Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide The DHCP server uses the ping session to detect the address conflict, while the DHCP client uses the address resolution protocol (ARP) to detect the address conflict. The clear ip dhcp conflict command can be used to delete the history conflict record. Note the following behavior for the clear ip dhcp conflict command: • If you do not specify the VRF name option and an IP address is specified, it is assumed that the IP address is an address in the global address space and will look among all the nonvirtual VRF DHCP pools for the specified conflict. • If you do not specify the VRF name option and the * option is specified, it is assumed that all automatic or on-demand conflicts in all VRF and non-VRF pools are to be deleted. • If you specify both the VRF name option and the * option, all automatic or ondemand conflicts in the specified pool only will be cleared. • If you specify the VRF name option and an IP address, the specified conflict will be deleted from the specified pool. Example This example shows how to clear all address conflict records. DXS-3600-32S#clear ip dhcp conflict * DXS-3600-32S# 14-4 default-router This command is used to define the default gateway of the DHCP client in the DHPC address pool configuration mode. The no form of this command can be used to delete the definition of the default gateway. default-router ip-address [ip-address2 [ip-address3]] no default-router Parameters ip-address ip-address2 ip-address3 Specifies to define the IP address of the equipment. It is required to configure one IP address at least. (Optional) Up to 3 gateways can be configured. Default Command Mode Command Default Level Usage Guideline No gateway is defined by default. DHCP Address Pool Configuration Mode. Level: 8 In general, the DHCP client should get the information of the default gateway from the DHCP server. The DHCP server should specify one gateway address for the client at least, and this address should be of the same network segment as the address assigned to the client. Example This example shows how to define 192.168.12.1 as the default gateway. DXS-3600-32S#configure terminal DXS-3600-32S(config)#ip dhcp pool pool1 DXS-3600-32S(dhcp-config)#default-router 192.168.12.1 DXS-3600-32S(dhcp-config)# 14-5 dns-server This command is used to define the DNS server of the DHCP client in the DHPC address pool configuration mode. The no form of this command can be used to delete the definition of the DNS server. dns-server ip-address [ip-address2 [ip-address3]] 207
