ExtremeXOS has Dynamic Host Configuration Protocol (DHCP) support.
In simple terms, a DHCP server dynamically manages and allocates IP addresses to clients. When a client accesses the network, the DHCP server provides an IP address to that client. The client is not required to receive the same IP address each time it accesses the network. A DHCP server with limited configuration capabilities is included in the switch to provide IP addresses to clients.
