 Function: Deletes an address present in the address conflict log.

 Parameters: <address> is the IP address that has a conflict record; all stands for all

addresses that have conflict records.

 Command mode: Admin Mode.

 Usage Guide: “show ip dhcp conflict” command can be used to check which IP

addresses are conflicting for use. The “clear ip dhcp conflict” command can be used to

delete the conflict record for an address. If "all” is specified, then all conflict records in

the log will be removed. When records are removed from the log, the addresses are

available for allocation by the DHCP server.

 Example: The network administrator finds 10.1.128.160 that has a conflict record in the

log and is no longer used by anyone, so he deletes the record from the address conflict

log.
