Re: [Netdisco] Locate a machine on the network by MAC or IPand show the switch port it lives at

[<j.v...@ut...>]

Ken,
 
The command "./netdisco -m" will execute a macsuck against every switch
that has been discovered. You can also run "./netdisco" or "./netdisco
-h" to see all command line options for the backend.
 
On Linux systems, usually "cron" is used to schedule periodic command
runs. Every user has its own crontab for commands that have to be run in
the user context. You can see the periodic commands for the Netdisco
user if you give the command "crontab -l". 
 
An example command schedule for Netdisco is included in the file
"netdisco.crontab", which you can install with the command "crontab
netdisco.crontab". If you want to edit the current schedule, use
"crontab -e". In the example crontab, macsuck is performed once every
two hours and arpnip every hour on xx:30.
 
Perhaps you already knew all of this, but since you said you're new to
the Linux world, I thought I'd just point it out.

We do have CDP turned on. I have ran that command you suggest. I can see
the entire list of my switches if I click the inventory button. But if I
search for any other IP other than workstations directly connected to
the switch I manually ran the macsuck, I don't get the switch port
information. I'm sure there is something I'm missing. 

What command will cause macsuck to run on all my switches?

If you run the ./netdisco -r x.x.x.x  it should do a discovery of all
switches.

Are you running CDP on all of your switches ?

 

I had to manually run each switch, as I am not running CDP
