Release Information
Statement introduced in Junos OS Release 9.3 for EX Series switches.
Statement introduced in Junos OS Release 11.3 for the QFX Series.
Description
Configure the circuit-id suboption (suboption 1) of DHCP option 82 (the DHCP relay agent information option) in DHCP packets destined for a DHCP server. This suboption identifies the circuit (interface and/or VLAN) on which the DHCP request arrived.
The format of the circuit-id information for Gigabit Ethernet interfaces that use VLANs is interface-name:vlan-name . On a Layer 3 interface, the format is just interface-name.
The remaining statements are explained separately.
Default
If DCHP option 82 is enabled on the switch, the circuit ID is supplied by default in the format interface-name:vlan-name or, on a Layer 3 interface, just interface-name .
Required Privilege Level
system—To view this statement in the configuration.
system-control—To add this statement to the configuration.
