Command Reference Guide – DHCP Chapter 1 DHCP Server Configuration Commands
1-28
If neither subnet mask nor mask length is specified in this command, the default
subnet mask is adopted.
Description
Use the network command to configure a dynamically assigned IP address range
(where IP addresses will be dynamically assigned to DHCP clients).
Use the undo network command to remove a dynamically assigned IP address
range.
By default, no such IP address range is configured for a DHCP address pool.
Note that you can configure only one such IP address range for a DHCP address pool.
If you execute the network command repeatedly, the new configuration overwrites the
previous one.
Related command: dhcp server ip-pool and dhcp server forbidden-ip.
Example
# Configure the dynamically assigned IP address range 192.168.8.0/24 for the global
DHCP address pool 0.
