Configuring dynamic address allocation for an extended address pool
Extended address pools support dynamic address allocation only.
When configuring an extended address pool, you need to specify:
Assignable IP address range
Mask
After the assignable IP address range and the mask are specified, the address pool becomes valid.
Follow these steps to configure dynamic address allocation for an extended address pool:
To do… | Use the command… | Remarks |
|---|---|---|
Enter system view | system-view | — |
Enter extended address pool view | dhcp server ip-pool pool-name extended | — |
Specify the IP address range | network ip range min-address max-address | Required Not specified by default. |
Specify the IP address mask | network mask mask | Required Not specified by default. |
Specify the IP address range for the DHCP clients of a specified vendor | vendor-class-identifier hex-string&<1-255> ip range min-address max-address | Optional Not configured by default. |
Specify the address lease duration | expired { day day [ hour hour [ minute minute ] ] | unlimited } | Optional One day by default. |
Exclude IP addresses from dynamic allocation | forbidden-ip ip-address&<1-8> | Optional Except IP addresses of the DHCP server interfaces, all addresses in the DHCP address pool are assignable by default. |
![[NOTE: ]](images/note.png) | NOTE: Excluded IP addresses specified with the forbidden-ip command in DHCP address pool view are not assignable in the current extended address pool, but are assignable in other address pools. | |
