We are getting ready to deploy 6509/Sup32's and WS-X6148A-GE-TX-AF PoE modules, as our access-layer switch. These access-layer 6509's will be layer 3 connected to distribution layer 6500s, and we will be using EIGRP as our routing protocol on all 6500s.
These will be in new buildings with all IP phones, so each port will have an IP phone and a PC connected to it.
Reading through the Cisco QOS SRND 3.3 it states (pg 2-77):
Furthermore, at the time of writing, Catalyst 6500 IOS does not yet support AutoQoS nor the
conditional-trust feature, therefore only CatOS examples of these models are given."
Now we have many 6509s as distribution and core routers running IOS, but none running CatOS at this time.
What is Cisco's "Best Practice" when using the 6500 as an access-layer switch when needing to have QOS on it?
Should I load it up with CatOS because of the availability of AutoQoS and Conditional Trust features? Or should I stick with IOS and manually configure QOS for voice and data? (With IOS and manually configuring QOS, am I still without the ability to conditionally trust DSCP values?)
If I'm able to use IOS and manually config for VoIP and data, what is an example of a standard port with an IP phone and a PC, assuming the IP phone marks the correct DSCP values and I want to trust those values?
Also we will be using Avaya IP phones so cannot use CDP.
Consider using these parameters when sending an example of QOS in an IOS environment:
data vlan = 10
voice vlan = 910
Thanks for any and all advice!
