DESCRIPTION
This field displays the maximum number (1-1024) of log messages that
were generated by ARP packets and have not been sent to the syslog
server yet.
If the number of log messages in the Switch exceeds this number, the
Switch stops recording log messages and simply starts counting the
number of entries that were dropped due to unavailable buffer.
This field displays the maximum number of syslog messages the Switch
can send to the syslog server in one batch. This number is expressed as a
rate because the batch frequency is determined by the Log Interval.
This field displays the source port of the ARP packet.
This field displays the source VLAN ID of the ARP packet.
This field displays the source MAC address of the ARP packet.
This field displays the source IP address of the ARP packet.
This field displays the number of ARP packets that were consolidated into
this log message. The Switch consolidates identical log messages
generated by ARP packets in the log consolidation interval into one log
message.
This field displays the reason the log message was generated.
dhcp deny: An ARP packet was discarded because it violated a dynamic
binding with the same MAC address and VLAN ID.
static deny: An ARP packet was discarded because it violated a static
binding with the same MAC address and VLAN ID.
deny: An ARP packet was discarded because there were no bindings with
the same MAC address and VLAN ID.
static permit: An ARP packet was forwarded because it matched a static
binding.
dhcp permit: An ARP packet was forwarded because it matched a
dynamic binding.
This field displays when the log message was generated.
This field displays the number of log messages that were generated by
ARP packets and that have not been sent to the syslog server yet. If one or
more log messages are dropped due to unavailable buffer, there is an entry
called overflow with the current number of dropped log messages.
