Hi Karim,


I am very glade that you are enjoying your lab :)


Just to refresh you, here you are all that you need on the comm-server:



interface loopback 0

ip address x.x.x.x y.y.y.y


line 1 16

transport input telnet

stopbits 1


and then do the reverse telnet:


telnet x.x.x.x 2nnn


where nnn = the line number, ex: if 8 then nnn = 008.


Before doing this do show line, and make sure that there is no * beside the line before doing this, and if there is a * do clear line x until the * disappear.



Take care and enjoy, and i am waiting for your next question :)

Hi,


You are always welcomed :)


First use the CAB-OCTAL-ASYNC cable to connect all your devices to the comm-server to have console access to all your devices, afterwards we can discuss your lab needs and topology.

Hi,


Use one of the Async interfaces from the comm-server to connect to the console port of the 2950.

Hi,


You should be using the CAB-OCTAL-ASYNC cable, and since the CAB-OCTAL-ASYNC cable is itself rolled, you can connect each cable directly to the console ports of devices with the RJ-45 interfaces.

Hi,


CDP don't run over console ports, accordingly it won't show CDP neighbors in this manner.

Hi Karim,


I am glade it worked out, but this is not logical as "no exec" is just used for security measures ensuring that the line never becomes unavailable due to a rogue EXEC process (To insure that unwanted signals from the attached device can't launch an EXEC session to the comm-server).


Please use this document as a reference, and please never hesitate for further questions:

And again, please do enjoy your lab :)
