I'm in the unfortunate need of modifying from our previously working simplistic QoS over the WAN, configured only for voice. I have control of only the core switch, not the site router. We have a completely Cisco based voice setup, with Cisco phones (set up with auto-qos as well at the port level) and a centralized Cisco CallManager cluster over the WAN. I need to modify the following on the port going to the router:
description To WAN Router
switchport access vlan 100
switchport mode access
wrr-queue bandwidth 50 255
wrr-queue queue-limit 75 15
wrr-queue random-detect min-threshold 2 70 100
wrr-queue random-detect max-threshold 2 90 100
wrr-queue cos-map 1 2 0
wrr-queue cos-map 2 1 1 2 3 4
wrr-queue cos-map 2 2 6 7
mls qos trust cos
auto qos voip trust
I need to add the capability to add both an additional class for a prioritized data application, lets call it bitching-erp-users-because-it-is-month-end, and due to that, also a default catch-all class for the rest of the bulk.
I know that I will have to remove auto qos voip trust if I apply a different policy, but I'm unsure what's practically applied -in- auto-qos policy to reapply it with the additional classes. I'm also unsure of the correct way to apply the two data classes in such a way as to ensure the priority of the one application, and the bulk application of the rest.
Internet, please don't fail me now.
