The switch maintains 1,000 messages in its internal log. You can display a snapshot of 
the log at any time by using the command

show log {<priority>} {<subsystem>}

where the following is true:

priority

 — Filters the log to display message with the selected priority or higher 

(more critical). Priorities include critical, warning, and informational. If not specified, 
informational priority messages and higher are displayed.

subsystem

 — Filters the log to display messages associated with the selected switch 

subsystem. Subsystems include Syst, STP Brdg, SNMP, Telnet, VLAN, and Port. If 
not specified, all subsystems are displayed.

In addition to viewing a snapshot of the switch log, you can configure the switch to 
maintain a running real-time display of log messages on the console. To turn on the log 
display, enter the following command:

To configure the log display, use the following command:

config log display {<priority>} {<subsystem>}

If 

priority

 is not specified, only messages of critical priority are displayed. If the 

subsystem

 is not specified, all subsystems are displayed.

If you enable the log display on a terminal connected to the console port, your settings 
will remain in effect even after your console session is ended (unless you explicitly 
disable the log display).

When using a Telnet connection, if your Telnet session is disconnected (because of the 
inactivity timer, or for other reasons), the log display is automatically halted. You must 
restart the log display by using the 

enable log display

 command.
