Configuring Catalyst 2955 Switch Alarms
Triggering Alarm Options
The Catalyst 2955 supports three methods for triggering alarms:
• Configurable Relays
The Catalyst 2955 switch is equipped with two independent alarm relays that can be triggered by
alarms for global and port status conditions. The relays can be configured to send a fault signal to
an external alarm device, such as a bell, light, or other signaling device. You can associate any alarm
condition with either alarm relay or both relays. Each fault condition is assigned a severity level
based on the Cisco IOS System Error Message Severity Level.
See the “Configuring Catalyst 2955 Switch Alarms” section on page 3-4 for more information on
configuring the relays.
• SNMP Traps
SNMP is an application-layer protocol that provides a message format for communication between
managers and agents. The SNMP system consists of an SNMP manager, an SNMP agent, and a
management information base (MIB).
The snmp-server enable traps command can be modified in the Catalyst 2955 switch software to
allow the user to send alarm traps to an SNMP server. You can use alarm profiles to set
environmental or port status alarm conditions to send SNMP alarm traps. See the “Enabling SNMP
Traps” section on page 3-12 for more information.
• Syslog Messages
You can use alarm profiles to send system messages to a syslog server. See the “Configuring
Catalyst 2955 Switch Alarms” section on page 3-4 for more information.
