DHCP Vendor Class Identifier Updates for Windows and Android Devices
MSFT 5.0 and DHCPCD-5.5.6
The DHCP vendor class identifier in DHCP requests has been updated for some Windows and Android devices. This change affects the way that DHCP servers identify and configure these devices.
Changes for Windows Devices
The traditional Client Vendor Name for Windows-based devices was MSFT 5.0. However, some devices will now show up as MSFT 5.0 with the new vendor class identifier.
Changes for Android Devices
The vendor class identifier for Android devices is now DHCPCD-5.5.6. This change affects all Android devices running Android 5.0 or later.
DHCP Option 43 Vendor-Specific Information
DHCP Option 43, Vendor-Specific Information, is a DHCP option that allows administrators to send vendor-specific information to DHCP clients. The value of DHCP Option 43 is only sent to clients that have a specific vendor class. For example, the value of DHCP Option 43 for MSFT 5.0 would only be sent to Windows-based devices.
Impact on DHCP Servers
DHCP servers must be configured to support the new vendor class identifiers. If a DHCP server is not configured to support the new vendor class identifiers, it will not be able to properly identify and configure Windows and Android devices.
Configuring DHCP Servers
Administrators can configure their DHCP servers to support the new vendor class identifiers by adding the following lines to the DHCP server configuration file:
``` option vendor-class-identifier "MSFT 5.0"; option vendor-class-identifier "DHCPCD-5.5.6"; ```Troubleshooting
If you are having trouble configuring your DHCP server to support the new vendor class identifiers, you can consult the following resources:
- Microsoft documentation on DHCP vendor class identifiers
- Android documentation on DHCP Option 43 support
