Chapter 19 Upgrading Avaya M770 ATM Switch Software

Activating a configuration file
You can restore an old configuration file stored in the flash directory that was
generated with the system snapshot command.
To activate a configuration file, use the flash config command.
Note: The restored configuration file will only be activated when the switch is next
rebooted.
Note: After activating a new configuration file and performing a reset to the
module, the module takes longer than usual to boot because it is using the new
values. Because of this, when activating a configuration file that has switch-wide
parameters (such as the ATM prefix or IP address) different from the current RAM
settings, the module needs to be alone in the switch. If there are other modules in
the switch, the module using the new config file will take longer to boot up, and
another module in the switch will become the Master Agent and use the old switch-
wide settings.
When the module reboots using the new configuration file, the current LANE
configuration is saved in the file config.bak. If you need to restore the previous
LANE configuration, you need to perform the following steps.
1. Delete the file config.data using the flash delete command.
2. Rename the file config.bak to config.data using the flash rename command.
3. Reset the module using the <- -> reset pushbuttons on the module front panel.
Deactivating an active configuration file
To deactivate an active configuration file, use the flash config
disable command.
Command: M15-155s8:/>flash config <filename>
Example M15-155s8:/>flash config new_cfile
Parameters: <filename> The name of the configuration file that you wish to
activate
Command: M15-155s8:/>flash config disable
Output: No configuration file is currently active.
