Usage Guidelines
Use the hw-module slot command to start an LRE upgrade. You can start an LRE upgrade by using one
of these methods:
•
•
•
You can use the force keyword to upgrade an LRE binary on a local LRE controller or a remote LRE
CPE device, even though the device is already running the version of the desired LRE binary. The default
behavior is to not upgrade LRE binaries that are already up to date.
During an upgrade, users on the LRE links being upgraded experience a temporary disruption of
Ethernet connectivity. All LRE local and remote upgrades run concurrently and take 3 to 6 minutes to
complete.
The command-line interface (CLI) is available while an LRE upgrade is in progress.
