Release Information

Statement introduced in Junos OS Release 12.1 for EX Series switches.

Description

Configure extended DHCP relay options on the switch and enable the switch to function as a DHCP relay agent. A DHCP relay agent forwards DHCP request and reply packets between a DHCP client and a DHCP server.

The extended DHCP relay agent options configured with the dhcp-relay statement are incompatible with the DHCP/BOOTP relay agent options configured with the bootp statement. As a result, the extended DHCP relay agent and the DHCP/BOOTP relay agent cannot both be enabled on the switch at the same time. See DHCP/BOOTP Relay for Switches Overview for more information about the DHCP/BOOTP relay agent.

The remaining statements are explained separately.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
