  • Detecting VLAN registration protocol capability of a switch in a computer network
    Patent number: 9397858
    Abstract: In particular embodiments, a first switch implementing a first virtual local area network (VLAN) registration protocol and connected to a first end of the trunk detects whether a second switch connected to a second end of the trunk implements the first VLAN registration protocol. In an embodiment, the second switch may send an unsolicited message to the first switch indicating the VLAN registration protocol implemented by the second switch. The first switch may then determine the VLAN registration protocol implemented by the second switch. Alternatively, the first switch may send a solicited message to the second switch. By receiving a response to the solicited message, the first switch can determine that the second switch implements the first VLAN registration protocol. In response to determining that the second switch implements the first VLAN registration protocol, the first switch may enable a pruning technique in accordance with the first VLAN registration protocol.
