I have really enjoyed learning about QoS, it's challenging. But I ran
across something so simple today that doesn't work that I'm questioning
whether I have learned anything at all....
All I wanted to do on a 6500 with Sup2's is mark all incoming traffic into
my gig1/1 from a certain source address x.x.x.x to DSCP set to EF (46), like
this:
acc 101 permit udp x.x.x.x 0.0.0.255 any
acc 101 permit tcp x.x.x.x 0.0.0.255 any
class-map match-any IncomingVoiceTraffic
match access-group 101
policy-map MarkIncomingVOIPTraffic
class IncomingVoiceTraffic
set ip dscp ef
interface GigabitEthernet1/1
ip address blah blah
service-policy input MarkIncomingVOIPTraffic
When I look with Wireshark the RTP packets for a voip session aren't getting
tagged inbound. Going back out gig1/1 is fine because the voip server is
marking the traffic properly. I'm just having trouble inbound.
Any gurus still awake?
Thanks,
CJ
