322001: Deny MAC address
Cisco ASA is a security device that provides the combined capabilities of a firewall, an antivirus, and an intrusion prevention system. It also facilitates virtual private network (VPN) connections. It helps to detect threats and stop attacks before they spread through the network.
Message: %ASA-3-322001: Deny MAC address MAC_address, possible spoof attempt on interface interface.
Event 322001 is generated when the ASA receives a packet from an offending MAC address on a specified interface, but the source MAC address in the packet is statically bound to another interface in the configuration. This could possibly be caused by a MAC spoofing attack or a misconfiguration.
How could you resolve this situation?
Check the configuration and take appropriate action by either finding the offending host or correcting the configuration.
