class default qos

[tedauction]

Hello, if I apply the following policy map to an interface, does this simply make all traffic on that interface get marked with EF ?

policy-map CODEC
 class class-default
  set dscp ef

[Mark Malone]

I wouldn't use the default qos map that's only for when all other policy statements have been set and whatevers left the default class will use for bandwidth  , set your own policy and apply it to the interface to match traffic coming in ., you can tighten it to the voice subnet in the acl

class-map MAPVOICE

match access-group 100

policy-map TEST

class MAPVOICE

set dscp EF

access-list 100 permit ip any any

Hello
Yes it does if you apply it to an interface.

note:
ip dscp ef= ivp4 packet
dscp ef = ipv4 and ipv6 packets

Yes, although if used as an ingress policy, another port's egress policy could remark the traffic.
