Juniper JUNOSE 11.2.X MULTICAST ROUTING, Configuration Manual

Page: 112 / 256

•
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.
aps unidirectional
•
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:
1.
Select the protect interface.
host1(config)# controller sonet 4/1
2.
Specify the bit error rate at which the router should generate an alarm indicating
signal degradation.
host1(config-controller)# threshold sd-ber 6
3.
Specify the bit error rate at which the router should generate an alarm indicating
signal failure and switch from the working interface to the protect interface.
host1(config-controller)# threshold sf-ber 5
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
