Simply setting QoS COS 6 DSCP 40 on vlan 300?

I'm having trouble wrapping my head around setting qos for my NEC phones after looking at the config guide. Maybe I'm over thinking it.

I admit I'm an IOS noob- My old switches made this simple via the gui. Just hit the drop downs for COS 6 and DSCP 40 and slap it on vlan 300. 

What is the equivalent here on the 9500s?

Below you can find the template to mark any traffic coming from the interface "TenGigabitEthernet1/0/40" with a value of DSCP 40. The cos will automatically mapped by the switch over the trunk port.


ip access-list extended INGRESS //create and acl to define any traffic coming in

10 permit ip any any

 


class-map match-any adacmap //match that aacl in the class map

match access-group name INGRESS

 

policy-map ADA-policy //create a policy map and call the class map.

class adacmap

set dscp 40 // set the qos to "cs5" which is equivalent to "40"


interface TenGigabitEthernet1/0/40 //apply it under all the interface individually where you wnt your hosts to be marked as DSCP 40.

switchport access vlan 192

switchport mode access

service-policy input ADA-policy

end


You can verify the configurations by running the below command.

switch#sh policy-map interface TenGigabitEthernet1/0/40 input

You'll see packets counter incrementing under the policy that you made:

#show policy-map interface TenGigabitEthernet1/0/40 input TenGigabitEthernet1/0/40

Service-policy input: ADA-policy

Class-map: adacmap (match-any)
259020 packets
Match: access-group name INGRESS
QoS Set
dscp cs5

Class-map: class-default (match-any)
127984 packets
Match: any
