I have a Cisco AS2511-RJ I am using as a terminal server to 3560 switches, I also have an SRX100 and SRX210 that I would like to connect to using the Cisco Terminal Server but I am unable to achieve this, I get gibberish when using the Terminal Server config for the Cisco devices, I would be grateful for help or directions if it is at all possible to connect to the SRX devices using the AS2511.
Gibberish means the port speed is wrong -- or flow control isn't setup correctly and it's overflowing.
Nothing at all means the wiring is wrong. Don't assume Cisco and Juniper use the same pinouts. Of course, it could simply be DTE vs DCE (tx/rx swapped)
Here's how I have a line configured to access a 2948G-L3:
line .... session-timeout 30 no motd-banner exec-timeout 0 0 modem DTR-active transport input telnet stopbits 1 speed 38400
(authentication is required on that port)
