SW_DAI Messages
Error Message SW_DAI-6-DHCP_SNOOPING_PERMIT: [dec] ARPs ([chars]) on [chars], vlan
[dec].([[enet]/[chars]/[enet]/[chars]/[time-of-day]]).
Explanation
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
Error Message SW_DAI-4-INVALID_ARP: [dec] Invalid ARPs ([chars]) on [chars], vlan
[dec].([[enet]/[chars]/[enet]/[chars]/[time-of-day]]).
Explanation
ARP inspection. The packets do not pass one or more validation checks of the source or destination
MAC address or the IP address. The first [dec] is the number of invalid ARP packets. The first
[chars] is either Req (request), Res (response), or Invalid Opcode. 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
Error Message SW_DAI-4-PACKET_BURST_RATE_EXCEEDED: [dec] packets received in [dec]
seconds on [chars].
Explanation
the specified burst interval. The interface is in the error-disabled state when the switch receives
packets at a higher rate than the configured packet rate every second over the configured burst
interval. The message is logged just before the interface is error disabled and if the configured burst
interval is more than a second. The first [dec] is the number of packets, the second [dec] is the
number of seconds, and [chars] is the affected interface.
Recommended Action
Error Message SW_DAI-4-PACKET_RATE_EXCEEDED: [dec] packets received in [dec]
milliseconds on [chars].
Explanation
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.
