QoS question

Im trying to implement a QoS config on 12.2.40. When I apply the service policy to the interface I recieve this message.

gwy02(config-if)#service-policy input inbound-internet

CEF or distributed CEF switching is required for NBAR 'match protocol' command

Im have CEF enable (this is a 3640), so Im not sure what the problem is.

Any help would be appreciated.

Re: QoS question

Hi,

Can u pls check wheter Cef is enabled on the interface , just a eg of e0/0 " sh cef interface e0/0 " might be that cef might have been removed from the interface

or try adding " ip route-cache cef " in the interface again.

Hope this helps.

regards

Re: QoS question

Hi,

u can enable cef by globl confi command ip cef,but be aware that it will be overhead on ur processor and memory as NBAR needs more processing and memory power.

rgrds,

hardik
