Using the JUNOS Software to Configure a T640 Router Within a Routing Matrix

A routing matrix composed of a TX Matrix router and T640 routers supports the same chassis configuration statements as a standalone router (except ce1, ct3, mlfr-uni-nni-bundles, sparse-dlcis, and vtmapping). By including the lcc statement at the [edit chassis] hierarchy level, you configure PIC-specific features, such as framing, on specific T640 routers. In addition, a routing matrix has two more chassis configuration statements, online-expected and offline.

To configure a T640 router that is connected to a TX Matrix router, include the lcc statement at the [edit chassis] hierarchy level:

[edit chassis]lcc number;

number can be 0 through 3.

To configure a T640 router within a routing matrix, include the following statements at the [edit chassis lcc number] hierarchy level:

[edit chassis lcc number]fpc slot-number { # Use the hardware FPC slot numberpic pic-number {atm-cell-relay-accumulation;atm-l2circuit-mode (cell | aal5 | trunk trunk);framing (sdh | sonet);idle-cell-format {itu-t;payload-pattern payload-pattern-byte;}max-queues-per-interface (8 | 4);no-concatenate;}offline;online-expected;q-pic-large-buffer {large-scale;}

Note: For the FPC slot number, specify the actual hardware slot number (numbered 0 through 7) as labeled on the T640 router chassis. Do not use the corresponding software FPC number shown in TX Matrix Router Chassis and Interface Names.

For information about how to configure the online-expected and offline configuration statements, see Configuring the JUNOS Software to Enable the TX Matrix Router to Generate an Alarm If a T640 Router Stays Offline.
