You can also configure the extended DHCP local server to match the DHCP relay agent information option (option 82) in the client DHCP packets to a named range in the address-assignment pool used for the client. Named ranges are subsets within the overall address-assignment pool address range, and are configured when you create the address-assignment pool. To use the DHCP local server option 82 matching feature, you must ensure that the option-82 statement is included in the dhcp-attributes statement for the address-assignment pool.

Note: To enable the option 82 matching method, you must first specify the ip-address-first statement in the pool-match-order statement, and then specify the option-82 statement. |
