Global Configuration Of Lre Upgrades; Controller Configuration Of Lre Upgrades - Cisco 2950G 24 - Catalyst Switch Software Configuration Manual

Chapter 10 Configuring LRE

Global Configuration of LRE Upgrades

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:
Command
Step 1
configure terminal
Step 2 lre binary default target_device LRE_binary
Step 3 end
Step 4
show lre upgrade version
Note The lre upgrade default mode command essentially overrides the system default selection of an LRE
binary for a specified family of CPE devices (target devices).

Controller Configuration of LRE Upgrades

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 VDSL link:
Command
Step 1 configure terminal
Step 2
controller lre chipset_number
Step 3
upgrade <[remote lo x/y] LRE_Binary |
preserve>
Step 4
end
Step 5 show lre upgrade version
You can use the upgrade configuration command in the controller submode to override the system
default selection of an LRE binary that will be applied on either end of a particular LRE link. Controller
configurations take precedence over global upgrade configurations.
The preserve keyword causes the LRE upgrade mechanism to not upgrade the local controller on which
preserve is configured or any of the CPE devices connected to that controller. If you want to preserve
(in other words, not upgrade) some of the CPE devices connected to a particular controller but allow
upgrades to others, you can enter controller upgrade configuration commands for the links you want to
upgrade.
The no form of the command removes the command for applying a particular LRE binary. To resume
default upgrade behavior for a given controller, do not configure the custom upgrade commands on that
controller.

Purpose
Enter global configuration mode.
Enter the device to which the LRE binary should be applied; and
the LRE binary to be applied.
Return to privileged EXEC mode.
Verify the change.
Purpose
Enter global configuration mode.
Enter the particular LRE local chipset on the switch to be applied.
Enter the LRE binary to be applied, or set preserve, which
prevents the upgrade of any CPE devices connected to a
controller or local chipset.
Return to privileged EXEC mode.
Verify the change.
