Confused, Traffic Shaping? Prioritizing?

[Tbarney]

Hi All,

Need some help here. I've been trying to look up the answer on my own, figure I'll learn more that way, but I can't really find what I want. I may not be asking for the right search terms. So here goes...

Cisco 2610 , these are at remote sites, connecting to my hosts at corp office.
I want to make certain types of traffic a priority. Like make sure telnet traffic gets through before e-mail... etc. Do I want to reserve a bigger part of the pipe for certain ports? or process certain types of traffic through the queue first? Any example partial configs would help...
Thanks for any help !

we have alot of terminal emulation traffic (using telnet) where i work
actually using weighted-fair queuing always sends interactive/lightweight traffic first

int e0
fair-queue

i would keep it simple and use WFQ

"Do I want to reserve a bigger part of the pipe for certain ports? or process certain types of traffic through the queue first?"

you can do either

data traffic (except routing updates) normally defaults to 'routine' precedence

in order to classify telnet traffic as critical, you need to:
define an acl with the specified traffic - telnet
access-list 123 permit tcp any any eq 23

set the precedence bit to critical/5 using a route-map
route-map whatever 10
match ip address 123
set precedence critical

all other traffic will default to normal, thus telnet will be routed first



or you could use CAR to rate-limit e-mail traffic
