DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch CLI Reference Guide Example This example shows how a DHCP relay pool "pool2" is created. In the relay pool, the subnet 172.19.18.0.0/255.255.255.0 is specified as the source subnet and 10.2.1.10 is specified as the relay destination address. Switch# configure terminal Switch(config)# ip dhcp pool pool2 Switch(config-dhcp-pool)# relay source 172.19.18.0 255.255.255.0 Switch(config-dhcp-pool)# relay destination 10.2.1.10 Switch(config-dhcp-pool)# 21-17 relay target This command is used to specify a DHCP relay target for relaying packets that matches the value pattern of the option defined in the class. Use the no form of this command to delete a relay target. relay target IP-ADDRESS no relay target IP-ADDRESS Parameters IP-ADDRESS Specifies the relay target server IP address for the class. Default None. Command Mode DHCP Pool Class Configuration Mode. Command Default Level Level: 12. Usage Guideline In a DHCP relay pool, administrators can further use the class command and the relay target command to associate a list of relay target addresses with a DHCP class. When the client request matches a relay pool and the DHCP relay pool is defined with classes, the client request must match a class specified in the pool in order to be relayed. If the packet does not match any class in the pool, the packet will not be replayed. If the matched relay pool has no class defined, then the request will be relayed to the relay destination of the matched relay pool. 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. 255
