When an S5500-EI Ethernet switch works in the interface address pool mode as a DHCP server, the
only gateway address it can assign to a client is the primary IP address of the interface.
Enabling the Interface Address Pool Mode on Interface(s)
If the DHCP server works in the interface address pool mode, it picks IP addresses from the interface
address pools and assigns them to the DHCP clients. If there is no available IP address in the interface
address pools, the DHCP server picks IP addresses from its global address pool that contains the
interface address pool segment and assigns them to the DHCP clients.
