B.1.1.1 Embedded Options - Using Option 43
This section provides instructions for automatic update of firmware and configuration file via DHCP
using extended options or standard options configured globally.
The setup example described in this section includes:
• 1 AP-5131
• 1 Microsoft Windows DHCP Server
• 1 TFTP Server
Note the following caveats regarding this procedure before beginning:
• Ensure the LAN Interface is configured as a DHCP Client
• If the existing and update firmware files are the same, the firmware will not get updated.
To configure the DHCP Server for automatic updates:
1. Set the Windows DHCP Server and AP-5131 on the same Ethernet segment.
2. Configure the Windows based DHCP Server as follows:
a. Highlight the Server Domain Name (for example, apfw.symbol.com). From the Action
menu, select Define Vendor Classes.
b. Create a new vendor class. For example, AP5131 Options.
c. Enter the Vendor Class Identifier SymbolAP.5131-V1-1. Enter the value in ASCII format,
the server converts it to hex automatically.
d. From the Action menu, select Set Predefined Options.
