Configuration Persistence Mode

The default state of configuration persistence mode is “auto,” which means that when CLI configuration commands are entered, or when a configuration file stored on the switch is executed, the configuration is saved to NVRAM automatically at the following intervals:

•On a standalone unit, the configuration is checked every two minutes and saved if there has been a change.

•On a stack, the configuration is saved across the stack every 30 minutes if there has been a change.

If you want to save a running configuration to NVRAM more often than the automatic intervals, execute the save config command and wait for the system prompt to return. After the prompt returns, the configuration will be persistent.

You can change the persistence mode from “auto” to “manual” with the set snmp persistmode command. If the persistence mode is set to “manual,” configuration commands will not be automatically written to NVRAM. Although the configuration commands will actively modify the running configuration, they will not persist across a reset unless the save config command has been executed.

Note: When your device is configured for manual SNMP persistence mode, and you attempt to change the boot system image, the device will not prompt you to save changes or warn you that changes will be lost.

Purpose

To set and view the persistence mode for CLI configuration commands, manually save the running configuration, view, manage, and execute configuration files and image files, and set and view TFTP parameters.
