Chapter 25 IP Source Guard Figure 155 Advanced Application > IP Source Guard > ARP Inspection > Log Status The following table describes the labels in this screen. Table 98 Advanced Application > IP Source Guard > ARP Inspection > Log Status LABEL Clearing log status table Total number of logs Index Port VID Sender MAC Sender IP Num Pkts Reason DESCRIPTION Click Apply to remove all the log messages that were generated by ARP packets and that have not been sent to the syslog server yet. 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. This field displays a sequential number for each log message. 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. You can configure this interval in the ARP Inspection Configure screen. See Section 25.9 on page 215. 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. dhcp permit: An ARP packet was forwarded because it matched a dynamic binding. static permit: An ARP packet was forwarded because it matched a static binding. Time In the ARP Inspection VLAN Configure screen, you can configure the Switch to generate log messages when ARP packets are discarded or forwarded based on the VLAN ID of the ARP packet. See Section 25.9.2 on page 218. This field displays when the log message was generated. GS1920 Series User's Guide 214

Advanced Application > IP Source Guard > ARP Inspection > Log Status
LABEL
DESCRIPTION
Clearing log status
table
Click
Apply
to remove all the log messages that were generated by ARP packets and
that have not been sent to the syslog server yet.
Total number of logs
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.
Index
This field displays a sequential number for each log message.
Port
This field displays the source port of the ARP packet.
VID
This field displays the source VLAN ID of the ARP packet.
Sender MAC
This field displays the source MAC address of the ARP packet.
Sender IP
This field displays the source IP address of the ARP packet.
Num Pkts
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. You can configure this interval
in the
ARP Inspection Configure
screen.
See Section 25.9 on page 215.
Reason
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.
dhcp permit
: An ARP packet was forwarded because it matched a dynamic binding.
static permit
: An ARP packet was forwarded because it matched a static binding.
In the
ARP Inspection VLAN Configure
screen, you can configure the Switch to
generate log messages when ARP packets are discarded or forwarded based on the
VLAN ID of the ARP packet.
See Section 25.9.2 on page 218.
Time
This field displays when the log message was generated.
