DHCP over InfiniBand
IBM
An InfiniBand network uses a link-layer addressing scheme that is 20-bytes long. This is larger than the 16-bytes reserved for the hardware address in DHCP/BOOTP message. The above inequality imposes restrictions on the use of the DHCP message fields when used over an IP over InfiniBand(IPoIB) network. This document describes the use of DHCP message fields when implementing DHCP over IPoIB.
