what netsim can not give you...

the_return_of_the_Ring

tough to get the home lab started...Here's the problem.

Problem 1: I only see "clock rate 6400" command on s0 of middle2520, why? cause I also set up the "clock rate 6400" on s1 of middle2520 and s0 of top2520?
Problem 2: I only see the serial connection between middle2520 and bottom2520 is "up & up", others are "up & down", what cuases that?

Confusion 1: Notice the configuration below. the middle2520 has a "service config" at the beginning while the other two don't have. I just bought these routers. I guess this explains why I see wired stuff interrupted me while typing config on middle2520. what do i need to do to get rid of that?

Confusion 2: what's "partition flash 2 8 8"? is it good?

I didn't have these problems while using NetSim, so u see, a real lab is 'real'.

Up down means there is a problem with the cable... I think...

The first problem I'm not sure what you're saying.

As for the two confusions, I dont see either on my routers that I got.

TheShadow

I am off to class so confusion 1 will have to wait unless others jump in. First blush check cables for proper labeling of DCE/DTE ends. Only one can set the clock.

confusion 2 is your flash is partitioned much in the same way as hard disk partitions. Someone may have been running two different files with ummm of FLH-Flash Load Helper. If it bothers you and you need a full 16 then you must check and see if it is empty. If it is then you can un-partition it with

config t
no partition flash 2 8 8
end

Chances are there is something there check with

sh flash all

Then you get to learn the erase command and how to reload flash once you join the partitions. Got to run sorry

the_return_of_the_Ring

thanx guys! I figured out problem1, 2, and confusion 2. Anything on confusion 1?
