time. The first [dec] is the ASIC, and the second [dec] is the queue number.
Recommended Action Copy the message exactly as it appears on the console or in the system log.
Research and attempt to resolve the error by using the Output Interpreter. Use the Bug Toolkit to
look for similar reported problems. If you still require assistance, contact HP technical support and

SW_DAI Messages
This section contains the dynamic ARP inspection (DAI) messages.
Error Message SW_DAI-4-ACL_DENY: [dec] Invalid ARPs ([chars]) on [chars], vlan
[dec].([[enet]/[chars]/[enet]/[chars]/[time-of-day]]).
Explanation
The switch has received ARP packets considered invalid by ARP inspection. The
packets are erroneous, and their presence shows that administratively denied packets were seen in
the network. This log message appears when packets have been denied by ACLs either explicitly or
implicitly (with static ACL configuration). These packets show attempted man-in-the-middle
attacks in the network. The first [dec] is the number of invalid ARP packets. The first [chars] is either
Req (request) or Res (response), and the second [chars] is the short name of the ingress interface.
The second [dec] is the ingress VLAN ID. [enet]/[chars]/[enet]/[chars]/[time-of-day] is the MAC
address of the sender, the IP address of the sender, the MAC address of the target, the IP address of
the target, and the time of day.
Recommended Action No action is required.
Error Message SW_DAI-4-DHCP_SNOOPING_DENY: [dec] Invalid ARPs ([chars]) on [chars],
vlan [dec].([[enet]/[chars]/[enet]/[chars]/[time-of-day]]).
Explanation
The switch has received ARP packets considered invalid by ARP inspection. The
packets are erroneous, and their presence might show attempted man-in-the-middle attacks in the
network. This log message appears when the sender’s IP and MAC address binding for the received
VLAN is not present in the DHCP snooping database. The first [dec] is the number of invalid ARP
packets. The first [chars] is either Req (request) or Res (response), and the second [chars] is the short
name of the ingress interface. The second [dec] is the ingress VLAN ID.
[enet]/[chars]/[enet]/[chars]/[time-of-day] is the MAC address of the sender, the IP address of the
sender, the MAC address of the target, the IP address of the target, and the time of day.
Recommended Action No action is required.
