Hi Guys,
Doing some QOS on switches and I just can't get it to work, I think I've
crossed the T's and dotted the i's but it ain't working.
Setup
3560
3550
R1 fa0/0------fa0/1 SW1 fa0/13 -----TRUNK------ fa0/13 SW2
fa0/2-----------fa0/0 R2
R1
class default matching everything going out to SW and marking it as DSCP EF
SW1
mls qos
int fa0/1
mls qos trust dscp
SW2
class-map match all MATCH_EF
match ip dscp ef
policy-map MARK_EF
class MATCH_EF
trust dscp
set dscp cs4
interface fa0/13
service-policy input MARK_EF
I've configure an acl on R2 to match ip any any for all dscp values. I'm
still seeing it as EF.
When I do a show policy-map int fa0/13 I see the correct policy-map but I'm
not seeing any packets on either the MATCH_EF class or the default class.
Any ideas what I'm missing? I've configure the class-map first, then the
policy-map and then applied it to the interface so I don't think I've caused
problem with order of operation (if there was one), I've also reloaded the
switch, but still no joy.
I'd appreciate any input if you guys can.
Thanks,
