Abstract

A smart interface card control method and apparatus are disclosed. The method includes: after a smart interface card is inserted into a smart interface card slot of a host, registering a virtualized management interface with the host by using a protocol stack of a preset type (S 102 ); creating a virtual link, and connecting a baseboard management controller BMC management interface to the virtual link (S 104 ); receiving a management address configuration instruction sent by the host, and configuring a management address of the management interface according to the management address configuration instruction (S 106 ); and receiving a control instruction that is sent by the host by using the management address, and sending the control instruction to the BMC management interface by using the virtual link (S 108 ). According to the foregoing smart interface card control method and apparatus, scalability of the smart interface card can be improved.
