The following table describes the labels in this screen.
Table 58 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 21.5 on page 164. |
|
|
Reason | This field displays the reason the log message was generated. |
| 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. |
| 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 21.5.2 |
| |
|
|
Time | This field displays when the log message was generated. |
