Set the DSCP value for DHCPpackets sent by the DHCPclient.dhcp dscp dscp-value By default, the DSCP value in DHCP packetssent by the DHCP client is 56.Displaying and maintaining the DHCP clientExecute display command in any view.Task CommandDisplay DHCP client information. display dhcp client [ verbose ] [ interface interface-typeinterface-number ]DHCP client configuration exampleNetwork requirementsAs shown in Figure 24, Router B contacts the DHCP server through Ethernet 1/1 to obtain an IP address,DNS server address, and static route information. The DHCP client IP address resides on network10.1.1.0/24. The DNS server address is 20.1.1.1. The next hop of the static route to network 20.1.1.0/24is 10.1.1.2.The DHCP server uses Option 121 to assign static route information to DHCP clients. Figure 23 shows theOption 121 format. The destination descriptor field contains the following parts: subnet mask length anddestination network address, both in hexadecimal notation. In this example, the destination descriptor is18 14 01 01 (the subnet mask length is 24 and the network address is 20.1.1.0 in dotted decimalnotation). The next hop address is 0A 01 01 02 (10.1.1.2 in dotted decimal notation).Figure 23 Option 121 formatFigure 24 Network diagram
