Partitioning Overview

Router processor modules use three types of memory:

• Global

• Local

• Nonvolatile RAM (NVRAM)

Global and local memory are separate partitions of a single, contiguous memory

address space. The RAM chips associated with this address space exist physically

on each processor module.

The NVRAM for each processor module stores the memory partitioning

configuration associated with that module. You cannot partition NVRAM.

You can specify the amount of local and global memory (that is, the size of the

local and global memory partitions) used by a given processor module. Increasing

the size of the global memory partition automatically decreases the size of the

local memory partition. The router software ensures that the sum of local and

global memory always equals the total amount of memory available on a given

processor module.

Repartitioning Global and Local Memory

To repartition global and local memory:

1. Connect to the router.

See Chapter 1, “Getting Started with Site Manager,” for instructions.

Note:

NVRAM is present on each FRE-2 processor module inside the router.

If you move a FRE-2 module to another slot in the router, the memory

partitioning configuration moves with the FRE-2 module to the new slot.

Caution:

Change memory partitioning only at the recommendation of, or

under the direction of, the Nortel Networks Technical Solutions Center. Under

normal router and network operating conditions, there is no need to modify the

default memory partitions established for a processor module. You reallocate

processor memory partitions in rare instances, and only for the purpose of

network troubleshooting.
