Hi All,


We would like to prioritize telnet traffic as well as our library system traffic. We would like to have all other traffic take up the rest of the bandwidth, and if telnet or library traffic isn't doing anything, then use up their allocation too.


Does the attached config look ok for the needed setup?


Thanks!


-Mike

It looks fine to me, but why would you mark both traffic types as "ef". "EF" is mainly used to mark VoIP packets, so in your case I think you should mark them as "AF31" instead of "EF".

I had them marked as EF from a configuration example I found online. I'll change it to AF31. What does AF31 mean?


Thanks!

AF stands for "assured forwarding", low-drop class. AF31 is mainly used for mission-critical applictions or core business traffic.
