ctAgentDaiDstMacValidate
Module: CT-FASTPATH-DYNAMIC-ARP-INSPECTION-MIB
OID (symbolic): CT-FASTPATH-DYNAMIC-ARP-INSPECTION-MIB::ctAgentDaiDstMacValidate
OID (numeric): 1.3.6.1.4.1.52.4.2.36.1.1.2
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object indicates whether Target MAC validation in the ARP Response packets is enabled.
If this object is set to 'true', validation is enabled.
If this object is set to 'false', validation is disabled.
What is ctAgentDaiDstMacValidate?
This read-write TruthValue enables or disables validation that the target MAC address inside an ARP response packet's payload matches the destination MAC address in its Ethernet header. An administrator enables this globally to catch spoofed ARP replies that misrepresent their intended recipient. For example, enabling ctAgentDaiDstMacValidate would cause DAI to drop an ARP reply whose Ethernet destination MAC doesn't match the target MAC field claimed inside the packet.
