I need to set the DSCP value of packets arriving at a switch port to EF. This is for a 3750 running IOS version 12.2(25)SEB4.
I have the following configuration..
access-list 105 permit udp host 10.16.3.5 any
class-map match-all voip
match access-group 105
set dscp ef
description VOIP GW 10.6.1.35
switchport access vlan 250
switchport mode access
switchport voice vlan 250
ip access-group 105 in
service-policy input setdscp
UDP packets are not being marked with DSCP = EF
Any suggestions / corrections would be very helpful.
