Network segment that does not include a server, UDP broadcasts normally are notīecause it does not forward broadcast traffic. Information about the network to which they are attached. DHCP clients use UDPīroadcasts to send their initial DHCPDISCOVER messages because they do not have Received on an interface to one or more DHCP servers. You can configure a DHCP relay agent to forward DHCP requests Only accepts IR packets, and does not assign addresses to the clients. You can configure the ASA to provide information such as the DNS server orĭomain name when they send Information Request (IR) packets to the ASA. Superseded by the manually defined domain name.įor clients that use StateLess Address Auto Configuration (SLAAC) inĬonjunction with the Prefix Delegation feature ( Enable the IPv6 Prefix Delegation Client), The domain name discovered by the DHCP automatic configuration process is Passed to DHCP clients with the discovered DNS and WINS server names, because Together with the DNS and WINS servers, the manually defined domain name is Although DHCP automatic configuration discovers the domain Name that you want the DHCP clients to receive and then enable DHCP automaticĬonfiguration. Method to define this information, it is passed to DHCP clients in theįor example, you can manually define the domain To obtain these values or define them manually. The DNS domain suffix.You can also use the DHCP automatic configuration setting WINS, and domain name parameters to DHCP clients DHCP option 15 is used for You can use advanced DHCP options to provide DNS, The response if they are already configured on the ASA. In this case, the ASA DHCP server provides values for both options in Gives the IP address or the hostname of a single TFTP server.Ī single request might include both options 150Īnd 66. Provides the IP addresses of a list of TFTP servers. Preconfigured, it sends a request with option 150 or 66 to the DHCP server to Starts, if it does not have both the IP address and TFTP server IP address
