Configuring Performance Rate of Line Modules on ERX-7xx Models and the ERX-1410 Router

Note: The information in this section does not apply to the ERX-1440 router, ERX-310 router, E120 router, or the E320 router. It also does not apply to the OC48 line module, which is supported only by the ERX-1440 router.

Line modules in an ERX-1440 router or an ERX-310 router always operate at line rate performance. However, you can configure ERX-7xx models and the ERX-1410 router to enable the line modules either to operate at full line rate performance or to allow line modules to operate at a rate dependent on the resources available.

Operating at full line rate performance restricts the combination of line modules in the router. Operating at a rate dependent on the resources available allows a much more extensive combination of line modules in the router and is known as bandwidth oversubscription.

To configure performance:

Choose a combination of line modules appropriate for the performance. See Choosing a Combination of Line Modules.
Disable slots that contain unwanted line modules, or modify the combination of line modules in the router. See Disabling and Reenabling Line Modules, SRP Modules, and SFMs, and ERX Hardware Guide, Chapter 4, Installing Modules.
Specify the type of performance. See Specifying the Type of Performance.
