Release Information

Statement introduced in JUNOS Release 8.5.


Minor alarm error thresholds for T1 CRC errors. When the threshold is exceeded for one second, a defect condition is declared. If the defect condition continues for the monitoring period, an alarm condition is declared.


10-second monitoring period for values 1e-3, 5e-4, 1e-4, and 5e-5. The 1e-5 value uses a 50-second monitoring period. The 5e-6 value uses a 100-second monitoring period. The 1e-6 value uses a 500-second monitoring period.


rate—Error rate expressed as the number of errors per number of bits. The value 1e-3 is one error in 10–3 bits and 5e-4 is five errors in 10–4 bits.

Default: 5e-6
