Configuration Tasks
Step 10
path keyword [values]
Example:
RP/0/0/CPU0:router(config-sonet)# path delay
trigger 25
(Optional) Configures SONET controller path values.
Keyword definitions are as follows:
• ais-shut—Sets sending path alarm indication signal
(PAIS) when shut down.
• delay trigger—Sets SONET path delay trigger value,
which can be 0–511 milliseconds (default 0).
• overhead—Sets SONET POH byte or bit values where
c2 specifies STS synchronous payload envelope (SPE)
content (C2) byte, and j1 configures the SONET path
trace (J1) buffer.
• report—Sets SONET path alarm reporting. Specifies
which alarms are reported and which bit error rate
(BER) thresholds will signal an alarm. The following
keywords can be used:
– b3-tca sets B3 BER threshold crossing alert (TCA)
reporting status
– pais sets PAIS reporting status
– plop sets path loss of pointer reporting status
– prdi sets path remote defect indication reporting
status
– puneq sets path unequipped defect indication
reporting status
• scrambling—Disables SPE scrambling with keyword
disable.
• threshold—Sets SONET path BER threshold value to
3–9; bit error rate (10 to the minus x) (where the default is
6).
• uneq-shut—Sets sending unequipped (UNEQ) when
shut down.
