Hello,
I'm still having 2511 terminal server reverse telnet problems. This may be
a little long, but I want to provide all the details. Before I ramble on,
is there any way to verify that the 2511 line interface hardware is not
broken ? I've swapped out my octal cable and I've changed the ios version.
So here goes...
Here are the 2511 pertinent command lines:
interface Loopback0
ip address 1.1.1.10 255.255.255.255
line 1 16
no exec
transport input all
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Here are the router (2501) lines that I'm trying to successfully rev telnet
to (console port):
interface Loopback0
ip address 1.1.1.1 255.255.255.255
line con 0
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Here is the "sho line" of the 2511 before attempting the rev telnet:
Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int
0 CTY - - - - - 2
0 0/0 -
1 TTY 9600/9600 - - - - - 12 1
0/0 -
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Here is the "sho line 1" of the 2511 before attempting rev telnet:
Line 1, Location: "", Type: ""

Here is the sho line of the 2501 before rev telnet:

This is my rev telnet execution with debug out put from the console of the
2511
TermServ#tel 1.1.1.10 2001 /debug
Trying 1.1.1.10, 2001 ... Open

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
At this point, the terminal freezes and no characters echo to the terminal -
basically, it's frozen. I then do a ctrl+shift+6+x to break out and have a
look at things...this is what I see:
Output of "sho line 1" on 2511:

A "sho line," "sho line 1," and "sho session" on the 2501 is unchanged from
the original before the rev attempt.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I've also connected a modem to do a stnadard rev telnet and acces the at
command set. I set the 2511 lines to autobaud to see if it was actually
communicating with the modem and sure enough, the modem negogiated and set
the 2511 lines from 9600 to 19200. However, I get the same indications, the
session "freezes" and I can't access the at command set.
This problem is driving me crazy. I'm a little concerned that I have a
defective 2511 (bought via e-bay auction), but I don't know for isloate that
with certainty. Also, please be advised that I have scoured the archives,
CCO, and made recommended configs from others on this list, but with no
success.
Sorry for the long post, but you definetliy have all the info - need help.
thanks
