# threshold

#### Syntax

threshold { sd-ber | sf-ber } rate

no threshold { sd-ber | sf-ber }

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Sets the threshold values for bit error rates used in APS/MSP alarms. This command applies only to the protect interface, and not to the working interface. The no version restores the default value, 5 (for the sd-ber bit error rate) or 3 (for the sf-ber bit error rate), for the specified alarm.

#### Options

- sd-ber—Bit error rate that specifies signal degradation
- sf-ber—Bit error rate that specifies signal failure
- rate—Integer n with available values depending on the bit error rate type you specify; a value of n corresponds to a rate of 10-n (10e-n) errors per second
  - For sd-ber, an integer in the range 5–9; default value is 5
  - For sf-ber, an integer in the range 3–5; default value is 3
