Chapter 3 Configuring Catalyst 2955 Switch Alarms
Configuring Catalyst 2955 Switch Alarms
• 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 3-11 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.
