Layer 2 ACL-based rate limiting
2
Editing a Layer 2 ACL Table
You can make changes to the Layer 2 ACL table definitions without unbinding and rebinding the
rate limit policy. For example, you can add a new clause to the ACL table, delete a clause from the
table, or delete the ACL table that is used by a rate limit policy.
Define rate limiting parameters
To define rate limiting parameters, enter commands such as the following:
Brocade(config)#policy-map map1
Brocade(config-policymap map1)#cir 1000000 cbs 2000000 eir 1000000 ebs 2000000
excess-dp 2
Binding Layer 2 ACL-based rate limiting policy to a port
To bind an Layer 2 ACL based rate-limiting policy on a specific port, enter commands such as the
following:
Brocade(config-policymap map1)#int eth 14/1
Brocade(config-if-e10000-14/1)# rate-limit input access-group 400 policy-map map1
Syntax: [no] rate-limit [input|output] access-group num policy-map map-name
Specifying rate limiting parameters without a policy map
To specify rate-limiting without using a policy map, enter a command such as the following:
Brocade(config-if-e10000-14/1)# rate-limit input access-group 400 49999998416
75000000000
Syntax: [no] rate-limit [input|output] access-group acl-id average-rate maximum-burst
The acl-id for Layer 2 ACLs can range from 400 to 499.
The average-rate is the maximum number of bits the policy allows during one second.
The maximum-burst parameter specifies the extra bits above the average-rate that traffic can have.
Refer to the section
“Maximum burst” on page 17 for more details. This command is only used
when configuring traffic policing directly to a port as described in “Applying traffic policing
parameters directly to a port” on page 16.
Display accounting
To display access list accounting, enter a command such as the following.
Brocade#show access-list accounting eth 14/1 in rate-limit
Collecting L2 ACL accounting for 400 on port 14/1 ... Completed successfully.
