I've got a realtime application that uses a particular port, say, 9000 for inbound and outbound UDP traffic. Since I have off-site users that can use up all my outbound bandwidth at times, when they do this, the realtime app suffers. I would love to give this port priority, so these packets go out first no matter what else is going on (I know I cannot control the order the packets arrive...). Unfortunately, I have little IOS experience. I can tweak Access lists and NAT settings, but I don't see how to do this QOS feature with my router. Is it even possible? I've been told it will support QOS, but I'm not so sure... If my current config would help, let me know and I will post it.
Thanks for any insights/direction you can provide.
What is the output from:- set ip ?
If DSCP is not vailable - then IP Precendence 5 is the same and as good as.
Once you have applied the policy - and the traffic is being marked, then you can prioritise the traffic for the app!
