range. This field is not required when specifying a single IP address.

Applicable Platforms
This command applies to the NetVanta 300, 1000, 1000R, 2000, 3000, 4000, and 5000 and
Total Access 900 Series units.
Command History
Release 2.1 Command was introduced.
Functional Notes
The AOS DHCP server (by default) allows all IP addresses for the DHCP pool to be assigned to requesting
clients. This command is used to ensure that the specified address is never assigned by the DHCP server.
When static addressed hosts are present in the network, it is helpful to exclude the IP addresses of the
host from the DHCP IP address pool. This will avoid IP address overlap.
Usage Examples
The following example excludes an IP address of 172.22.5.100 and the range 172.22.5.200 through
172.22.5.250:
(config)#ip dhcp-server excluded-address 172.22.5.100
(config)#ip dhcp-server excluded-address 172.22.5.200 172.22.5.250
