Quality of Service on Avaya ERS 45xx - Validation

[ginou]

Hi everyone,
i need to validate a QoS configuration i've done.

The goal in my case is to put a high priority to a VLAN which use for Voice over IP.
Our voice VLAN had the ID 403.
so, i want high priority for the VLAN 403 compared other VLAN
ports 1 to 47 are untag pvid only
ports 48 and 49 are trunks

The ascii configuration on the switch is :

---------------
! *** QOS ***
!
qos if-group name "XIVO_QOS" class trusted
qos action 10 name "XIVO_PRIORITE_6" drop-action disable update-1p 6
qos l2-element 2 name "XIVO_QOS" vlan-min 403 vlan-max 403 vlan-tag untagged ethertype 0x800 priority 6
qos classifier 1 set-id 1 name "XIVO_QOS" element-type l2 element-id 2
qos classifier-block 1 block-number 1 name "XIVO_QOS" set-id 1 in-profile-action 10 eval-order 1
qos if-assign port 1-47 name XIVO_QOS
qos policy 2 name "XIVO_POLICY" if-group "XIVO_QOS" clfr-type block clfr-id 1 precedence 6 track-statistics individual
qos if-assign port 49-50 name $qosDisabledIfcs
---------------

I've test this with a stress test and it work fine, without the QoS the voice is jerky and with the QoS the voice is clear.

It woud be a really good thing if someone can tell me if this configuration is optimized.

Sorry for my approximative english.
Thanks .
