12-1: Logging
Logging is used by the switch to send system messages to a logging facility.
■
Logging messages can be sent to any of four different facilities: the switch console, a
■
file on the switch, Telnet sessions, or a syslog server.
Logging history can be maintained in a file to ensure that a record of the messages
■
sent to Simple Network Management Protocol (SNMP) or syslog servers are kept
in case a packet is lost or dropped.
