Commands for Security Function Chapter 6 Commands for TACACS+
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
will be reallocated.
Example:
Removing all IP-hardware address binding records.
Switch#clear ip dhcp binding all
Related Command:
show ip dhcp binding
15.1.3 clear ip dhcp conflict
Command:
clear ip dhcp conflict {<address> | all }
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.
Switch#clear ip dhcp conflict 10.1.128.160
