IOS for Class-map

[abbas.ali]

I have a 2621 router with 32M of Flash and 53M of DRAM running IOS ver. 12.1 (14).

I am not able to configure the commands below as seems like that the IOS doesn't support it.

class-map match-all VOIP_Control

match ip dscp 26

class-map match-all VOIP_Media

match ip dscp 46

!

!

policy-map VOIP

class VOIP_Control

priority 8

class VOIP_Media

priority 1536

class class-default

fair-queue

Which IOS do I need to download in order to configure these commands exactly?

For Policy-map commands as per following url, you need .T releases

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos_r/qrfcmd6.htm#1032964

so go for .T releases, 12.0(5)T and above.

The commands should take without the match-all option on the class-map. That isn't needed since theres only one match anyway. The match-all / match-any are in newer versions. Try and let us know. I'm not sure offhand when match ip dscp was first supported. You may need to upgrade to a newer 12.1T or 12.2 release if you need newer QoS features, etc.

Example:

class-map voip_control

match ..
