Understanding Catalyst 2955 Switch Alarms

The Catalyst 2955 switch software monitors switch conditions on a per port or a switch basis. If the
conditions present on the switch or port do not match the parameters set by the user, the switch software
triggers an alarm or a system message. By default, the switch software sends the system messages to a
system message logging facility, or a syslog facility. You can also configure the switch to send Simple
Network Management Protocol (SNMP) traps to an SNMP server. You can configure the switch to
trigger an external alarm device by using the two independent alarm relays (major or minor). For more
information on how to configure the alarms, see the “Configuring Catalyst 2955 Switch Alarms” section
on page 3-4.
