You cannot display the contents of the persistent log file on stackable or standalone switches. Use
the show logging buffer command to show the most recent entries.
Procedure 1 Configuring a Server and Console Logging
Step Task Command(s)
1. Configure Syslog server 1 and accept default
settings (listed in Table 4 on page 8).
set logging server 1 ip-addr
10.1.1.2 state enable
2. (Optional) Verify that application logging settings
are at default values for the enabled server.
show logging application all
3. Enable console logging and disable file storage. set logging local console enable
file disable
Note: The set logging local command requires that you specify both console and file settings. For
example, set logging local console enable would not execute without also specifying file enable
or disable.
