The following table describes the information displayed after you type a section command.

From the 

::sonet=>

 prompt, type the line command in the following format then press 

. 

line [<port>] [-far] [-interval (<number>|all)]

Port

The OC3 line card slot and port to which the row of statistics applies.

Status

The current status of the specified port. Options:

NoDefect

—

There are no errors on the SONET Section layer.

LOS

—

There is a Loss Of Signal on the SONET Section layer.

LOF

—

There is a Loss Of Frame on the SONET Section layer.

ESs

The number of errored seconds in the 15-minute reporting interval. Errored seconds 
are seconds during which at least one Section layer bipolar error was detected or a 
severely errored frame or loss of signal error was present.

SESs

The number of severely errored seconds in the 15-minute reporting interval. Severely 
errored seconds are seconds during which 2,500 or more Section layer bipolar errors 
were detected or a severely errored frame or loss of signal error was present.

SEFSs

The number of severely errored framing seconds in the 15-minute reporting interval. 
Severely errored framing seconds are seconds during which the incoming signal has 
a minimum of four consecutive errored framing patterns.

CVs

The number of coding violations in the 15-minute reporting interval. Coding violations 
are the number of bipolar errors detected at the Section layer.

Interval

The 15-minute reporting interval for which the statistics are reported. This column 
only displays if you specify an interval in the command line.
