DisableIPParsing

Post by gramler » Fri Jul 03, 2020 5:52 pm

The virtual hub extended option help for "DisableIPParsing" says:

"If you set this option to non-zero value, then the Virtual Hub will disable the internal parsing function of IP headers in all Ethernet packets. This option can eliminate the amount of CPU and RAM usages, however the Vitual Hub will not perform building and maintenance of the IP address table internally, and some IP-related security policies will not work effectively."

What exactly does "will not work effectively." mean?
What will not work, what will be less effective and how will it impact performance.

Disabling this option on a vHub with complicated rules and +- 100 sessions drop CPU usage (over 8 nodes) from 40% above "baseline" to 2%

But which filter can/can't be used with this?
