What is agentSwitchDenialOfServiceSMACDMACMode?

This read-write switch enables or disables the "SMAC=DMAC" Denial-of-Service protection feature, which targets frames whose source MAC address matches their destination MAC address. Admins turn this on to block a Layer 2 analogue of the SIP=DIP spoofing attack, since a frame claiming to be sent from and to the same MAC address is invalid and often used to confuse network stacks. For example, enabling this feature on an access switch causes it to drop a crafted frame where both the source and destination MAC fields are set to the same address, rather than passing it upstream.

Examples
