zxAnSecL3TcpHalfOpenLoThresh
Module: ZTE-AN-SECURITY-L3-MIB
OID (symbolic): ZTE-AN-SECURITY-L3-MIB::zxAnSecL3TcpHalfOpenLoThresh
OID (numeric): 1.3.6.1.4.1.3902.1082.70.37.2.3.1.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: TCP half-open connections lowest ratio threshold between zxAnSecL3TcpHalfOpenConns and zxAnSecL3TcpTotalConns.
What is zxAnSecL3TcpHalfOpenLoThresh?
This read-write percentage sets the lower threshold for the ratio of half-open to total TCP connections, below which zxAnSecL3TcpSynFldProtectStatus is considered safety(1). Admins tune it to define the boundary between normal traffic and early signs of a developing SYN flood. For example, lowering zxAnSecL3TcpHalfOpenLoThresh below the default 60% makes the device treat a smaller proportion of half-open connections as still within the safe range.
Examples
Walk all instances (SNMPv2c):
