Configuring SONET Framing

You can configure each port for framing that complies with either the SONET standard
or the SDH standard. SONET is primarily an American standard; SDH is the
international version. The default is SONET.
To configure the framing for the specified SONET feature on an ATM port, use the
following command:
config sonet framing [sonet | sdh] ports <portlist>
The following command example selects SDH framing for port 1 of the ATM module
installed in slot 8 of the BlackDiamond switch.
config sonet framing sdh ports 8:1

Configuring SONET Clocking

You can configure each port on the ATM module to use either line clocking, where the
clock source is recovered from the received bit stream, or internal clocking, where the
clock source is based on an internal clock. The default is internal.
To configure the clocking source for the specified ATM port, use the following
command:
config sonet clocking [line | internal] ports <portlist>
The following command example selects line clocking for port 1 of the ATM module
installed in slot 8 of the BlackDiamond switch.
config sonet clocking line ports 8:1
