DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Multiple relay target commands can be specified for a class. If a packet matches the class, the packet will be forwarded to all of the relay targets. If the relay target command is not configured for a class, the relay target follows the relay destination specified for the pool. The DHCP packet will not be relayed, if the interface that receives the packet has no IP address configured. Example This example shows how to configure a DHCP relay target for relaying packets that matches the value pattern of the option defined in the class.
