Static DHCP binding error on S series switch
For S series switches (except S1700 switches), if the message "Error: The static-MAC is exist in this IP-pool" or "Error: The IP address's status is error" is displayed when you configure a static DHCP binding entry, the configuration will fail. The failure occurs because the IP address to bind has been assigned to a client, and an internal mapping entry has already been created on the switch. In this case, you can run the reset ip pool { interface pool-name | name ip-pool-name } { start-ip-address [ end-ip-address ] | all | conflict | expired | used } command in the user view to manually reclaim the IP address in the address pool, and configure a new static binding entry.

Number of supported static DHCP binding entries on S series switch
S series switches (except S1700 switches) support the static DHCP binding configuration. When configuring static DHCP binding, ensure that IP addresses to be bound exist in a DHCP address pool. If you want to know the maximum number of static DHCP binding entries that can be configured, send an email to e_online@huawei.com.
