Description: Configures the Minimum allowed TCP Header size. This is active if the First Fragment Denial of Service protection feature is enabled.
What is agentSwitchDenialOfServiceTCPHdrSize?
This value sets the minimum TCP header size, in bytes, that the switch will accept once First Fragment Denial of Service protection is enabled. Packets whose TCP header falls below this threshold are treated as suspicious fragmentation-attack traffic and dropped. For example, with the default of 20 bytes (the minimum valid TCP header length), any first-fragment packet claiming a smaller header would be rejected.
