Hello again,
I'm suspecting a misconfiguration between the terminal lines on the console
servers and the equipments, more specifically concerning baud rates.
Here is an output of a show line on the console :
CONS3.IX1#sh line 33
Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns
Int
33 TTY 9600/9600 - - - - - 14 0 0/0
-
Line 33, Location: "", Type: ""
Length: 24 lines, Width: 80 columns
*Baud rate (TX/RX) is 9600/9600, no parity, 1 stopbits, 8 databits*

Modem type is unknown.

Allowed input transports are pad v120 telnet rlogin udptn ssh.
Allowed output transports are pad v120 telnet rlogin ssh.
Preferred transport is telnet.
No output characters are padded
No special data dispatching characters
Here is an output of a show line cons0 on one of the core equipments :
LNS1.IX1#sh line console 0

It must some problem of this kind... Something so obvious that I'm not
seeing it.
Thanks.
