Managing Switch Configuration and Files
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.
host Specifies the name or IP address of the remote host.
port (Optional) Specifies the server port number.
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.
