Example FTOS>show interfaces sonet 2/0
SONET 2/0 is up, line protocol is up
Hardware is SONET, address is 00:01:e8:00:03:ff
LINE
AIS
Displays the alarm indication signal.
This signal is sent by the section terminating equipment (STE) to alert the downstream line
terminating equipment (LTE) that a LOS or LOF defect has been detected on the incoming
interface section.
Path alarm indication signal is sent by the LTE to alert the downstream path terminating
equipment (PTE) that it has detected a defect on its incoming line signal.
RDI Displays remote defect indication.
This indication is reported by the downstream LTE when it detects LOF, LOS, or AIS conditions.
BIP(B2) Displays the bit interleaved parity error for the B2 byte.
For B2, the report is calculated by comparing the BIP-8/24 code with the BIP-8 code
extracted from the B2 byte of the following frame.Differences indicate line-level errors.
PATH
AIS
Displays the alarm indication signal.
This signal is sent by the section terminating equipment (STE) to alert the downstream line
terminating equipment (LTE) that a LOS or LOF defect has been detected on the incoming
SONET section.
Path alarm indication signal is sent by the LTE to alert the downstream path terminating
equipment (PTE) that it has detected a defect on its incoming line signal.
RDI Displays remote defect indication.
This indication is reported by the downstream LTE when it detects LOF, LOS, or AIS conditions.
BIP(B3) Displays the bit interleaved parity error for the B3 byte.
For B3, the bit interleaved parity error report is calculated by comparing the BIP-8 code with
the BIP-8 code extracted from the B3 byte of the following frame. Differences indicate
path-level errors.
Active Defects: Lists the current interface defects.
Active Alarms List the current interface alarms as enforced the interface Alarm Hierarchy.
Alarm reporting
enabled for:
List the alarms enabled. Enabled alarms generate trap reports.
