Just plain scary...
by: Josh Stephens  |  Filed Under: Configuration Management
It never ceases to amaze me when I talk to companies that run large networks and don't even have the most basic of configuration management systems in place. I talked with some guys today that run a network with over 100,000 routers, switches, and firewalls and do all of their config changes by hand and don't have an easy way of backing up the device configs. I've been there - and it's a scary way to live... I think the reason for this is that so many of us have had horrible experiences with traditional configuration management solutions and we'd rather live with...

Template-based NetFlow
by: Josh Stephens  |  Filed Under: No Categories
Recently we added support for NetFlow Version 9 to the Orion NetFlow Traffic Analyzer. Since then, I've helped several customers configure their devices to correctly send NetfFlow v9 data and based upon some of the questions I'm seeing in our forums and elsewhere I figure'd it would be a good topic to write about tonight. The single most distinguising factor of Netflow v9 (which later became the basis for the IETF standard and for IPFix) is that it is template-based. In NetFlow v5, you have a fixed set of fields and the format and order of these fields are known by both...
