Dhcp Server Forbidden; Dhcp Server Ip-Pool - 3Com S7906E Command Reference Manual

Parameters
low-ip-address: Start IP address of the IP address range to be excluded from dynamic allocation.
high-ip-address: End IP address of the IP address range to be excluded from dynamic allocation. The
end IP address must have a higher sequence than the start one.
Description
Use the dhcp server forbidden-ip command to exclude IP addresses from dynamic allocation.
Use the undo dhcp server forbidden-ip command to remove the configuration.
By default, all IP addresses in a DHCP address pool are assignable except IP addresses of the DHCP
server interfaces.
Note that:
When you use the dhcp server forbidden-ip command to exclude an IP address that is bound to
a user from dynamic assignment, the address can be still assigned to the user.
When you use the undo dhcp server forbidden-ip command to remove the configuration, the
specified address/address range must be consistent with the one specified with the dhcp server
forbidden-ip command. If you have configured to exclude an address range from dynamic
assignment, you need to specify the same address range in the undo dhcp server forbidden-ip
command instead of specifying one IP address.
Using the dhcp server forbidden-ip command repeatedly can exclude multiple IP address ranges
from allocation.
Related commands: dhcp server ip-pool, network, static-bind ip-address.
Examples
# Exclude the IP address range 10.110.1.1 to 10.110.1.63 from dynamic allocation.
