In my organisation , i have a video conferencing unit that is natted with public IP for remote party to dial-in by IP. Now the new requirment is i need to reserve 6 Mbps of bandwidth for video/voice traffic (in/out) out of my total 32 Mbps internet bandwidth.Below is the network scenario.
We have two location ( Head quarter & Branch location) . The branch location is connected to Head Quarter over the MPLS connection of 100 Mbps.
The head quater is connected with internet connection of 32 Mbps and the branch location is accessing the internet service over MPLS WAN link. The video conferencing unit is connected on Branch location only.
WAN LINK (100Mbps) 32Mbps internet
[Video conferencing Unit]------[BR-L2Switch]----[BR-L3Switch]===================[HQ-L3Switch]----[HQ--ASA]-----[HQ-Router]------------(((( ISP )))))
Here BR denotes Branch location and HQ denotes Head quarter.
The Natting for Video conference unit is done on HQ-ASA.
The interface of HQ router that is facing to ISP is configured with subinterface and the L3Switch on both BR and HQ are 6500 series switch.
I have tried below config on HQ internet Router
access-list 120 permit tcp any any range 3230 3231
access-list 120 permit udp any any range 3230 3235
class-map match-all video-conf
match access-group 120
service-policy out video-police
As soon as I applied , the below error message was showing in router.
CBWFQ : Not supported on subinterfaces
Then i tried adding the same on BR-L3Swicth and below error message was showing.This might be because of IOS limitation.
priority command is not supported in output direction for this interface Configuration failed!
Could you please help me how to achive my requirement and where to apply the QOS with CLI commands config help.
