Monitoring SONET/SDH Interfaces
defect trigger soaking delay Time that the router waits to set an alarm
when the router records a defect at the section or line layer
Operational Status Physical state of the interface:
up Interface is operational
down, failure alarm Interface is not operational; type of defect that
caused failure is specified
time since last status change Time since the module was rebooted
Loopback State Type of loopback configured on the interface
Mode Type of interface: SONET or SDH
Timing source Type of clock source configured for the channel:
line Internal clock is from the line module itself
chassis Internal clock is from the configured router clock
Receive FIFO Overruns Number of times received FIFO was overrun
Current section defects Number of suspect bit patterns found in several
consecutive frames in section layer
Current line defects Number of suspect bit patterns found in several
consecutive frames in line layer
Received SONET overhead Section and line overhead bytes present in the
receive side of the interface at any particular time
Transmitted SONET overhead Section and line overhead bytes present in
the transmit side of the interface at any particular time
Channel configuration Parameters for specific controllers. The actual
parameters depend on the controller.
ifAdminStatus State of the controller in the software configuration: up
or down
snmp trap link-status State of SNMP link status processing for the path
layer: enabled or disabled
alarms used for operational status calculation Types of defects that the
router uses to determine the operational status of the interface at the
path layer
defect trigger soaking delay Time that the router waits to set an alarm
when the router records a defect at the path layer
c2 byte Setting of path signal byte: set by upper interface type
(automatic setting) or configured value
