We have a 6509 at our core/distrubution and stacks of 3750s at the access. We are using port-chanels for the uplinks configured as trunks. All layer 3 information is on the 6509.
We are looking to deploy Alcatel IP phones which will be marking audio and signalling as ef and af31 respectively. The phones will be on their own vlan have their own dedicated ports on the 3750s (ie not sharing with the PCs)
I want to ensure voice traffic is priotised on the uplinks to the core. As I understand, I shouldn't need to do any Qos config on the ports that
connect to the handsets as they are dedicated, with the exception of 'mls qos trust dscp'. Then on the uplinks, I should just be able to use 'auto qos voip
trust' and this will transpose the DSCP markings to cos 5 and pop the voice traffic in the priority queue for the uplink to the core? Does this sound like an adequate configuration?
