An error occurs when excluded-ip-address is executed

20

The solution to solving errors of IP addresses that cannot be dynamically assigned is as follows:
1. Check whether the dhcp select global command is configured on the VLANIF interface. This command can be used only after the address pool is configured. If the address pool has been configured, run the undo dhcp select global command to delete the configuration.
2. Check whether the range of IP addresses that cannot be dynamically assigned is large, attempt to exclude one IP address and check whether the fault persists. If the fault is rectified, the range of IP addresses that cannot be dynamically assigned is large. Reduce the range.
3. Run the display ip pool command to check whether the IP address status is conflict, expired, or used. If the IP address status is conflict, expired, or used, reclaim the IP address and reconfigure the IP address that cannot be dynamically assigned.
4. Check whether the number of addresses in the address pool exceeds the specifications. You can check the device specification list. If the number of addresses in the address pool exceeds the specifications, delete the address pool and re-create a new address pool.
The device configuration is not performed through command lines. After vrpcfg.zip is exported, batch modify the configuration, and import the configuration to the flash memory. In this case, the system does not display an error message when the number of addresses in the address pool exceeds the specifications.

Methods used to configure the excluded IP address on the AR
During network planning, some IP addresses in an address pool may be used by servers or other hosts, or some clients can be configured with specified IP addresses only because of special requirements. In this case, you need to exclude these IP addresses that cannot be automatically allocated from the address pool, preventing IP address conflicts. Assume that IP addresses in the range of 10.10.10.11 to 10.10.10.20 cannot be dynamically allocated. The configuration on the AR is as follows: - Interface address pool [Huawei] dhcp enable [Huawei] interface gigabitethernet 1/0/1 //Enter the view of the interface connected to the DHCP clients. [Huawei-GigabitEthernet1/0/1] undo portswitch [Huawei-GigabitEthernet1/0/1] ip address 10.10.10.10 24 [Huawei-GigabitEthernet1/0/1] dhcp select interface [Huawei-GigabitEthernet1/0/1] dhcp server excluded-ip-address 10.10.10.11 10.10.10.20 - Global address pool [Huawei] dhcp enable [Huawei] interface gigabitethernet 1/0/1 //Enter the view of the interface connected to the DHCP clients. [Huawei-GigabitEthernet1/0/1] undo portswitch [Huawei-GigabitEthernet1/0/1] ip address 10.10.10.10 24 [Huawei-GigabitEthernet1/0/1] dhcp select global [Huawei-GigabitEthernet1/0/1] quit [Huawei] ip pool global1 [Huawei-ip-pool-global1] network 10.10.10.0 mask 24 [Huawei-ip-pool-global1] excluded-ip-address 10.10.10.11 10.10.10.20
