By default, no IP address range is configured for dynamic allocation.
Each DHCP address pool can have only one network segment. If an address pool has
already had a segment, the new one configured using the network command replaces
the old one.
Note:
When configuring the IP address range for dynamic assignment in the IP address pool,
make sure the configured mask is consistent with that of the VLAN interface which
functions as the user gateway on DHCP server. If not consistent, the client may fail to
obtain the IP address or fail to use the obtained IP address.
5.3.3 Configure IP Addresses Forbidden in Automatic Allocation
In configuring address allocation by the DHCP server, you should exclude those IP
addresses in use such as IP addresses of gateway and FTP server to avoid address
conflict resulted from allocating one IP address to two hosts.
Perform the following configuration in system view.
