Easiest way to get IP of a managed switch?

[BZeto]

How do I find the IP of a managed HP ProCurve switch? They dont have it documented anywhere. Would I need to use a network scanning utility or a packet sniffer to inspect all L2 traffic?

Thanks

just use nmap and scan for open telnet ports. once you have all the IP's, telnet to each one until you find it, or use nmap's OS detection which should identify an HP ProCurve.

Or just plug a console cable in.

How do I scan the entire network and not a single host?

nmap 192.168.1.*

use a * when you need to. a basic nmap scan like that will scan for open ports on all hosts it finds. you can limit the port number with (i think) -p $PORT

i dont use it often, or for anything very specific. if you dont intend to either you can get a graphical front end with it thats too simple to misunderstand, or open the manual and search for terms.

additionally, the HP should support LLDP...check it out.

I found it using nmap. Thanks for the suggestions.
