•
When you define a TPD, reference the TPD in an ACL entry, and then apply the ACL to a VE in the
Layer 3 router code, the rate limit policy is accumulative for all of the ports in the port region. If the
VE or VLAN contains ports that are in different port regions, the rate limit policy is applied per port
region.
For example, TPD1 has a rate limit policy of 600M and is referenced in ACL 101. ACL 101 is applied to
VE 1, which contains ports e 1/11 to e 1/14. Because ports e 1/11 and 1/12 are in a different port region
than e 1/13 and 1/14, the rate limit policy will be 600M for ports e 1/11 and 1/12, and 600M for ports e
1/13 and 1/14.
Maximum number of traffic policies supported on a device
The maximum number of supported active traffic policies is a system-wide parameter and depends on
the device you are configuring, as follows:
•
By default, up to 1024 active traffic policies are supported on Layer 2 switches. This value is fixed
on Layer 2 switches and cannot be modified.
•
For FastIron devices other than the FCX, the number of active traffic policies supported on Layer 3
switches varies depending on the configuration and the available system memory. The default
value and also the maximum number of traffic policies supported on Layer 3 switches is 50.
•
On FCX devices, up to 1024 active traffic policies are supported on Layer 3 switches. This is the
default value as well as the maximum value.
•
The maximum number of active TPDs (traffic policy definitions) supported by Brocade ICX 6650 is
896.
NOTE
On FCX devices, by default 992 of the maximum of 1024 active traffic policies are applied. The other 32
are reserved and the show traffic command returns zero references/bindings beyond the 992 traffic
policies.The show default values command displays the maximum number of traffic conditioners that
