Chapter 12 Configuring LRE

Upgrading LRE Switch Firmware

Note You must remove global configurations that might affect the controller and devices connected to it.

Note If you enter the lre upgrade default family global configuration command and the upgrade binary

LRE binary [remote interface-id] controller configuration command, the upgrade binary controller

configuration command has precedence.

Performing an LRE Upgrade

You can upgrade either on a system-wide basis (in other words, upgrading the software on all connected

CPE devices and local LRE chipsets) or on individual CPE device or LRE controllers. By default, a

system-wide upgrade applies the most recent versions of LRE binaries that are most compatible with

each upgradable hardware module. The system-wide upgrade method is the one that you use in almost

all situations.

When executing upgrades, you can elect to upgrade a single CPE device or local controller by using the

hw-module slot module-slot-number upgrade lre [force] [local ctrlr-unit-number | remote interface-id]

privileged EXEC command. If no local or remote option is given, a system-wide upgrade is performed.

Beginning in privileged EXEC mode, follow these steps to perform a system-wide upgrade to configure

the LRE binary to apply to a target device and upgradable hardware element combination:

Note The lre upgrade default family global configuration command essentially overrides the system default

selection of an LRE binary for a specified family of CPE devices (target devices).

Beginning in privileged EXEC mode, follow these steps to explicitly direct the LRE binaries to be

applied to either the local controller or a specific very-high-data-rate digital subscriber line (V DSL) link:

Command Purpose

Step 1 configure terminal Enter global configuration mode.

Step 2 lre binary default target_device LRE_binary Enter the device to which the LRE binary should be applied and

the LRE binary to be applied.

Step 3 end Return to privileged EXEC mode.

Step 4 show lre upgrade version Verify the change.

Command Purpose

Step 1 configure terminal Enter global configuration mode.

Step 2 controller lre chipset_number Enter the particular LRE local chipset on the switch to be applied.
