Hi,
Been working on this quite a bit and it seems to be fighting me all the way. So I can enter the following commands on the switch:
configure dot1p type 1 qp1
configure dot1p type 2 qp1
configure dot1p type 3 qp1
configure dot1p type 4 qp1
configure dot1p type 5 qp1
configure dot1p type 6 qp1
I've not changed type 7, qp7 because this is used for control traffic - guess this is primarily why it is required to have some kind of QoS method, and not completely being able to turn it off.
I re-enabled dot1p examination, and disabled diffserv examination but I'm still seeing traffic going into queues 4 and 5, even though there is no policy defining those QoS profiles, differserv examination is turned off and I've remapped dot1p?!
The other problem I have with this is that policy is remapping everything back to how it was before i.e. it keeps adding the following config back on the switches:
configure dot1p type 0 qosprofile QP1 ingress-meter ingmeter0
configure dot1p type 1 qosprofile QP2 ingress-meter ingmeter1
configure dot1p type 2 qosprofile QP3 ingress-meter ingmeter2
configure dot1p type 3 qosprofile QP4 ingress-meter ingmeter3
configure dot1p type 4 qosprofile QP5 ingress-meter ingmeter4
configure dot1p type 5 qosprofile QP6 ingress-meter ingmeter5
configure dot1p type 6 qosprofile QP6 ingress-meter ingmeter6
configure dot1p type 7 qosprofile QP8 ingress-meter ingmeter7
configure diffserv replacement priority 6 code-point 46
configure cos-index 8 qosprofile QP4 replace-tos 64
Now I believe this is due to the CoS configuration in policy manager as per the image below:
The problem with this is the "802.1p Priority" section seems to be greyed out so I can't change the values, and if I change any of the Transmit Queue / TXQ index it complains its not support.
So I can't seem to find a way to change the values below in policy, and therefore write the changes on the switch I want:
Unlike EOS device it seems summit apply the 802.1p priority tag based on egress queue not the value specified in the CoS of Policy manager, and the policy manager still seems to be geared towards EOS as I can't find a way to configure it how I want in EXOS.
Not sure if you have any thoughts?
