System Requirements for Network Visibility Module Collector

This section identifies the management and endpoint requirements for this release. For endpoint operating system support and license requirements for each AnyConnect feature, see the AnyConnect Secure Mobility Client Features, Licenses, and OSs.

Hardware and software requirements are as follows:

  • AnyConnect Secure Mobility Client, Release 4.7 or later

  • AnyConnect NVM Profile Editor

  • If using VPN: Cisco Adaptive Security Appliance (ASA), Version 9.5.2 or later, and Cisco Adaptive Security Device Manager (ASDM), Version 7.5.1 or later

  • Any device running a supported Linux operating system to use as the NVM Collector device (Collector can run on the same server as well)

If you run Network Visibility Module Collector on a separate Linux device, you should plan for 35-40K endpoints per device, using this general scaling:

  • CPU/memory sizing can be reduced

  • Disk input/output will not be applicable since logging is only being done for the Collector and Linux

  • 50GB of disk space available to run the operating system and Collector components
