(Optional) Disabling the Log Counter Function

Logs generated on the switch contain sequence numbers. That is, the log counter function is enabled by default. For example, you can run the display logbuffer command to view the sequence numbers of logs.

If the Switch has been running for a long time, many logs may be generated.

• To enable the Switch not to encapsulate sequence numbers in logs sent to the log buffer, log file, console, or terminal, disable the log counter function.
• To re-collect statistics on logs sent to the log buffer, log file, console, or terminal, disable the log counter function, and then enable the log counter function.
• To view logs sent to the log buffer, log file, console, or terminal, disable the log counter function, enable the log counter function so that logs contain sequence numbers in ascending order.

• If logs are sent to the console, log file, or terminal, logs are counted independently and sequence numbers in the logs are in ascending order. That is, the sequence number of the log that was generated first is 0 and the log that is generated later has a larger sequence number.

• If logs are sent to the log buffer, sequence numbers in logs are in descending order. That is, the sequence number in the log that is generated recently is 0 and the log that was generated earlier has a larger sequence number.
