Command Usage
The command specifies the facility type tag sent in syslog messages. (See RFC
3164.) This type has no effect on the kind of messages reported by the switch.
However, it may be used by the syslog server to sort messages or to store messages
in the corresponding database.
Example
Console(config)#logging facility 19
Console(config)#
logging history This command limits syslog messages saved to switch memory based on severity.
