Loading and saving configuration files

Setting up consoles

Hitless Layer 2 OS upgrade is executed at the active management module. During the process of

upgrading the image, control of the router shifts to the standby management module. For this

reason, you need to have management sessions enabled on both the active and the standby

management modules. When the reload is complete, the management module that was in the

standby condition at the beginning will be in the active state. If you want the original management

module to be active, you must manually fail-over control to it.

Executing the hitless upgrade command

To begin the process of a hitless upgrade, use the following command:

BigIron RX(config)# hitless-reload mp primary lp primary

Syntax: hitless-reload mp [primary | secondary ] lp [primary | secondary]

The mp parameter specifies that the management module will be reloaded with either the primary

or secondary image as directed.

The lp parameter specifies that the interface module will be reloaded with either the primary or

secondary image as directed.

Verify the new software image

Enter the show version command at any CLI level, and verify that all management and interface

modules are running the new software image version.

Loading and saving configuration files

For easy configuration management, the BigIron RX Series switch supports both the download and

upload of configuration files between the switch and a TFTP server on the network. You can also

copy the startup configuration file locally between the management module’s code flash and a

PCMCIA flash card inserted in the management module’s slot 1 or 2.

You can upload either the startup configuration file or the running configuration to the TFTP server,

code flash, or a flash card for backup and use in booting the system.

• Startup configuration file – This file (startup-config) contains the configuration information

that is currently saved in the management module’s code flash. To display this file, enter the

show configuration command at any CLI prompt.

• Running configuration – This active configuration is in the system RAM but not yet saved to

code flash. These changes could represent a short-term requirement or general configuration

change. To display this configuration, enter the show running-config or write terminal

command at any CLI prompt.

Each device can have one startup configuration file and one running configuration. The startup

configuration file is shared by both flash modules. The running configuration resides in DRAM.
