Embodiment Construction

[0050] The invention provides a method for binding a server MAC address and an uplink port, pre-configuring an uplink port group, an IP address pool, and a layer-3 interface IP, and sending a detection message for querying the MAC address according to the server IP address in a virtual local area network; the detection The destination IP address of the message belongs to the address in the pre-configured IP address pool; when the port in the received probe response message belongs to the pre-configured uplink port group, and the source MAC or port is the same as that contained in the Layer 2 forwarding table of the switch When the MACs or ports in the table entries of the same virtual local area network are not equal, the MAC or port corresponding to the virtual local area network in the layer 2 forwarding table is updated to the MAC or port corresponding to the probe response message.

[0051] The prior art adopts a static configuration method, but there is still a problem tha...

Abstract

The utility model discloses a method of binding a server MAC address to an uplink port, which an uplink port group, an IP address pool and a three-layer interface IP for VLAN are pre-configured. The utility model comprises: a detecting message is sent to inquire an MAC address according to a server IP address in a virtual local network; the sever IP address of the detecting message belongs to a plurality of addresses in the preset IP address pool; when a port in a detecting response message received belonging to the preset uplink port group and the source MAC address or the port is not equal to the MAC address or the port in a plurality of list items comprising the virtual local network in a switch second layer forwarding table entry, the MAC address or the port corresponding to the virtual local network in the switch second layer forwarding table is updated to be the MAC address or the port corresponding to the detecting response message. The utility model also discloses a corresponding apparatus. The utility model can automatically realize the update of binding between a port and a server MAC address and can adapt to an annular network.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method and device for binding a server MAC address and an uplink port. Background technique [0002] A typical network structure diagram of a computer accessing a server through the network can be as follows: figure 1 shown. [0003] As shown in the figure, the network structure includes servers 1 to 3, switches 1 to 3, and computers 1 to 8. Wherein, switch 1 is an aggregation layer switch, and switches 2 and 3 are access layer digital subscriber line access multiplexers (Digital Subscriber Line Access Multiplexer, DSLAM) or layer 2 switches. Switch 1 has 5 ports, among which ports 1 to 3 are connected to servers 1 to 3 respectively. Assume that the Media Access Control (MAC) addresses of servers 1 to 3 are respectively MAC1 to MAC3, and the Internet Protocol addresses (Internet Protocol, IP) addresses are respectively IP1 to IP3. Also included in the figure are s...
