Information About Switch Alarms
Note You can associate multiple alarms to one relay or one alarm to both relays.
Table 5-2 lists the port status monitoring alarms and their descriptions and functions. Each fault
condition is assigned a severity level based on the Cisco IOS System Error Message Severity Level.
Triggering Alarm Options
The switch supports these methods for triggering alarms:
• Configurable Relay
The switch is equipped with one independent alarm relay that can be triggered by alarms for global
and port status conditions. You can configure the relay 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
the alarm relay. Each fault condition is assigned a severity level based on the Cisco IOS System
Error Message Severity Level.
See the “Configuring Switch Alarms” section on page 5-7 for more information on configuring the
relay.
• 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 changed so that the user can 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 5-12 for more
information.

Table 5-2 Switch Port Status Monitoring Alarms
Alarm Description
Link Fault alarm The switch generates a link fault alarm when problems with a port physical
layer cause unreliable data transmission. A typical link fault condition is loss
of signal or clock. The link fault alarm is cleared automatically when the link
fault condition is cleared. The severity for this alarm is error condition, level
3.
Port not Forwarding
alarm
The switch generates a port not forwarding alarm when a port is not
forwarding packets. This alarm is cleared automatically when the port begins
to forward packets. The severity for this alarm is warning, level 4.
Port not Operating
alarm
The switch generates a port not operating alarm when a port fails during the
startup self-test. When triggered, the port not-operating alarm is only cleared
when the switch is restarted and the port is operational. The severity for this
alarm is error condition, level 3.
FCS Bit Error Rate
alarm
The switch generates an FCS bit error rate alarm when the actual FCS bit
error rate is close to the configured rate. You can set the FCS bit error rate by
using the interface configuration CLI for each of the ports. See the
“Configuring the FCS Bit Error Rate Alarm” section on page 5-8 for more
information. The severity for this alarm is error condition, level 3.
