Creating Manual Binding Entries
An address binding is a mapping between the IP address and the media access control (MAC) address of a client.
The DHCP server assigns the client an available IP address automatically, and then creates an entry in the binding table.
However, the administrator can manually create an entry for a client; manual bindings are useful when you want to guarantee
that a particular network device receives a particular IP address. Manual bindings can be considered single-host address pools.
There is no limit on the number of manual bindings, but you can only configure one manual binding per host.
NOTE: The Dell Networking OS does not prevent you from using a network IP as a host IP; be sure to not use a network IP
as a host IP.
1. Create an address pool.
DHCP mode
pool name
2. Specify the client IP address.
DHCP <POOL> mode
host address
3. Specify the client hardware address.
DHCP <POOL> mode
hardware-address hardware-address type
●
hardware-address: the client MAC address.
● type: the protocol of the hardware platform.
The default protocol is Ethernet.
Debugging the DHCP Server
To debug the DHCP server, use the following command.
● Display debug information for DHCP server.
EXEC Privilege mode
debug ip dhcp server [events | packets]
Using DHCP Clear Commands
To clear DHCP binding entries, address conflicts, and server counters, use the following commands.
● Clear DHCP binding entries for the entire binding table.
EXEC Privilege mode
clear ip dhcp binding
●
Clear a DHCP binding entry for an individual IP address.
EXEC Privilege mode
clear ip dhcp binding ip address
● Clear a DHCP address conflict.
EXEC Privilege mode
