zxAnSecL3TcpC1MHalfOpenLoThresh
Module: ZTE-AN-SECURITY-L3-MIB
OID (symbolic): ZTE-AN-SECURITY-L3-MIB::zxAnSecL3TcpC1MHalfOpenLoThresh
OID (numeric): 1.3.6.1.4.1.3902.1082.70.37.2.3.1.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: TCP half-open connections lowest ratio threshold between zxAnSecL3TcpC1MHalfOpenConns and zxAnSecL3TcpC1MTotalConns in current 1 minute.
What is zxAnSecL3TcpC1MHalfOpenLoThresh?
This read-write percentage sets the lower threshold, evaluated over the current 1-minute window, for the ratio of half-open to total TCP connections used in determining zxAnSecL3TcpSynFldProtectStatus. Admins tune it alongside the non-windowed threshold to make the flood-detection logic responsive to short bursts of SYN traffic rather than only longer-term averages. For example, setting zxAnSecL3TcpC1MHalfOpenLoThresh lower than its 50% default makes the device more sensitive to brief spikes in half-open connections within any given minute.
