Description: TN ARP Inspection port mode for every port.

What is tnARPInspectionPortMode?

This per-port enumerated value, indexed by ifIndex in the tnARPInspectionPortModeTable, enables or disables ARP Inspection specifically on that port. Admins use it to apply the feature selectively — for instance enabling inspection on untrusted access ports facing end users while leaving trusted uplink ports disabled. For example, setting this to enable(1) on a port connected to a DHCP client segment would cause incoming ARP packets on that port to be checked against the inspection tables.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.1.22.2.1.1
snmpwalk -v2c -c public <target> TN-ARP-INSPECTION-MIB::tnARPInspectionPortMode

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.3.1.1.22.2.1.1.1
snmpget -v2c -c public <target> TN-ARP-INSPECTION-MIB::tnARPInspectionPortMode.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.868.2.5.3.1.1.22.2.1.1.1 i <value>
