show interfaces transport pm

Syntax

Description

Display diagnostic data, warnings, and alarms for transport performance monitoring interfaces.

Options

all Display information about both optics and OTN
optics Display information only about optics
otn Display information only about OTN
all Display information for the current 15-minute interval, the current day, the ninety-six 15-minute intervals, and the previous day.
current Display information only for the current 15-minute interval.
currentday Display information only for the current 24 hours
interval Display information only for the ninety-six 15-minute intervals
previousday Display information only for the previous day.

(all | interface-name)—Display information for all interfaces or only for the specified interface (for example, et-fpc/pic/port).

Output Fields

Table 1 lists the output fields for the show interfaces transport pm optics command. Fields are listed in the approximate order in which they appear.

Table 1: show interfaces transport pm Output Fields

Field Name

Field Description

Physical interface

Name of the physical interface.

Interval

The 15 minute interval for performance monitoring.

TRUE if the performance monitoring data for the interval appears to be inaccurate.

Reason

Reason for setting the suspect flag.

COUNT

Measured value.

THRESHOLD

Threshold value set.

TCA-ENABLED

Threshold crossing alert. Set to TRUE if enabled.

TCA-RAISED

TRUE if enabled and the value crosses the threshold.

Near End PM

Near end threshold crossing defect trigger. For more information about each trigger, see tca.

Far End PM

Far end threshold crossing defect trigger. For more information about each trigger, see tca.

FEC PM

Forwarding equivalence class threshold crossing defect trigger. For more information about each trigger, see tca.

BER PM

Bit error rate threshold crossing defect trigger. For more information about each trigger, see tca.

CURRENT

Current value measured.
