Chapter 7: Second Level Commands

Usage

port sonet <slot> \ <port> type (OC3cSTM1)

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).

(OC3cSTM)

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)

Host(config)# port sonet 2 \ 1 type OC3C

Updated item

Host(config)#

Configuring SONET/SDH port redundancy

Host(config)# port sonet redundancy-enable

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).
