Method, network management center, and a related device for configuring a network policy for a virtual port

A method for configuring a network policy for a virtual port, comprising:

• obtaining a media access control (MAC) address of a virtual port;
• sending a request that carries the MAC address, wherein the request is used to request delivering a physical network policy group that is used for configuring the network policy for the virtual port corresponding to the MAC address;
• and
• receiving the delivered physical network policy group, and configuring the network policy for the virtual port corresponding to the MAC address.

A network management center, comprising:

• an obtaining module, configured to obtain a virtual network policy group, a physical network policy group, and a media access control (MAC) address of a virtual port, wherein the virtual network policy group is used by a virtual switch to configure the network policy for the virtual port after being delivered to the virtual switch;
• an associating module, configured to associate the virtual network policy group, the physical network policy group, and the MAC address of the virtual port of a virtual machine (VM) to form a virtual port policy association table;
• and
• a policy delivering module, configured to select a physical network policy group corresponding to a MAC address from the virtual port policy association table, and deliver the physical network policy group to a physical switch, so that the physical switch configures the network policy for the virtual port corresponding to the MAC address.

A physical switch, comprising:

• an obtaining module, configured to obtain a media access control (MAC) address of a virtual port;
• a request sending module, configured to send a request that carries the MAC address, wherein the request is used to request delivering a physical network policy group that is used for configuring a network policy for the virtual port corresponding to the MAC address;
• and
• a policy receiving module, configured to receive the delivered physical network policy group, and configure the network policy for the virtual port corresponding to the MAC address.
