■
Example
host1(config-controll)# path 2 overhead c2 20
■
Use the no version to restore the default setting, in which the value of the C2
byte is determined by the layers configured above the SONET/SDH interface.
■
See path overhead c2.
path shutdown
■
Use to disable a specified path.
■
Paths are enabled by default.
■
Example
host1(config-controll)# path 2 shutdown
■
Use the no version to restart a disabled path.
■
See path shutdown.
path snmp trap link-status
■
Use to enable SNMP link status processing for the path layer of the interface.
■
The default is disabled.
■
Example
host1(config-controll)# path 2 snmp trap link-status
■
Use the no version to disable SNMP link status processing.
■
See path snmp trap link-status.
path trigger alarm prdi
■
Use to configure the router to use remote defect indications (RDIs) at the path
layer to determine the operational status of a path.
■
Example
host1(config-controll)# path 2 trigger alarm prdi
■
Use the no version to restore the default setting, in which the software uses loss
of pointer and AIS defects at the path layer to determine the operational status
of a path.
■
See path trigger alarm prdi.
path trigger delay
■
Use to set the time duration after which the router sets an alarm when it records
a defect at the path layer.
■
Change this value from the default only when you are using MPLS fast reroute
over a SONET/SDH interface.
