1. A system for link aggregation in a network, comprising:
a subnet manager (SM) to:
responsive to a request to add a port of two or more physical ports or of other physical ports to a link aggregation (LAG) mode, determine that the port of the two or more physical ports or of the other physical ports is available to join the LAG mode,
update or establish the LAG mode by mapping at least one virtual network address to two or more physical network addresses of the two or more physical ports or of the other physical ports of a host machine, and
communicate configuration information to include the mapping by the SM, using management datagram (MAD) messaging, to at least one switch; and
at least one subnet management agent (SMA) to communicate the configuration information with the SM, the configuration information to enable the at least one switch to configure a forwarding table based in part on the mapping and to enable the host machine to communicate with other host machines using the at least one switch and the at least one virtual network address.
