(Cisco) Such a simple question....

Ok, this is probably a dumb question, but I'm getting into learning how to program cisco devices and I got a hand me down catalyst 1900.  What is the telnet command to go over the serial cable to the console on this?  I know that they communicate with a 9600 baud, 8 data bits, no parity, 1 stop bit and no flow control. Anyone? Thanks!

Re: (Cisco) Such a simple question....

pacman -s minicom

You should be able to set up the connection preferences in there. You need to know the device path to your serial interface. I had usb->serial converter since my laptop doesn't have a serial port, so mine was like /dev/USB/USB1, or something. I used it a couple years ago in slackware and it works wonderfully for cisco devices, and probably any other serial connection. Just remember its not a telnet command. From wikipedia, "Minicom is a text-based modem control and terminal emulation program". Nice to see other people interested in networking gear here .

THANKS!, I just got the same information when I got to work today from my cisco buddies.  I'm fooling with my switch right now, setting up some vlans. I was just about to post up here what it was.  I wasn't aware telnet wouldnt work with a serial interface, larn something new everyday

Re: (Cisco) Such a simple question....

Ok, seeming as this is kinda the only post with any cisco information in it, thought I'd ask another question.  Hook this bad boy up and start monitoring traffic and notcie a ton of fcs errors... Initially I think its a nic, but its NOT.  so i do some googling and find that speed mismatches can cause fcs errors... low and behold set full duplex disabled and bingo fcs errors magically go away.  Cisco advises to make sure speed is set manually in the nic... but im not sure where to do this in linux, unlike windows... Help?  THANKS!!!!

Re: (Cisco) Such a simple question....

The problem is that tool doesn't seem to set the full duplex speed for the bonded virtual adapter
