upgrade binary
Use the upgrade binary controller configuration command to configure the behavior of a Long-Reach
Ethernet (LRE) controller upgrade.
upgrade binary LRE binary [remote lre-interface]
no upgrade binary LRE binary [remote lre-interface]
This command is available only on a Catalyst 2950 LRE switch.
Syntax Description
Command Modes Controller configuration
Command History
Usage Guidelines Use this command only when you need to specify a particular upgrade binary file for a local controller
in an LRE switch or for a remote CPE device connected to the controller. The default behavior for an
upgrade is for the system to select the binary version. If you use the upgrade binary LRE binary
command without parameters, the LRE binary is applied to the local controller when it is upgraded. If
you specify the remote keyword and interface, the LRE binary is applied to the CPE device at the end
of the remote LRE link at upgrade time.
Upgrade configurations given in the controller configuration mode take precedence over upgrade
configurations given in the global configuration mode.
Examples This example shows how to configures a Cisco 585 LRE CPE on an LRE link to use version 51.00.00.bin
the next time LRE update runs:
Switch# configure terminal
Switch(config)# controller longreachethernet 0
Switch(config-controller)# upgrade binary cisco585-lre_vdslsngl_51.00.00.bin remote
longreachethernet 0/1
Related Commands
LRE binary The LRE binary file name being applied.
remote lre-interface (Optional) The LRE interface. If you do not specify the remote parameter
for the customer premises equipment (CPE) end of the LRE link, the local or
controller end of the LRE link is implied.
