AV Line of Fully Managed Switches M4250 Series Main User Manual • Disabled: The auto install process does not save the downloaded configuration file and, therefore, cannot apply it after the switch reboots. h. From the AutoSave Mode menu, select to enable or disable automatic saving of the configuration to the startup configuration: • Enabled: The automatically downloaded configuration is saved to the startup configuration. • Disabled: The automatically downloaded configuration is not saved to the startup configuration. If you want to save the configuration you must do to manually. This is the default setting. i. In the AutoInstall Retry Count menu, specify the number of times that the switch sends a unicast message to the TFTP server. The TFTP server is specified in the DHCP configuration (see Option 125 DHCP server requirements for obtaining an configuration file through auto install on page 736). After the specified number of times is exceeded, the switch sends broadcast messages to the TFTP server. The range is from 1 to 3. By default, the number is 3. j. Click the Apply button. Your settings are saved. The Auto-Install State field displays the status of the auto install process. Option 125 DHCP server requirements for obtaining an configuration file through auto install You can use auto install to let the switch download a configuration file (image file) from a TFTP server using DHCP option 125. The image update can either upgrade or downgrade the firmware on the switch. For the switch to be able to download an image from a TFTP server, the DHCP server must include an image description file that lists the image that the switch must download from the TFTP server. For example, the autoinstall_dhcp image description file on the DHCP server lists the M4XXX-v1.2.3.4.stk image that the switch must download from the TFTP server. Option 125 in the DHCP server must contain the following information (the example uses the autoinstall_dhcp image description file and the M4XXX-v1.2.3.4.stk image): • Enterprise number (4 octets). 0x0000 0x11ae In decimals, the enterprise number for NETGEAR is 4526.
