DHCP Address Allocation with Option 82
The DHCP server provided by the V8102 can assign dynamic IP addresses based on
DHCP option 82 information sent by the DHCP relay agent.
The information sent via DHCP option 82 will be used to identify which port the
DHCP_REQUEST came in on. The feature introduces a new DHCP class capability,
which is a method to group DHCP clients based on some shared characteristics other
than the subnet in which the clients reside. The DHCP class can be configured with op-
tion 82 information and a range of IP addresses.
