Cisco 3750

There are a ton of 3750s on our network.
When I need to find a machine, I do the
following:
a) Log into a switch
b) Ping the ip of the machine
c) check "show ip arp | incl ip"
d) check "show mac-address-table | incl the.mac.address"
e) if it returns Po1 or ports 25-28, I logon
to the next switch, until I get a port
listing in the range of 1-24 (which may
be off a member of the switch if I'm dealing
with a cluster.).

Is there an easier way to identify this
from a single switch? Instead of logging
on to a switch until you find
which switch the machine is connected
to?

I use 'traceroute mac add1 add2'.

Example:

xxxsw1#traceroute mac 0015.60a0.9442 0015.60a0.949e
Source 0015.60a0.9442 found on yyysw12
1 yyysw12 (n.n.n.45) : Fa0/2 => Fa0/24
2 yyysw1 (n.n.n.41) : Fa0/21 => Gi0/2
3 zzzsw2 (n.n.n.12) : Gi0/4 => Gi0/5
4 yyysw3 (n.n.n.72) : Gi0/2 => Fa0/13
Destination 0015.60a0.949e found on yyysw3
Layer 2 trace completed
xxxsw1#


You need two addresses on same vlan though.

I like to use the tool called NeDi. It is fairly easy to install and
configure and it workes pretty well.

http://nedi.sourceforge.net/about.html

Not from a single switch as such, but I've found Netdisco [netdisco.org]
to do that [and more] on Cisco and HP LANs. It does basically what you've
described by polling switches with SNMP and putting the results in an SQL
database. You're then provided with a web interface to the data to do
with what you will. It'll also let you down a switchport through the web
interface, if you're into that kind of thing.
