Netflow is CPU hungry, not supported on all products and sometimes it requires license. Based on my experience networking people do not want to run netflow because it will kill the CPU of their catalysts... Netflow on some Cisco devices is ususaly only sampling = you will not see all the traffic

What is your approach to collect and maintain network information?! I actually think about how to get all the data from Layer 1 (i.e. C2 Switch, Cisco Firewall, WAN Accelerator etc) to Layer 2 VLANs to IP Subnets... Putting it in Word or Excel doesn't seems to be very helpful... buying an expensive IPAM software is also not an option... I gladly appreciate any input ;) Bye Tom -- Thomas Hofmann, System-/Networkadministrator, IT EB - Discover the Experience Visitors: Am Wolfsmantel 46, 91058 Erlangen, Germany Phone: +49 (9131) 7701 6969, mailto:[email protected] Fax: +49 (9131) 7701 6333, http://www.elektrobit.com<http://www.elektrobit.com/> PGP-Key: http://keyserver.elektrobit.com<http://keyserver.elektrobit.com/> Elektrobit Automotive GmbH, Am Wolfsmantel 46, 91058 Erlangen, Germany Managing Director Otto Fößel Register Court Fürth HRB 4886 ---------------------------------------------------------------- Please note: This e-mail may contain confidential information intended solely for the addressee.
