chsonetexptrace
chsonetexptrace
Change expected path trace parameters for SONET lines.
chsonetexptrace Location [numOfLines expTraceIdLen expTraceId expTraceIdPosition]
Syntax Description
Defaults numOfLines: 1
Command Modes Security level 3
Command History
Usage Guidelines Use this command to configure the path trace parameters for SONET lines. This command works in
conjunction with the chsonettrace and chsonetperdi commands to configure a SONET line test.
Location The slot and line number, delimited by a period, of the OC-3 line.
Valid slot: 9. Valid lines: 1-4
numOfLines The number of lines to add. Values: 1-4.
expTraceIdLen The expected trace identifier length for the SONET path:
16=message contains 16 bytes (SDH only)
64=message contains 64 bytes (SONET or SDH)
expTraceId The expected trace identifier in the SONET path overhead. Value: ASCII
string of either 16 or 62 characters, depending on the TraceIdLen setting.
You specify the ASCII characters as pairs of hexidecimal characters. For
example, a you express a space as 20.
Note 1: The 16 byte message normally alters one byte for synchronization,
as defined by TraceIdPosition.
Note 2: The 64 byte message uses the last two bytes for synchronization, so
the maximum trace identifier length is 62 ASCII characters. Only printable
ASCII characters are allowed.
expTraceIdPosition The position within a 16-byte message of the synchronization byte. The
most significant bit of this byte is set high. Values: 1-16.
Alternatively, this parameter defines the following special cases:
0=No bit set
17=All most significant bits set low
