Hi everybody.
I am new to Extreme, I have few questions:

p1-sw-49

On P1, i am classifying  my ingress traffic based on DCSP and put them in specific queues on egress on port 49, switch will impose vlan tag 45 and sends it out of port 49 to switching cloud


SW # show qosprofile port 49

QoS profile: None configured
Queue: Q0 using QP1  MinBw=1%  MaxBw=100%  Pri=0.
Q1 using QP2  MinBw=1%  MaxBw=100%  Pri=1.
Q2 using QP3  MinBw=1%  MaxBw=100%  Pri=2.
Q3 using QP4  MinBw=1%  MaxBw=100%  Pri=3Q4 using QP5  MinBw=1%  MaxBw=100%  Pri=4.
Q5 using QP6  MinBw=1%  MaxBw=100%  Pri=5.
Q6 using QP7  MinBw=1%  MaxBw=100%  Pri=6.
Q7 using QP8  MinBw=1%  MaxBw=100%  Pri=7


1) Are  PRI  above refers to dotp values?
2) How can I instruct my switch to impose dotp values on egress traffic on port 49 ?

( For example, in juniper, we use rewrite rule to achieve that)

3) How can i find DSCP-->QOS profile mapping?

Much appreciated!!

Hi Zeeshan,

The following link may be a good start: 
http://gtacknowledge.extremenetworks.com/articles/How_To/Configuring-QOS-profiles-and-verify-QOS-is-working/?q=Configuring+QOS+profiles+and+verify+QOS+is+working&l=en_US&fs=Search&pn=1 

1. the dot1p values for each qos profile can be identified using the command show dot1p examination. 

2. we can enable the dot1p replacement so that the switch would modify the dot1p value when egressing the switch port based on the configured qos. 

3. show diffserv examination would show the dscp - qos mapping.
