Controller Based WLANs

When a bandwidth contract is applied to a VLAN, what type of traffic will it limit: unicast, multicast, or broadcast?

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 100.1.1.1 255.255.255.0

bandwidth-contract BW256kbps
