Context config>port>sonet-sdh
Description This command configures the line signal (b2) degradation bit error rate (BER) and line signal failure
thresholds.
Alarms are raised if the line signal bit interleaved parity error rates exceed either the degradation or
failure thresholds. If the failure threshold is crossed, the link will be set to operationally down.
The no form of this command reverts to the default value.
Default threshold ber-sf 6 —
threshold ber-sf 3 —
Parameters ber-sd — specifies the BER for signal degradation
ber-sf — specifies the BER for signal failure
rate threshold-rate — specifies the BER negative exponent (n in 10
