To create a manual binding: Step 1 2 3 Task Command Syntax Create an address pool pool name Specify the client IP address. Specify the client hardware address or client-identifier. • hardware-address is the client MAC address. type is the protocol of the hardware platform. The default protocol is Ethernet. client-identifier is required for Microsoft clients instead of a hardware addresses. The client identifier is formed by concatenating the media type and the MAC address of the client. Refer to the "Address Resolution Protocol Parameters" section of RFC 1700-Assigned Numbers, for a list of media type codes. host address hardware-address hardware-address type client-identifier unique-identifier Command Mode DHCP DHCP DHCP Check for Address Conflicts By default, the DHCP server pings an address from the pool twice before assigning the address to a client to attempt to verify that it is not in use. If the ping is unanswered, the DHCP server assumes that the address is not in use and assigns the address. By default, the DHCP server waits 500 milliseconds before timing out a ping packet. Task Specify the number of ping packets the DHCP server sends to the pool address before assigning the address. Change the amount of time the server waits for a ping reply before considering the ping a failure. Command Syntax Command Mode ip dhcp ping packets number Default: 2 CONFIGURATION ip dhcp ping timeout milliseconds CONFIGURATION Default: 500 milliseconds An address conflict occurs when two hosts use the same IP address. The server checks for a conflict using ping and the client checks for conflict using gratuitous ARP. If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict. Task Log IP address conflicts.
