Hi all,
I am trying to do this:
+------+ AUX port con port +--------+
|router|-----------------------|catalyst|
+------+ console cable +--------+
The Cisco 6500 Catalyst has a console/auxiliary port via RJ-45 (female) data terminal equipment (DTE) for local or remote connectivity.
The Cisco 1750 Series router has a RJ-45 jack with RS232 interface (plug compatible with Cisco 1000/1600/2500 series console ports); asynchronous serial DTE; transmit/receive rates up to 115.2 kbps (default 9600 bps, not a network data port); no hardware handshaking such as RTS/CTS.
Then I checked the pinout of these interfaces described here
http://www.cisco.com/warp/public/779/smbiz/service/knowledge/pinouts/ios_conaux.htm
From this document, www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_c/xtocid850646 it appears that the auxiliary port does not use Ready to Send/Clear to Send (RTS/CTS) handshaking for flow control.
So we don’t need to carry the signal on pin1 & pin8 from the AUX port.
Therefore I imagined that I could interconnect this two ports via a rolle over (console) cable.
But it seems that I am wrong and I don't see why:
From the router I tried to get connected to the swicth via its aux port and I got this where 10.0.0.1 is corresponding to its own interfaces:
------------
router# telnet 10.0.0.1 port 2000
trying 10.0.0.1, 2000 ...
% Connection refused by remote host
-------------
I also tried different port 2001...2004, 4001...4004, with the same result:connection refused by remost host.
So if you have any suggestion you are more than welcome.
Thank you.
Christophe
