Syslog

This section provides information about the Syslog feature.

Overview

Syslog:

Allows you to store system messages and/or errors

Can store to local files on the switch or a remote server running a syslog daemon

Method of collecting message logs from many systems

Persistent Log Files

Currently three - one for each of the last three sessions

Each log has two parts:

Start up log is the first 32 messages after system startup

Operational log is the last 32 messages received after the startup log is full

Files are stored in ASCII format

slog0.txt - slog2.txt

olog0.txt - olog2.txt

Where 0 is for the boot, 1 is for the last boot, 2 is for the boot before that, and the third one falls off.

Can be saved to local server to monitor at a later point in time
