NOTE: FortiNAC is now named FortiNAC-F. For post-9.4 articles, see FortiNAC-F. FortiNAC is a zero-trust network access solution that provides users with enhanced visibility into the Internet of Things (IoT) devices on their enterprise networks.
This article explains the issue of large infrastructure and where L2 polling takes too long, FortiNAC can be tuned for using more threads for that process.
Scope
FortiNAC all versions
Solution
The file bridgeManager.properties controls the number of threads used for Poll and Traps
By default: com.bsc.plugin.bridge.BridgeManager.pollThreads=2
Trap threads are used for trap processing, however if available are used for polling. Same goes for poll threads. Statically set pollThreads to 18 or 24 and that will allow for a 24 or more (if trap threads are free) L2 polls to be processed in parallel. Requires a restart of FNAC to take effect. If set in the property file does not persist through upgrades. To make it persist set the value in the .masterPropertyFile
With updates for trap "threads" and "pollThreads" quantities: FILE_NAME=./properties_plugin/bridgeManager.properties { com.bsc.plugin.bridge.BridgeManager.threads=12 com.bsc.plugin.bridge.BridgeManager.pollThreads=12 }
Restart FortiNAC for updates to be applied During FortiNAC startup output.master log file will document applied changes
