We recently purchased some 4510s for some of our larger branch offices. Our Telecom department favors Avaya so we have a bunch of Avaya 9600 series IP phones. We were just assuming we'd use autoQoS but that is not an option on the Sup 7E. I'm trying to build a very basic MQC QoS config that only fixes the COS value from 6 to 5. I want to leave the default queueing alone. The Avaya phone tags as DSCP 46 and COS 6. Anyone have a working config they can share? I tried the following but it didn't seem to work, a packet capture still showed COS 6 coming from the port:
Thanks for your response. The full config for gi1/1 is:
switchport access vlan 100
switchport voice vlan 101
service-policy input SET-COS
We did the packet capture using a Fluke Omniview attached to a span port set with dot1q encapsulation. The IOS version is cat4500e-universalk9.SPA.03.02.05.SG.150-2.SG5.bin. We're just trying to respect the DSCP 46 (EF) tag presented by the phones and pass it as COS 5 also.
Apologies for the delay but i had to read up on the new QOS on 4500s. I can't see what's wrong with your config. The only thing i found was this from the config guide -
Layer 2 CoS value of the outgoing traffic
Ethernet IPv4, IPv6
DSCP value in the ToS byte
precedence value in the packet header
QoS group ID
Ethernet, IPv4, IPv6
Some of the documentation seems to suggest you can set CoS on ingress but the above is saying you can only set on outgoing traffic. The config guide cover the 6-E and 6-LE but i can't seem to find one for the 7L, unless it hasn't changed.
I'll keep searching but If all the traffic is going out a trunk link it may be worth trying to set the CoS value there instead of inbound, especially as you are not looking to do any queueing etc. on the switch.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
