We have some 500 network devices and I'm concerned that setting off a discovery could cause issues to the production network. Anyone have any tips on how to treat lightly? Success stories? Things to watch out for during discovery? We're using 6.2 Enterprise Edition.

NetBrain is designed to make as few security impacts on a network as possible. For example, NetBrain utilizes an intelligent neighbor-walking algorithm, which minimizes or removes the need to scan the live network during discovery. This process emulates the workflow of a human engineer navigating from one device to another, and from one subnet to another. A NetBrain Administrator can add any subnet into the Do-Not-Scan list so that subnet will not be scanned. For a typical network node, the packet size from NetBrain is about 1kb for SNMP requests and 3-100KB for Telnet/SSH requests.

NetBrain will limit the number of discovery in the background at the same time. The default value is 48. The entire discovery process will be automatically grouped one by one. After the first group to complete the implementation of the second group.
Note: The default value can be modified, please contact support@netbraintech.com ask for help.
Discovery options: (The following is recommended options and user can change): *Discovery depths: 2 *Scan destination subnets *Scan all connected subnets *Minimum mask: 22 *Use CDP to Discover Neighbor Devices *Find Routing Protocol Neighbor via SNMP *Use CLI Routing Table to discover Next-hops *Retrieve inventory information of device/module/interface

The attached documents will help you to Perform the discovery.
