Configuring The Signal Label - Extreme Networks BlackDiamond 6800 Installation And User Manual

To configure the Path Trace identifier for the specified ATM port, use the following
command:
config sonet trace path <id_string> ports <portlist>
The
id_string
When SONET framing is configured, a 62-character string is transmitted repetitively,
one character per frame. If the configured string consists of fewer than 62 characters, it
is padded to its full length with NULL characters.
When SDH framing is configured, the maximum length of the
15 characters. If the configured string consists of more than 15 characters, it is truncated
to 15 characters.
The following command example sets the Path Trace identifier to the string "parador"
for port 1 of the ATM module installed in slot 8 of the BlackDiamond switch.
config sonet trace path parador ports 8:1

Configuring the Signal Label

The Signal Label field occupies one byte (C2) of the Path Overhead associated with each
SONET frame. It is used to indicate the type of contents carried in the Synchronous
Payload Envelope (SPE). For example, 0x13 indicates that the SONET SPE contains
ATM cells.
To configure the C2 Signal Label value for the specified ATM port, use the following
command:
config sonet signal label [auto | <hex_octet>] ports <portlist>
The
hex_octet
FF. It may be necessary to specify a particular Signal Label value in order to
interoperate with implementations that do not follow the standard conventions for the
Signal Label field.
To determine whether you need to specify a particular Signal Label value, perform the
following tasks:
