the default setting.
lre upgrade default family device-family {model model {revision revision | binary LRE binary} |
binary LRE binary}
no lre upgrade default family device-family {model model {revision revision | binary LRE
binary} | binary LRE binary}
This command is available only on Catalyst 2950 LRE switches.
Syntax Description

Command Modes Global configuration
Command History
Usage Guidelines Use the lre upgrade default family device-family binary configuration command to override the default
behavior for upgrading LRE firmware. Use this command when you want to upgrade all CPE devices or
local controllers of a given family to an LRE binary version.
Note The name of the LRE binary must be entered as it appears in the flash memory. Use the show lre
upgrade binaries command to determine the flash filename of an LRE binary.
Examples This example shows how to configure all CISCO585-LRE CPE devices to upgrade with the LRE binary
file CISCO-585-LRE_vdslsngl_51.00.00:
Switch(config)# lre upgrade default family cisco585-lre binary
cisco585-lre_vdslsngl_51.00.00.bin
device-family Type of device that contains the chipset to be upgraded. Valid values are
cisco575-lre, cisco585-lre, cisco576-lre997, and cisco2950-lre.
model model Specify the model number of the device family; for example, a model can be
cisco585-lre.
revision revision (Optional) Specify the revision of the target device.
