratelimit configuration on port fe.1.1.
System(su)->show port ratelimit fe.1.1
Global Ratelimiting status is disabled.
Port Threshold Priority
Number Index (KBytes) Action Direction List Status
-------- -------- -------- ------------ ---------- ----------- ---------
fe.1.1 1 64 discard inbound 0-3 disabled
fe.1.1 2 64 discard inbound 4-7 disabled
This example globally enables rate limiting and then configures rate limiting for inbound traffic
on port fe.1.1, index 1, priority 0-3, to a threshold of 125 kilobytes per second.
System(su)->set port ratelimit enable
System(su)->set port ratelimit fe.1.1 0-3 125 enable inbound 1
System(su)->show port ratelimit fe.1.1
Global Ratelimiting status is enabled.
Port Threshold Priority
Number Index (KBytes) Action Direction List Status
-------- -------- -------- ------------ ---------- ----------- ---------
fe.1.1 1 125 discard inbound 0-3 enabled
fe.1.1 2 64 discard inbound 4-7 disabled
This example returns rate limit parameters for port fe.1.1 to their default values.
System(su)->clear port ratelimit fe.1.1
System(su)->show port ratelimit fe.1.1
Global Ratelimiting status is enabled.
Port Threshold Priority
Number Index (KBytes) Action Direction List Status
-------- -------- -------- ------------ ---------- ----------- ---------
