SG1-UM-8500-03 7-15
Usage
port sonet <slot> \ <port> type (OC3c|STM1)
Parameter(s)
<slot>
The line card slot to be configured. Use the value 2 to indicate the configuration of the SONET/SDH port.
<port>
The line card port to be configured (either 1 or 2).
(OC3c|STM)
The type of physical interface:
•OC3c–the North American standard for 155.52 Mbps data over optical fiber.
•STM–the standard for 155.52 Mbps data over optical fiber outside of North America.
Example(s)
Configuring SONET/SDH port redundancy
SG1 systems use APS to switch ATM traffic from the main SONET/SDH channel (the working channel) to a
secondary SONET/SDH channel (the protection channel on the same card) when a failure occurs. This redundancy
enables service to continue despite failures on the working SONET/SDH channel. Refer to the System Technology
and Applications Overview for an explanation of how an APS works.
Usage
port sonet redundancy-enable <working slot> \ <working port> \ <protect slot> \
<protect port> [SFBER <number>] [SDBER <number>]]
Parameter(s)
<working slot>
The slot number to be designated as the working slot (valid value = 2).
<working port>
The port number to be designated as the working port (valid value = 1 or 2).
<protect slot>
The slot number to be designated as the protect slot (valid value = 2).
