threshold
■
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
■
For sf-ber , an integer in the range 3–5; the default value is 3
■
Example
host1(config-controll)# threshold sf-ber 4
■
Use the no version to restore the default, 5 (for sd-ber ) or 3 (for sf-ber ), for the
specified alarm.
■
See threshold.
Configuration Example
The following example shows how to configure working and protect interfaces for
APS/MSP.
1.
Configure the working interface.
host1(config)# controller sonet 3/0
host1(config-controller)# aps group boston
host1(config-controller)# aps working 1
2.
Configure the protect interface.
host1(config-controller)# controller sonet 3/1
host1(config-controller)# aps group boston
host1(config-controller)# aps protect 0
host1(config-controller)# aps unidirectional
host1(config-controller)# aps revert 30
host1(config-controller)# threshold sf-ber 4

To configure line modules to deliver APS events to the necessary SNMP traps, issue
the
aps events command from Global Configuration mode.
