Not able to configure LLQ for Voice in 6500 series switch

Hi

I am facing a issue while configuring Qos for voice in gig port of 6500 series switch.

The error i got is " bandwidth command not supported ".

My configuration is as below:

class-map match-any voice-traffic

match protocol rtp audio

match ip dscp ef

match access-group 171

class-map match-any signalling-traffic

match ip dscp cs3

match ip dscp af31

match protocol h323

match protocol sip

match protocol mgcp

match protocol skinny

match access-group 172

policy-map voice-policy-pmap

class signalling-traffic

bandwidth remaining percent 5

class voice-traffic

priority percent 50

class class-default

fair-queue

access-list 171 permit udp any range 16384 32767 any precedence critical

access-list 171 permit udp any range 3230 3235 any precedence critical

access-list 171 permit udp any range 49152 65535 any precedence critical

access-list 171 permit ip any any dscp ef

access-list 171 permit ip any any dscp cs3

access-list 172 permit tcp any eq 1720 any

access-list 172 permit tcp any range 3230 3231 any

access-list 172 permit tcp any range 11000 12500 any

access-list 172 permit tcp any eq 2720 any

access-list 172 permit ip any any dscp cs3

!

While i am trying to apply the policy in gig port i am getting the mentioned error. I serached for the document for the ios version and cane to know that bandwidth command is not supported .

My version is " s72033-advipservicesk9-vz.122-33.SXH4.bin ".

Plz let me know any alrenate way to configure the Qos for voice.

It will e very helpful

Thanks

Re: Not able to configure LLQ for Voice in 6500 series switch

You are facing a hardware limitation, not an OS limitation, as the regular line cards rely on PFC QoS.

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/qos.html

If you want to perform extensive QoS in the 6500 platform, I highly suggest purchasing a SPA/SIP module.
