To disable logging of select SONET alarms, use the no form of this command.
Reporting an alarm means that the alarm can be logged to the console. Not all alarms are logged. SONET
alarm hierarchy rules dictate that only the most severe alarm of an alarm group is reported. Whether an
alarm is reported or not, you can view the current state of a defect by checking the Active Defects line
from the show controllers atm command output. A defect is a problem indication that is a candidate for
an alarm.
The following example shows how to enable reporting of SD-BER and LAIS alarms on the interface:
Router(config)# interface atm 3/0/0
Router(config-if)# atm report sd-ber
Router(config-if)# atm report lais
Router(config-if)# end
Router#

Specifying the ATM Alarm Thresholds

Specify the bit error rate (BER) threshold by using the atm threshold command:
atm threshold {b1-tca | b2-tca | b3-tca | sd-ber | sf-ber} value
Where:

The default for all thresholds, except sf-ber, is 10

b1-tca—B1 bit error rate (BEF) threshold crossing alarm
b2-tca—B2 BER threshold crossing alarm
b3-tca—B3 BER threshold crossing alarm
lais—Line Alarm Indication Signal
lcd—Loss of cell delineation
lrdi—Line Remote Defect Indication
pais—Path Alarm Indication Signal
plop—Path Loss of Pointer
prdi—Path Remote Defect Indication
rdool—Receive Data Out Of Lock
sd-ber—Line bit interleave parity error (LBIP) BER in excess of signal degrade (SD) threshold
sf-ber—LBIP BER in excess of signal fail (SF) threshold
slof—Section Loss of Frame
slos—Section Loss of Signal
b1-tca—B1 BER threshold crossing alarm
b2-tca—B2 BER threshold crossing alarm
b3-tca—B3 BER threshold crossing alarm
sd-ber—Set Signal Degrade BER threshold
sf-ber—Set Signal Fail BER threshold
value is an exponential value from 10

to 10 representing the BER at which an alarm occurs.
