Hi Roland, Thanks.
The point is i dont really know all the devices we have, so i cant be sure that they all have snmp and CDP configured. Is there a way around that? on the top of my head, i would do a port scan and based on that i would go into each device and make sure each has SNMP and CDP before i start discovering. Which open source one would you recommend ? How about CiscoWorks?
