DCS-3950 series Ethernet switch manual
Parameters: <address> is the IP address that has a binding record in decimal format. all
refers to all IP addresses that have a binding record.
Command mode: Admin Mode
Usage Guide: ‘show ip dhcp binding’ command can be used to view binding
information for IP addresses and corresponding DHCP client hardware addresses. If the
DHCP server is informed that a DHCP client is not using the assigned IP address for some
reason before the lease period expires, the DHCP server would not remove the binding
information automatically. The system administrator can use this command to delete that
IP address-client hardware address binding manually, if ‘all’ is specified, then all auto
binding records will be deleted, thus all addresses in the DHCP address pool wil be
reallocated.
Example: Remove all IP-hardware address binding records.
Switch#clear ip dhcp binding all
Relative Command：show ip dhcp binding
18.3.1.2 clear ip dhcp conflict
Command：clear ip dhcp conflict {<address> | all }
Function: Delete 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.
Switch#clear ip dhcp conflict 10.1.128.160
