Parameters
start-ip-address: Specifies the start IP address.
end-ip-address: Specifies the end IP address, which cannot be lower than the start-ip-address. If the
argument is not specified, only the start-ip-address is excluded from dynamic allocation. If it is specified,
the IP addresses from start-ip-address through end-ip-address are all excluded from dynamic allocation.
Usage guidelines
The IP addresses of some devices such as the gateway and FTP server cannot be assigned to clients. Use
this command to exclude such addresses from dynamic allocation.
You can exclude multiple IP address ranges from dynamic allocation.
If the excluded IP address is in a static binding, the address can be still assigned to the client.
The address or address range specified in the undo form of the command must be the same as the
address or address range specified in the command. To remove an IP address that has been specified as
part of an address range, you must remove the entire address range.
Examples
# Exclude the IP addresses of 10.110 .1.1 t h r o u g h 10 .110.1.63 from dynamic allocation.
