zyAntiArpscanHostThreshold
Module: ZYXEL-ANTI-ARPSCAN-MIB
OID (symbolic): ZYXEL-ANTI-ARPSCAN-MIB::zyAntiArpscanHostThreshold
OID (numeric): 1.3.6.1.4.1.890.1.15.3.106.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Set the threshold (2-100) of received ARP messages for the host-based Anti-Arpscan.
What is zyAntiArpscanHostThreshold?
Sets the threshold number of received ARP messages that triggers the host-based Anti-ARP-scan protection, tracked per source host rather than per port. Admins tune this separately from the port threshold since a single compromised host generating excessive ARP traffic behind a shared port might not trip the port threshold but should still be caught per-host. Setting zyAntiArpscanHostThreshold to 20 flags any individual host sending 20 or more ARP messages within the detection window, even if the port overall stays under its own threshold.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.106.1.3 snmpwalk -v2c -c public <target> ZYXEL-ANTI-ARPSCAN-MIB::zyAntiArpscanHostThreshold
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.890.1.15.3.106.1.3.1 snmpget -v2c -c public <target> ZYXEL-ANTI-ARPSCAN-MIB::zyAntiArpscanHostThreshold.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.890.1.15.3.106.1.3.1 i <value>
