Need help with my 2950 catalyst and basic switch config

Hello all!

I am currently studying for my CCENT ICND1 and im attempting to aim to take my test at the end of january.

I am current 2, 2950 catalyst and 2, 2801 ISR cisco routers.

First im going to describe my issue.

I am somewhat familiar with the basic commands and ive configured my switches many times and erased the startup config for practice. I want you all to know due to personal reasons i was in  situation where i was unable to access my equipment for 6 months. I have been watching CBT videos and Train signal videos, I also have the ICND 1\2 series books from Wendell Odom.

I am not sure if i a completely overlooking something completely obvious and missing it or if i forgot something.

I have reset my startup config several times because of the follow:

I am having an issue with my interfaces on my SWITCHES where when i issue the "no shutdown" command. The interface will no longer be admin. shut down. The state of the interface is DOWN and so is the protocol. This is only happening when i am attempting to turn this interface into a trunk port. Ive also tried to use both of my ports on both of my switches to use them as access ports.

I also am only using 1 vlan thats been "no shutdown" issued. since im using a layer 2 device

No matter what i try or do, the link just stays down as well as the protocol.

 I tried zooming in on the interface incase anyone wanted to see but i dont think it will be much help.

I will also show you the IOS I am running.

i have used known working cables\reseated the cables and shut down and re enabled the interfaces. I also tried to put these ports into vlan 2 so they were not in the native vlan.

this is my first switch in interface 0/2

FastEthernet0/2 is down, line protocol is down (notconnect)

here is my 2nd switch on port 2

my first switch is setup the same way, the only difference is the IP in vlan 2. im using 10.1.10.1 instead.

ive also tried to do 10.1.1.1 and 10.1.1.2 for each device respectively.

end

this is the IOS i am running



Current configuration : 1328 bytes
!
version 12.1
no service pad
service timestamps debug uptime
service timestamps log uptime
no service password-encryption

i am running 12.1 on both of my switches.

now the extremely odd thing is when i connect from my laptop to the switch via ethernet cable, the ports WILL work.

Is there anyone that might have an idea or tell what i did wrong?

Hi

Try using a crossover cable for the switch to switch  connection. I don't think your 2950 supports auto-mdix

Thanks

Thank you for the idea. My switch does the support this feature. However, i do not remember the Mdix being off by default. IT needed to be enabled in order to use a straight through. The Xover cable did work as well.

actually MDIX isnt supported. i do have to use a crossover.
