Abstract

Embodiments of the present invention provide a virtual port monitoring method and apparatus. The virtual port monitoring method includes: intercepting a packet received and/or sent by at least one mirror source virtual port; and when the packet received and/or sent by the at least one mirror source virtual port is intercepted, mirroring the packet to the mirror destination virtual port, so that a monitoring virtual machine monitors the at least one mirror source virtual port according to the mirrored packet received from the mirror destination virtual port. The virtual port monitoring method and apparatus provided in the embodiments of the present invention implement the monitoring on packets among multiple virtual machines of a same physical server, and improves the reliability and security of a system.

3. The virtual port monitoring method according to claim 1, wherein before the intercepting the packet, the method further comprises:

according to a received configuration parameter, configuring at least one virtual port as the mirror source virtual port, configuring a virtual port other than the at least one virtual port as the mirror destination virtual port, and setting a mirroring relationship between the at least one mirror source virtual port and the mirror destination virtual port, and a mirroring mode of each mirror source virtual port, wherein the mirroring mode is configured to implement one of the group consisting of;

(a) receiving and sending a mirror, (b) receiving the mirror, and (c) sending the mirror.

4. The virtual port monitoring method according to claims 1, further comprising:

parsing packet header information of a first packet received from a physical port, obtaining a first destination address, and sending the first packet to a virtual port corresponding to the first destination address.

5. The virtual port monitoring method according to claims 1, further comprising:

parsing packet header information of a second packet received from a virtual port, obtaining a second destination address, if the second destination address corresponds to a virtual port, sending the second packet to the virtual port corresponding to the second destination address, and if the second destination address corresponds to no virtual port, sending the second packet to a physical port.

6. A virtual port monitoring method, comprising:

receiving a mirrored packet from a mirror destination virtual port; and

according to the mirrored packet, monitoring at least one mirror source virtual port, wherein the mirrored packet is received and/or sent by the at least one mirror source virtual port.

7. The virtual port monitoring method according to claim 6, wherein:
