We have a Cisco router running this version of IOS
rsp-jk8o3sv-mz.122-17a.bin
We are implementing QoS, the QoS includes LLQ and Random-detect, DCEF is already enabled on the router, the router accepted all the QoS configuration, but we tried to implement the interface command ?service-policy output test?, it went fine with some interfaces, however other interfaces did not take the command giving us the error message ?service-policy is supported only on VIP interfaces with DCEF enabled?,again DCEF is enabled on the router.
The only difference I can spot between the interface that accepted the command and the one that did not accept was the ?PPP? on the one that did not accept the command.
Router1(config)#interface serial 2/1/7
Router1(config-if)#service-policy output test
service-policy is supported only on VIP interfaces with DCEF enabled
!
Here?s the configuration of the interface that did not take the command
interface Serial2/1/7
bandwidth 2048
no ip address
encapsulation ppp
no ip route-cache
ip ospf message-digest-key 1 md5 xxxxxxxxxxxx
no ip mroute-cache
no fair-queue
serial restart-delay 0
ppp multilink
multilink-group 100
end
I did try to implement the interface command to the multilink interface but we got the same error
Enter configuration commands, one per line. End with CNTL/Z.
Router1(config)#interface Multilink100
Router1(config-if)#service-policy output test
service-policy is supported only on VIP interfaces with DCEF enabled
Any idea why these interfaces did not accept the command?
Thanks in advance
