QoS on a non trunk Interface

Tshi M

Hi,

I am new to QoS and would like to setup auto QoS between my site and another site. Below is what I intend to implement on my switch (Cisco 6506-e) SUP720. Is this good enough?

switch(config)#mls qos

switch(config)#mls qos map cos-dscp 0 8 16 24 32 46 48 54

!

switch(config-if)#ip address x.x.x.x/30

switch(config-if)#mls qos trust cos

!

Hi,

One suggestion for change:

Instead of mls qos trust cos, do mls qos trust dscp

As CoS is only sent in 802.1q header (i.e. a trunked interface), it won't work. Trusting DSCP will work perfectly for L3 interfaces.

Other than that, what you have there is fine for a basic config.
