Chapter 3 Configuring Switch Alarms
Information About Switch Alarms
Alarm profiles provide a mechanism for you to enable or disabl e alarm conditions for a port and
associate the alarm conditions with one or both alarm relays. You can also use alarm profiles to set alarm
conditions to send alarm traps to an SNMP server and system messages to a syslog server. The alarm
profile defaultPort is applied to all interfaces in the factory configuration (by default).
Note You can associate multiple alarms to one relay or one alarm to both relays.
Table 3-2 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,
port status and SD flash card 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 the Power Supply Alarms” section on page 3-6 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).
Tab l e 3-2 Port Status Monitoring Alarms
Alarm List ID Alarm Description
1Link 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.
2Port not Forwarding alarm The switch generates a port not-forwarding alarm when a po rt 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.
3Port 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.
4FCS 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 3-7 for more
information. The severity for this alarm is error condition, level 3.
