Setting CoS value in 3560 switch

[tilawat.sher]

Hello,

Can someone help me how can I set the CoS value under policy map in Cisco 3560 switch IOS release 15.0. It gives me the option to set either IP Precedence or DSCP but there is no option for setting Class of Service (CoS).

Please see attached screenshot for clarity. Thanks in advance.

Hi

Cos value is added to the interface.  Polcy-map is used to set DSCP or IP-precedenace values.

have a look at this QOS doc:

Thanks Reza for responding. However, I want to assign the CoS value based on some classification specified in class map like MAC address. Therefore, I am considering this to be under policy map. How can I mark the traffic with some CoS value based on the classification. I just don't want to assign CoS to every frame that lands on an interface of the switch by adding CoS to the switch interface.

Thanks,

Tilawat

Hello,

On the inbound interface mark the traffic and set the DSCP value under policy map. Use COS to DSCP mapping on the switch.Hope this should help.
