FPC Numbering for Interfaces in TXP-T1600-3D Configuration
A routing matrix with the TXP-T1600-3D configuration can include up to eight T1600 routers (also referred to as line-card chassis), which are assigned numbers from 0 through 7, depending on the chassis ID setting. In the Junos OS CLI, lcc 0 through lcc 7 are used to refer to T1600 routers in a routing matrix with the TXP-T1600-3D configuration. Each T1600 router can contain up to eight Flexible PIC Concentrators (FPCs) in FPC hardware slots labeled 0 through 7. Therefore, a routing matrix with a TX Matrix Plus router in the TXP-T1600-3D configuration can contain up to 64 FPCs. For information about which FPCs are supported in the TXP-T1600-3D configuration, see the TX Matrix Plus Router Hardware Guide .
In the Junos OS CLI, an interface name has the following format:
When you specify the FPC number for a T1600 router in a routing matrix, Junos OS determines which T1600 router contains the specified FPC. Table 1 shows the basic correspondence between FPC hardware slot numbers (0 through 7), which are labeled on the T1600 chassis, and the global FPC numbers (0 through 63), which are used in the Junos OS CLI.

T1600 Router | Basic Correspondence of FPC Numbering | |
|---|---|---|
FPC | Global | |
| LCC 0 | 0–7 | 0–7 |
| LCC 1 | 0–7 | 8–15 |
| LCC 2 | 0–7 | 16–23 |
| LCC 3 | 0–7 | 24–31 |
| LCC 4 | 0–7 | 32–39 |
| LCC5 | 0–7 | 40–47 |
| LCC 6 | 0–7 | 48–55 |
| LCC 7 | 0–7 | 56–63 |
To easily convert an FPC hardware slot number on a specific LCC (T1600 router) in a routing matrix to the corresponding global FPC number (routing matrix FPC number), use the conversion chart shown in Table 2. You can use the converted FPC number to configure the interfaces on the TX Matrix Plus router in your routing matrix.

You can use a CLI operational command to display the numbers of the connected FPCs in a routing matrix. To display the FPC numbers in global numbering mode (0 through 63, as used to specify an interface name in a routing matrix) and the associated local numbering mode (LCC number and FPC physical slot number), you can use various forms of the show chassis location command. For more information, see Displaying Chassis Physical Locations for a Routing Matrix with a TX Matrix Plus Router.
