zyAntiArpscanPortThreshold
Module: ZYXEL-ANTI-ARPSCAN-MIB
OID (symbolic): ZYXEL-ANTI-ARPSCAN-MIB::zyAntiArpscanPortThreshold
OID (numeric): 1.3.6.1.4.1.890.1.15.3.106.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Set the threshold (2-255) of received ARP messages for the port-based Anti-Arpscan.
What is zyAntiArpscanPortThreshold?
Sets the threshold number of received ARP messages that triggers the port-based Anti-ARP-scan protection. Admins tune this to control sensitivity - a lower threshold catches ARP scanning faster but risks false positives from legitimate bursty ARP traffic, while a higher one reduces false positives but reacts more slowly to real scans. Setting zyAntiArpscanPortThreshold to 50 means a port that receives 50 or more ARP messages within the detection window triggers the port-based protection response.
Examples
Walk all instances (SNMPv2c):
