Option: Configuring Chassis-Specific Statements for a Routing Matrix with a TX Matrix Router

You can configure PIC-specific features, such as SONET/SDH framing, on specific T640 routers within the routing matrix with a TX Matrix router. To do so, include the lcc lcc-number statement at the [edit chassis] hierarchy level and specify the chassis-specific feature to configure.

Note: When you include statements at the [edit chassis lcc lcc-number] hierarchy level, specify the actual FPC hardware slot number as labeled on the T640 router chassis. Do not use the routing matrix-based FPC number shown in T640 to Routing Matrix with a TX Matrix Router FPC Conversion Chart.

By default, the Junos OS allows all T640 routers in the routing matrix to come online. Optionally, you can configure the TX Matrix router to generate an alarm if the T640 routers in the routing matrix do not come online. To configure, include the online-expected statement at the [edit chassis lcc number] hierarchy level on the TX Matrix router.

If you do not want a T640 router to be part of the routing matrix, you can configure it to be offline. This is useful when you are performing maintenance on a T640 router. To configure a T640 router so that it is offline, include the offline statement at the [edit chassis lcc number] hierarchy level.

When you are ready to bring the T640 router back online, delete the offline configuration statement at the [edit chassis lcc number] hierarchy level.

Note: If you do not configure the online-expected or offline statement, any T640 router that is part of the routing matrix is allowed to come online. However, if a T640 router does not come online, the TX Matrix router does not generate an alarm.
