1672 ExtremeWare Software 7.3.0 Command Reference Guide
PoS Commands
configure sonet trace section ports
configure sonet trace section [<id_byte> | string <id_string>]
ports
<portlist>
Description
Configures the section trace identifier for the specified SONET ports.
Syntax Description
Default
The default is 1 for SONET, null for SDH.
Usage Guidelines
Section trace is a maintenance feature of SONET. One byte of the section overhead associated with each
SONET frame is used to carry information identifying the transmitting equipment. The section trace
identifier has two forms: an
id_byte
and an
id_string
. The
id_byte
parameter is an integer in the
range [0-255], with a default value of 1. The
id_string
parameter is a string that may contain up to 15
characters. By default,
id_string
contains 15 NULL characters. The
id_byte
parameter is only
applicable when SONET framing is configured. In this case, the configured
id_byte
value is
transmitted in each SONET frame. Analogously, the
id_string
parameter is only applicable when SDH
framing is configured. SDH framing repetitively cycles through a 15-character string, sending one
character per frame. If the configured string is less than 15 characters, it is padded with NULL
characters.
Example
The following command example sets the section trace identifier to the string
1800wombat
for port 1 of

config sonet trace section string 1800wombat ports 8:1
