Controller Based WLANs

What are the different CP bandwidth contracts?

Product and Software: This article applies to ArubaOS 3.4 or later.

Control Processor (CP) bandwidth contracts have changed starting with ArubaOS 3.4. As shown in the following example, the output of the 'datapath' command lists CP bandwidth contracts too.

0    7           2000128           0         7813         0/0 


If a contract is user-defined, CPU will be a non-zero value. For all system bandwidth contracts, CPU will be 0.

This table lists the details of these bandwidth contracts.

CPU

Contract

Description

0

1

This contract is for unicast untrusted traffic over untrusted or untrusted users.

0

2
