If you enable LLDP on all your switches/devices... and you have an all Juniper network... you could write a JUNOScript that would do this... *and* do the OUI lookup too. Derick Winkworth CCIE #15672 (RS, SP), JNCIE-M #721 http://blinking-network.blogspot.com

It at least 'gets it right' 90ish% of the time. =) - Chris.
