zxAnSecL3TcpC1MHalfOpenHiThresh
Module: ZTE-AN-SECURITY-L3-MIB
OID (symbolic): ZTE-AN-SECURITY-L3-MIB::zxAnSecL3TcpC1MHalfOpenHiThresh
OID (numeric): 1.3.6.1.4.1.3902.1082.70.37.2.3.1.1.8
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: TCP half-open connections highest ratio threshold between zxAnSecL3TcpC1MHalfOpenConns and zxAnSecL3TcpC1MTotalConns in current 1 minute.
What is zxAnSecL3TcpC1MHalfOpenHiThresh?
This read-write percentage sets the upper threshold, evaluated over the current 1-minute window, above which the 1-minute half-open connection ratio contributes to pushing zxAnSecL3TcpSynFldProtectStatus into defence(3). Admins lower it to make the device react faster to a rapidly developing SYN flood observed within the most recent minute. For example, lowering zxAnSecL3TcpC1MHalfOpenHiThresh from the default 80% causes the device to enter defence mode sooner in response to a short, intense burst of half-open connections.
