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 Altitude 3510 or Altitude 3550 model access point
● 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 access point on the same Ethernet segment.
2 Configure the Windows based DHCP Server as follows:
a Highlight the Server Domain Name (for example, apfw.extremenetworks.com). From the Action
menu, select Define Vendor Classes.
b Create a new vendor class. For example, AP35xx Options.
c Enter the vendor class Identifier ExtremeAP.35xx-V1-1-1. Enter the value in ASCII format, the
server converts it to hex automatically.
d From the Action menu, select Set Predefined Options.
e Add the following 3 new options under AP35xx Options class:
f Highlight Scope Options from the tree and select Configure Options.
g Go to the Advanced tab. From under the Vendor Class AP35xx Options, check all three options
mentioned in the table above and enter a value for each option.
3 Copy the firmware and configuration files to the appropriate directory on the TFTP Server.
