Can a switch allocate IP addresses to APs

8

A DHCP server can allocate IP addresses to APs if the DHCP server supports Option 43. Any device can function as a DHCP server if APs can obtain their IP addresses and the AC' IP address from the device in Layer 3 networking. Ensure that APs can ping the AC' source IP address.

Can an AR allocate IP addresses based on secondary IP addresses
All AR models allocate IP addresses based on the primary IP address, regardless of whether the interface or global address pool is used. The AR cannot allocate IP addresses based on the secondary IP address, that is, user terminals cannot obtain IP addresses on the same network segment as the secondary IP address.

Static DHCP binding supported by the AR
All AR models of all versions can allocate fixed IP addresses to clients.

Can a DHCP server (BAS, high-end router, or high-end switch) allocate IP addresses to APs
A DHCP server can allocate IP addresses to APs if the server supports Option 43. Any device can function as a DHCP server if APs can obtain their IP addresses and ACs' IP addresses from the device. Ensure that APs can ping the ACs' IP addresses.

IP address allocation based on sub IP address
All S series switches except S1700 switches in all versions assign IP addresses in interface address pools and global address pools based on primary IP addresses, but not secondary IP addresses. That is, users cannot obtain IP addresses on the same network segments as secondary IP addresses.

Can a static IP address be allocated to different clients
S series switches except S1700 switches do not assign IP addresses in use to clients. Before assigning an IP address to a client, a switch functioning as the DHCP server sends ping packets to the IP address to prevent IP address conflicts. You can run the dhcp server ping { packet number | timeout milliseconds } command in the system view to specify the maximum number of ping packets to be sent by a DHCP server and the maximum response time of a ping packet. If there is no response to the ping packet within the maximum response time, the DHCP server continues to send ping packets to this IP address until the number of ping packets reaches the maximum value. If there is still no response, this IP address is not in use and the DHCP server assigns the IP address to a client. This ensures that the IP address assigned to the client is unique.
