ACL-based rate limiting policy configuration
The above commands configure a fixed rate limiting policy that allows traffic with a priority of 7 on
port 0/1/35 to transmit 1000 Kbps per second. The system rounds the configured rate to 975
Kbps. If the port transmits additional bits during a given one-second interval, the port will drop all
outbound packets on the port until the next one-second interval starts.
ACL-based rate limiting policy configuration
Brocade devices support IP ACL-based rate limiting of inbound traffic. ACL-based rate limiting
provides the facility to limit the rate for IP traffic that matches the permit conditions in extended IP
ACLs.
To configure ACL-based rate limiting, you create individual traffic policies, then reference the traffic
policies in one or more ACL entries (also called clauses or statements). The traffic policies become
effective on ports to which the ACLs are bound.
For configuration procedures for ACL-based rate limiting, refer to Chapter 42, “Traffic Policies”.
Displaying the fixed rate limiting configuration
You can display the fixed rate limiting configuration for inbound and outbound traffic.
Inbound ports
To display the fixed rate limiting configuration on inbound ports, enter the show rate-limit input
command.
