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

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 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 again mohammed
what cable should I use ? it looks like the async interface have more pins. is this some combination of cable that I need to use..
Thanks

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.

Thanks .. I did that .. but when I do show cdp neighbors detail , I am not seeing anything . I get
2511sw#show cdp neighbors
Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge
S - Switch, H - Host, I - IGMP, r - Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID
am I suppose to see R1 and 2950sw ? or this require more config ON ( R1 and 2950sw )
Thanks

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

Hi Karim,
Please past your entire configuration, show ip interface brief and sh line.

Mo . you know I add no exec.. to the config and now I am able to connect to r1.. I am not near the lab today .. but will let you know if any questions ..
thanks /

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:
