Using Global FPC Numbering for Interfaces in a Routing Matrix with a TX Matrix Plus Router
When configuring interfaces on a routing matrix with a TX Matrix Plus router, you must adjust the routing matrix configuration to accommodate increased FPC numbers used in interface names.
For example, if you have a Gigabit Ethernet interface installed in FPC slot 7, PIC slot 0, port 0 of T1600 router lcc 3, you can configure this interface on the TX Matrix Plus router by including the ge-31/0/0 statement at the [edit interfaces] hierarchy level:
For more information about converting FPC hardware slot numbers on a T1600 router to the global FPC numbers used for interfaces in a routing matrix and vice versa, see Global FPC Numbering for Interfaces in a Routing Matrix with a TX Matrix Plus Router and Displaying Chassis Physical Locations for a Routing Matrix with a TX Matrix Plus Router.
 | Note: When you include the fpc statement at the [edit chassis lcc lcc-number] hierarchy level, specify the FPC hardware slot number (0 through 7) as labeled on the T1600 router chassis. Do not specify the corresponding global FPC number (0 through 31). |
