Q:

What is QOS trust mode and how to configure it in Mobility access switch?



A:

Previously on ArubaOS 7.0, only one mode of QoS trust (L2 + L3 trust) was supported Starting ArubaOS 7.1, more granular QoS trust modes are supported:

  •   Auto - L2 + L3 trust
  •  Dot1p - Trust only 802.1p bits
  •  Dscp - Trust only DSCP bits of the IP header
  •  None - Do not trust any incoming 802.1p/DSCP. Will be queued to Queue 0


QoS Trust Mode - Configuration

Interface can be configured to trust mode by following CLI

(ArubaS3500) (config) #interface gigabitethernet 0/0/21
(ArubaS3500) (gigabitethernet "0/0/21") #qos trust <auto | dot1p | dscp | none>

 

QoS Trust configuration can be verified using following CLI command:


(ArubaS3500) #show interface-config gigabitethernet 0/0/21
gigabitethernet "0/0/21"
------------------------
Parameter                                   Value

...
Interface QoS Profile                       N/A
...
Interface QoS Trust Mode                    DSCP
...


note: If qos trust mode is auto, and incoming packet is marked with both 802.1p and DSCP bits, the packet will be classified based on DSCP
