Item	Description
enable	Indicates the state of the TCP stream reassembly function. on: The function is enabled. off: The function is disabled.
overflow-mode	Indicates the method for handling packets arriving at a full buffer in stream reassembly. discard: Packets arriving at a full buffer are discarded. forward: Packets arriving at a full buffer are forwarded straight through.
overlap-mode	Indicates the policy to handle overlapping packets: overwrite: Indicate overwrite the original overlapped part. preserve: Indicate preserve the original overlapped part.
session-cache(KB)	Indicates the buffer size in KB for each session in TCP stream reassembly.
total-cache(packets)	Global buffer size in number of packets in stream reassembly.
timestamp-check	Indicates the state of the timestamp check function. true: The function is enabled. false: The function is disabled.
tcp-option check	Indicates the state of the TCP option check function. true: The function is enabled. false: The function is disabled.
defense-check	Indicates the status of the TCP attack defense function: on: The function is enabled. off: The function is disabled.
