I have a requirement to tag all voice traffic to the wan as DSCP field in the IP header set to ef (decimal 46).
i am currently running auto qos on the switches which are also facing the wan.
how do mark my voice traffic as such?
Do I need this on all interfaces:
auto qos voip trust
mls qos trust dscp (or cos)
or only on the phone server interfaces?
what about the interface facing the wan?
This might help.
I have found the following, does that make sense:
access-list 10 permit ip 192.168.100.0 255.255.255.0
access-list 10 permit ip 192.168.110.0 255.255.255.0
class-map match-all permium
match access-group 10
match ip dscp 46
now i can 'capture' the traffic and categories it as dscp46 but how do i apply it?
note that the vlans above are all my phones
packets with a src IP of 192.168.100.x or 192.168.110.x and a DSCP value of 46 will be matched in this class-map.
Now to make an action to these packets you must use a policy-map:
if you want to mark traffic as action then replace by set dscp ef
Then apply the policy to interface with service-policy command:
service-policy premium out
