Upgrading the Junos OS on the TX Matrix Plus Router and Line-Card Chassis

 

Before integration of a line-card chassis (LCC).

  • Integration of an offline LCC:

    • TXP-T1600 configuration—For offline integration of an LCC, you must upgrade the router to Junos OS Release 9.6R2 or later. Either 32-bit Junos or 64-bit Junos is supported. However, the SFC and LCC must run either 32-bit Junos or 64-bit Junos.

    • TXP-T1600-3D configuration, TXP-T1600-3D configuration, or TXP-Mixed-LCC-3D configuration—For offline integration of an LCC, you must upgrade the router to Junos OS Release 13.1 or later. 64-bit Junos OS is required.

  • Integration of an operational LCC:

    • The TX Matrix Plus router and LCCs must each contain two host subsystems. All host subsystems must be running the same Junos OS release. This is a requirement for graceful switchover. Graceful switchover must be enabled to integrate an operational LCC. For information about graceful switchover, see Configuring Graceful Switchover on the Line-Card Chassis and the Junos OS High Availability Library for Routing Devices.

    • TXP-T1600 configuration—For online integration of an LCC, you must upgrade the router to Junos OS Release 10.1 or later. Either 32-bit Junos or 64-bit Junos is supported. However, the SFC and LCC must run either 32-bit Junos or 64-bit Junos.

    • TXP-T1600-3D configuration, TXP-T1600-3D configuration, or TXP-Mixed-LCC-3D configuration—For integration of an operational LCC, you must upgrade the router to Junos OS Release 13.2 or later. 64-bit Junos OS is required.

To upgrade the software, you use CLI commands to copy a set of software images over the network to memory storage on the Routing Engine. The Junos OS set consists of several images provided in individual packages or as a bundle. You normally upgrade all packages simultaneously.

To upgrade the software:

  1. Upgrade the Junos OS running on the LCC.
  2. Upgrade the Junos OS on the TX Matrix Plus router to the same release running on the LCCs.
  3. After you are satisfied that the new packages are successfully installed and running, issue the request system snapshot all-chassis command to back up the new software.
