Use the no form of this command to remove the association. class NAME no class NAME Parameters NAME Specifies the DHCP class name. This name can be up to 32 characters long. Default None. Command Mode DHCP Pool Configuration Mode. Command Default Level Level: 12 Usage Guideline This command is used to associate a DHCP relay pool with a DHCP pool class. Use the relay target command to define the list of relay target addresses for DHCP packet forwarding. If the DHCP client request matches a relay pool, which is configured with classes, the client must match a class configured in the pool in order to be relayed. If no DHCP class is configured, the request will only be matched against the relay pool and will be relayed to the relay destination server specified for the matched relay pool. Example This example shows how to configure a DHCP class, "Service-A", defined with DHCP Option 60 matching pattern 0x112233 and 0x102030, classified to the relay pool, "pool1", and is associated with relay target "10.2.1.2".
