Statement introduced in Junos OS Release 11.3 for the QFX Series.
Hierarchy level [edit vlans vlan-name forwarding-options dhcp-security option-82] introduced in Junos OS Release 13.2X50-D10. (See Using the Enhanced Layer 2 Software CLI for information about ELS.)
Insert the remote-id suboption of DHCP option 82 (also known as the DHCP relay agent information option) in DHCP request packet headers before forwarding or relaying requests to a DHCP server. This suboption provides a trusted identifier for the host system that has forwarded or relayed requests to the server.
The remaining statements are explained separately, and their availability depends on the hierarchy level at which the remote-id suboption is specified, as follows:
The statement prefix, is not supported at the [edit vlans vlan-name forwarding-options dhcp-security option-82] hierarchy level.
The statement host-name is supported only at the [edit vlans vlan-name forwarding-options dhcp-security option-82] hierarchy level.
If the remote-id statement is not explicitly set, no remote ID value is inserted in the DHCP request packet header.
If the remote-id statement is explicitly set, but is not qualified by a keyword, the following are true:
At the [edit vlans vlan-name forwarding-options dhcp-security] hierarchy level, the default keyword value is interface-name.
At all other hierarchy levels, the default value of the remote-id keyword is the MAC address of the switch.
When you configure remote-id, circuit-id is also enabled, even if you do not explicitly configure circuit-id.
