Creating a Network

Applies to Product: USM Appliance™ LevelBlue OSSIM®

In USM Appliance, you can create a network either manually or by importing a CSV file.

Creating a Network by Importing a CSV File

LevelBlueUSM Appliance allows users to import networks from a CSV file. The allowed formats consist of the following:

"Netname"*;"CIDRs(CIDR1,CIDR2,...)"*;"Description";"Asset Value"*;"Net ID"


  • The delimiter is a semicolon.
  • The Netname, CIDRs, and Asset Value fields are mandatory.
  • The Netname field allows these characters: A-Z, a-z, 0-9, ., :, _, and -.

Each CSV file must contain a header row:

"Netname";"CIDRs";"Description";"Asset Value";"Net ID"

For example, with the file below, you add a network with a CIDR of and

"Netname";"CIDRs;"Description";"Asset Value";"Net ID"

"Net_1";",";"This is my network";"2";"479D45C0BBF22B4458BD2F8EE09ECAC2"
