USG FLEX H Series supports DHCP Option 60 for VCI-based DHCP server selection. This helps route different client types, such as Internet or IPTV clients, to the appropriate DHCP server for service-specific configuration.
Set Up DHCP 60 on the USG FLEX H
1. Go to Network > Interface > External, and edit the WAN interface.
2. Make sure the WAN interface is set as a DHCP client. Select Get Automatically (DHCP) for Address Assignment.
3. Scroll down and expand the Advanced Settings: DHCP Option 60
4. Enter the VCI string in the field of DHCP Option 60, and click Apply
The VCI string is ISP-specific. Please enter the Vendor Class Identifier provided by your Internet Service Provider. There is no default universal VCI value for all connections.
Test DHCP Option 60 To check the functionality of DHCP Option 60, we can use packet capture software to check if option 60 string exists in the DHCP discover message that is sent from the USG FLEX H.
