The FCS hysteresis threshold is applied to all ports on the switch. The allowable range is from 1 to 10 percent. The default
value is 10 percent. See Configuring the FCS Bit Error Rate Alarm, page 52 for more information.
Port Status Monitoring Alarms
The switch can also monitor the status of the Ethernet ports and generate alarm messages based on the alarms listed in
Table 11 on page 50. To save user time and effort, it supports changeable alarm configurations by using alarm profiles.
You can create a number of profiles and assign one of these profiles to each Ethernet port.
Alarm profiles provide a mechanism for you to enable or disable 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 11 on page 50 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 Configuring the Power Supply Alarms, page 51 for more information on configuring the relay.
 SNMP Traps
Table 11 Port Status Monitoring Alarms
Alarm List ID Alarm Description
1 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.
2 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.
3 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.
4 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 Configuring
the FCS Bit Error Rate Alarm, page 52 for more information. The severity for
this alarm is error condition, level 3.
