Description: The reason that the trap was generated. srcIpNotFound(1) indicates that the Sender IP address of the ARP packet was not found in the DHCP Snooping database. badVLAN(2) indicates that the VLAN of the DHCP Snooping binding entry associated with the Sender IP address of the ARP packet does not match the VLAN that the ARP packet was received on. badPort(3) indicates that the port of the DHCP Snooping binding entry associated with the Sender IP address of the ARP packet does not match the port that the ARP packet was received on. srcIpNotAllocated(4) indicates that the CHADDR of the DHCP Snooping binding entry associated with the Sender IP address of the ARP packet does not match the Source MAC and/or the ARP source MAC of the ARP packet.
What is atArpsecVioType?
This enumeration shows why ARP security triggered an alert (IP not found in DHCP bindings, VLAN mismatch, etc). It reports violation. A value of srcIpNotFound(1) means no DHCP binding.
