Log buffer size | Enter the maximum number (1~1024) of log messages that were |
| generated by ARP packets and have not been sent to the syslog |
| server yet. Make sure this number is appropriate for the specified |
| Syslog rate and Log interval. |
| 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. Click Clearing log status table in the ARP |
| Inspection Log Status screen to clear the log and reset this |
| counter. See Section 26.6.2 on page 253. |
