Configuring Catalyst 2955 Switch Alarms
Note Before you can use the notifies command to send alarm traps to an SNMP server, you must first set up
the SNMP server by using the snmp-server enable traps alarms global configuration command. See
the “Enabling SNMP Traps” section on page 3-12.
Use the no alarm facility temperature secondary to disable the secondary temperature alarm.
This example sets the secondary temperature alarm to the minor relay, with a lower high temperature
threshold value of 45
o
C. All alarm and traps associated with this alarm will be sent to a syslog server
and an SNMP server.
Switch(config) # alarm facility temperature secondary 45
Switch(config) # alarm facility temperature secondary relay minor
Switch(config) # alarm facility temperature secondary syslog
Switch(config) # alarm facility temperature secondary notifies
This example sets the first (primary) temperature alarm to the major relay. All alarms and traps
associated with this alarm will be sent to a syslog server.
Switch(config) # alarm facility temperature primary syslog
Switch(config) # alarm facility temperature primary relay major
Configuring the FCS Bit Error Rate Alarm
This section describes how to configure the FCS bit error rate alarm on your switch:
• Setting the FCS Error Threshold, page 3-8
• Setting the FCS Error Hysteresis Threshold, page 3-9
Setting the FCS Error Threshold
The switch generates an FCS bit error rate alarm when the actual FCS bit error rate is close to the
configured FCS bit error rate. Use the fcs-threshold interface configuration command to set the FCS
error threshold.
Beginning in privileged EXEC mode, follow these steps to set the bit error rate value for a port:
Step 5
end Return to privileged EXEC mode.
Step 6
show alarm settings Verify the configuration.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter the number of the switch port to be configured, and the switch enters
interface configuration mode.
Step 3
fcs-threshold value Set the FCS error rate.
For value, the range is 6 to 11 to set a maximum bit error rate of 10
-6
to 10
-11
.
By default, the FCS bit error rate is 10
-8
