aps unidirectional
threshold

You can issue this command only for the protect interface, not for the working interface.
Example
host1(config-controll)#aps revert 7
Use the no version to restore the default setting, in which the router does not revert to
the working interface when it recovers.
See aps revert.
Use to specify that the router should switch to the protect interface using the
unidirectional mode switching mechanism.
You can issue this command only for the protect interface, not for the working interface.
Example
host1(config-controller)#aps unidirectional
Use the no version to restore the default setting, bidirectional mode.
See aps unidirectional.
Configuring SONET/SDH Alarms
To configure the bit error rates that determine signal degradation and signal failure on
the working interface:
Select the protect interface.
1.
host1(config)#controller sonet 4/1
Specify the bit error rate at which the router should generate an alarm indicating signal
2.
degradation.
host1(config-controller)#threshold sd-ber 6
Specify the bit error rate at which the router should generate an alarm indicating signal
3.
failure and switch from the working interface to the protect interface.
host1(config-controller)#threshold sf-ber 5
Use to set thresholds for the bit error rates associated with APS/MSP alarms.
You can issue this command only for the protect interface. It does not apply to the
working interface.
Specify one of the following keywords to indicate the alarm level:
sd-ber—Bit error rate that specifies signal degradation
sf-ber—Bit error rate that specifies signal failure
Specify an integer n in one of the following ranges, where n corresponds to a rate of
10-n (10e-n) errors per second.
For sd-ber, an integer in the range 5–9; the default value is 5
