airFiber - How does airFiber handle QoS and frame prioritization?

Answer


airFiber is a layer-2 device with built-in quality of service (QoS) handling frame prioritization based on 802.1p priority values located in the VLAN field in the Ethernet frame header. Like with airMAX, these values should be applied prior to arriving at the airFiber in order to receive their respective prioritization.

Depending on the values configured here, airFiber will automatically prioritize the traffic accordingly:

802.1p CoS Value airFiber Priority
0 2
1 0
2 1
3 3
4 4
5 5
6 6
7 7

With this mapping, frames with 802.1p value set to 7 are the highest priority and frames with 802.1p value set to 1 are the lowest priority.
