OID (symbolic): ZTE-AN-SECURITY-L3-MIB::zxAnSecL3TcpC1MHalfOpenConns
OID (numeric): 1.3.6.1.4.1.3902.1082.70.37.2.3.1.1.24
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Number of TCP half-open connections that cannot be established in current 1 minute.
What is zxAnSecL3TcpC1MHalfOpenConns?
This read-only counter reports the number of TCP half-open connections observed within the current 1-minute measurement window that have not completed their handshake. Admins monitor it as the short-window companion to zxAnSecL3TcpHalfOpenConns, giving faster detection of a SYN-flood burst than the longer-running overall counter. For example, a sharp jump in zxAnSecL3TcpC1MHalfOpenConns during a single minute would trigger the device's defence(3) status faster than waiting for the overall half-open counter to climb.
