tnARPInspectionMode
Module: TN-ARP-INSPECTION-MIB
OID (symbolic): TN-ARP-INSPECTION-MIB::tnARPInspectionMode
OID (numeric): 1.3.6.1.4.1.868.2.5.3.1.1.22.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: TN ARP Inspection Mode on a device.
What is tnARPInspectionMode?
This read-write enumerated value turns ARP Inspection on or off for the entire device, with enable(1) and disable(2) as its only settings. An admin uses it as the master switch for the ARP anti-spoofing feature before configuring any per-port or static/dynamic ARP inspection entries, since those only take effect once this global mode is enabled. For example, a network engineer securing an access-layer switch against ARP poisoning would set this to enable(1) first, then build out the static and dynamic inspection tables.
