Product and Software: This article applies to all Aruba controllers and ArubaOS versions.
In a big network, usually there is a lot of broadcast and multicast traffic, which consumes a large percentage of the link bandwidth. To limit that traffic, apply a bandwidth contract to the user VLAN.
The question is: will the unicast traffic be policed to the same bandwidth contract applied to the VLAN? The answer is No. A bandwidth contract applied to VLANs only polices broadcast and multicast traffic. The following is an example:
aaa bandwidth-contract BW256kbps kbits 256
interface vlan 500
ip address 220.127.116.11 255.255.255.0
