Description: Enables or Disables the First Fragment Denial of Service protection feature.
What is agentSwitchDenialOfServiceFirstFragMode?
This read-write toggle enables or disables the switch's First Fragment denial-of-service protection feature. Admins enable this to have the switch inspect and filter the first fragment of a fragmented packet, guarding against attacks that abuse fragment reassembly to smuggle malicious headers past inspection. With agentSwitchDenialOfServiceFirstFragMode set to enable(1), a crafted fragmented packet with a too-small first fragment would be dropped by the switch.
