ip dhcp-relay source-interface

Configures the DHCP relay source interface to be used by the DHCP relay agents to forward the packets to and from the DHCP server.

Syntax
ip dhcp-relay {source-interface [ethernet node/slot/port | loopback loopback-id | port-channel id-number | vlan vlan-id | virtual-network vn-id]
Parameters
  • ethernet node/slot/port—Enter the Ethernet interface type.
  • loopback loopback-id—Enter the Loopback interface type.
  • port-channel id-number—Enter the port channel ID, from 1 to 999 or 1001 to 2000.
  • vlan vlan-id—Enter the VLAN interface type.
  • virtual-network vn-id—Enter the virtual network type.
Defaults
No source-interface configuration on the interface and the client connected interface IP address is used by the relay for forwarding.
Command Mode
INTERFACE CONFIGURATION
Usage Information

When you configure the DHCP-relay source interface on a given DHCP client facing interface, the DHCP server uses the IP address of that source interface as the destination for the RELAY-REPLY packets.

This interface level source-interface configuration takes precedence over the VRF source-interface configuration, if configured. The source-interface IP address takes precedence for the giaddr field even if an interface IP address or virtual anycast gateway IP address is present on the interface.

You can configure the source-interface on all types of DHCP client interfaces (Ethernet interface, port channel, VLAN, and virtual-network).

NOTE: You must enable the link-selection option globally to allocate the IP address on the client subnet if the client-connected interface IP address and source interface IP address are in different network domains.

This command is restricted to netadmin and sysadmin role users.
