•
If you use the network or address range command multiple times for the same address pool,
the most recent configuration takes effect.
•
IP addresses specified by the forbidden-ip command are not assignable in the current address
pool, but are assignable in other address pools. IP addresses specified by the dhcp server
forbidden-ip command are not assignable in any address pool.
To specify a primary subnet and multiple address ranges for a DHCP address pool:
Step
1. Enter system view.
2. Create a DHCP user class and
enter DHCP user class view.
3. Configure the match rule for
the DHCP user class.
4. Return to system view.
5. Create a DHCP address pool
and enter its view.
6. Specify the primary subnet for
the address pool.
7. (Optional.) Specify the
common address range.
8. (Optional.) Specify an IP
address range for a DHCP user
class.
9. (Optional.) Set the address
lease duration.
10. (Optional.) Exclude the
specified IP addresses in the
address pool from dynamic
allocation.
11. Return to system view.
12. (Optional.) Exclude the
specified IP addresses from
automatic allocation globally.
