QOS Input policy

Ralph John Tampilic · ‎10-29-2012

Hi,

May I know what is the config for service-policy input?

I want to applied QOS output and input on the voice gateway/router. We monitored the Polycom and router both input and output. These are the configurattions we have made:

class-map match-any NetMeeting

match access-group name NetMeeting

class-map match-any CONTROL

match precedence 3

match access-group name SIGNALING

class-map match-any VIDEO

match precedence 4

match access-group name NETMEETING

class-map match-any VOICE

match access-group name VOICE

class-map match-any AUDIO

match precedence 5

policy-map QOS

class VOICE

priority percent 10

class VIDEO

bandwidth percent 50

class AUDIO

priority percent 4

class CONTROL

bandwidth percent 3

class class-default

fair-queue

random-detect

interface Serial0/0/0

description <<<<< TO MPLS-IPVPN LINK >>>>>

bandwidth 2048

no ip address

ip flow ingress

encapsulation frame-relay IETF

frame-relay lmi-type ansi

service-policy output QOS

*We have no packet loss % in transmit but receiving has.

When I am applying these configurations:

interface GigabitEthernet0/0

description <<<<<to Switch LAN going to Polycom>>>>>

ip address 192.168.4.1 255.255.255.0

ip flow ingress

duplex auto

speed auto

service-policy input QOS <--------- * I want to applied also QOS for the incoming packets to polycom. But failed.

result: low latency queuing feature not supported input policy

may I know if there is something wrong to the config of policy-map for Input? I have search for the input policy that priority/bandwidth is not supported for this policy. Is this correct? If yes, may I know how will I configure the input policy?

Highly appreciated for your immediate assistance.

Thank you very much!

Regards,

Ralph

Ralph,

I usually use input for marking/policing traffic. Do you control the other side as well? I'm assuming so....

Have you applied the same policy to both ends outbound facing the wan? Can you post "show policy-map interface s0/0/0"?

thanks for your reply

Ralph,

What's the issue? I don't see any drops on any of these classes....Have you cleared counters recently?
