I'm not a Cisco certified engineer, but I have been able to manage and troubleshoot my 2600 with 2 T1s, reflexive access lists, etc.
Now I want to do some traffic shaping or limiting. I need to limit port 25 outgoing traffic, so that outgoing web requests (port 80 and 443) will not be severely impacted whenever I need to send out large quanities of email. I often need to queue up 500-1MB email messages, and when they go out, all other traffic on the router is severely crippled.
What is the simplest (lowest overhead) solution? I have "no fair-queue" configured on my outgoing T1 interface. Would "fair-queue" solve the problem without anything more complicated? Or do I need to set up an outgoing access list and policy class for either port 25 or port 80/443 traffic and use policy-map to limit the port 25 or increase the port 80/443 priority?
