SW_DAI Messages
Error Message
SW_DAI-4-PACKET_RATE_EXCEEDED: [dec] packets received in [dec]
milliseconds on [chars].
Explanation
The switch has received the given number of ARP packets for the specified duration on
the interface. This message is logged just before the port is put into the error-disabled state because
of the exceeded packet rate and when the burst interval is set to 1 second. The first [dec] is the
number of packets, the second [dec] is the number of milliseconds, and [chars] is the affected
interface.
Recommended Action
No action is required.
Error Message
SW_DAI-4-SPECIAL_LOG_ENTRY: [dec] Invalid ARP packets [[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 message differs from other SW_DAI messages in that this message captures all
messages when the rate of incoming packets exceeds the dynamic ARP inspection logging rate.
[dec] is the number of invalid ARP packets, and [time-of-day] is the time of day.
Recommended Action
No action is required.
Error Message
SW_DAI-6-ACL_PERMIT: [dec] ARPs ([chars]) on [chars], vlan
[dec].([[enet]/[chars]/[enet]/[chars]/[time-of-day]]).
Explanation
The switch has received ARP packets that are permitted as a result of an ACL match.
The first [dec] is the number of valid 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-6-DHCP_SNOOPING_PERMIT: [dec] ARPs ([chars]) on [chars], vlan
[dec].([[enet]/[chars]/[enet]/[chars]/[time-of-day]]).
Explanation
The switch has received ARP packets that have been permitted because the sender’s IP
and MAC address match the DHCP snooping database for the received VLAN. The first [dec] is the
number of valid 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.
