hw-module slot
Use the hw-module slot privileged EXEC command to perform firmware upgrades on Long-Reach
Ethernet (LRE) systems.

This command is available only on Catalyst 2950 LRE switches.
Syntax Description
Defaults No default is defined.
Command Modes Privileged EXEC
Command History
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:
• Upgrade all LRE local chipsets (controllers) and remote CPE devices by entering the hw-module
slot module-slot-number upgrade lre command.
• Upgrade a single local LRE controller by entering the hw-module slot module-slot-number lre
upgrade local ctrlr-unit-number command.
• Upgrade a single remote LRE CPE device by entering the hw-module slot module-slot number lre
upgrade remote interface-id command.
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.
module-slot-number Physical slot that connects the local device (LRE switch) and the remote
customer premises equipment (CPE) device for the upgrade.
force (Optional) LRE binaries update by force, even when the version of the LRE
binary on the switch flash memory and the LRE binary in use are the same.
local ctrlr-unit-number (Optional) The single LRE chipset for a controller at the local end of the
LRE Ethernet link.
remote interface-id (Optional) One or more chipsets on a single CPE device at the remote end
of the LRE Ethernet link.
