Release Information Statement introduced in Junos OS Release 9.0.
Statement introduced in Junos OS Release 12.3R2 for EX Series switches.
Description Configure the extended DHCP local server to use the option 82 value in the DHCP client
DHCP PDU together with the ip-address-first method to determine which
address-assignment pool to use. You must configure the ip-address-first statement
before configuring the option-82 statement. The DHCP local server first determines which
address-assignment pool to use based on the ip-address-first method. Then, the local
server matches the option 82 value in the client PDU with the option 82 configuration in
the address-assignment pool. This statement is supported for IPv4 address-assignment
pools only.
