2320 ExtremeWare 7.7 Command Reference Guide
PoS Commands—BlackDiamond Switch Only
configure sonet signal label ports
configure sonet signal label [auto | <hex_octet>] ports <portlist>
Description
Configures the signal label value for the specified SONET ports.
Syntax Description
Default
The default is
auto
, where the value of the signal Label field is automatically set based on standard
conventions for the given payload type.
Usage Guidelines
The signal label field occupies one byte of the path overhead associated with each SONET frame. It is
used to indicate the type of contents carried in the SPE. For example, 0x16 indicates scrambled
PPP/HDLC, while 0xCF indicates unscrambled PPP/HDLC. The default may be overridden by
specifying a particular
hex octet
that is to be used instead, where
hex octet
is a hexadecimal integer
in the range [0–xFF]. It may be necessary to specify a particular
hex octet
in order to interoperate with
implementations that do not follow the standard conventions for the signal label field.
Example
The following command example sets the Signal Label to the hexadecimal value
CF
for port 1 of the PoS
module installed in slot 8 of the BlackDiamond switch:
config sonet signal label CF ports 8:1
