Command History
Usage Guidelines Use the show lre upgrade binaries command to display the LRE binary information for each interface.
The command output shows the path to the LRE binaries, which are always in the same directory as the
Cisco IOS image. LRE binary file names consist of:
• The device family. A device family could be an LRE switch or a customer premises equipment
(CPE) device.
• The function of the firmware, such as an upgrade for an application, the bootloader, or for the LRE
chipset.
• The firmware version.
Files marked with an exclamation point (!) are version description files. A version description file is only
for informational purposes and is not a candidate for upgrade. Version description files are used to
determine whether or not a CPE device on an LRE link is running a supported LRE binary version.
Use the show lre upgrade status command during LRE upgrades to display both the local and remote
upgrade status levels in progress on an LRE link. Status levels are:
• None—An upgrade is not in progress.
• Pending—An upgrade is initialized, but transfer has not begun.
• Active—Data transfer is in progress.
• Cmplt—An upgrade is complete.
binaries Display the LRE binaries present on the system flash memory.
status Display the upgrade status on all ports in the switch.
version Display the version of binaries on local and remote ends of an LRE link.
| begin (Optional) Display begins with the line that matches the specified expression.
| exclude (Optional) Display excludes lines that match the specified expression.
| include (Optional) Display includes lines that match the specified expression.
expression Expression in the output to use as a reference point.
