i will need to configure a switch of 3COM 4250T to replace a cheapo 50$ network 100Mbps auto-configured switch so that I can look at traffic incoming/outgoing to/from particular router
I have been able to telnet into the switch's built-in console. I also have plugged in the switch for usage
(NET CABLE from ISP) --> 3 COM switch ---> 4 different routers ---> internal servers on each router.
the 3COM switch itself has the capability to auto-negotiate. So far, everything is up. However, I noticed that there are several collisions (light goes yellow = only 10Mpbs).
I'm so blind of **where to start** in order to manage a switch (i was looking at concepts of layer 2 network, but it's quite hard to grasp in a matter short time - 1 week to complete this task):
1. to resolve the collision
2. to look at traffic in detail
any direction will be so helpful
