Switch provided failover

摘要

A system is configured to: transmit requests to a first device and a second device; receive a first reply from the first device in response to one of the requests; determine an address of the first device based on the first reply; assign a first port to a first network when the first device is a first one of one or more devices that replied to the requests and have a same address as the first device; receive a second reply from the second device in response to another one of the requests; assign a second port to a second network when the address of the second device is the same as the address of the first device; and reassign the second port, from the second network, to the first network when a failure of the first device occurs.

1. A method comprising:
receiving, by a network device, a first message from a first device,
the first device being associated with a particular virtual media access control (VMAC) address; determining, by the network device, that no other message has been received, prior to the first message, from any device associated with the particular VMAC address; assigning, by the network device, the first device to a first virtual local area network (VLAN) based on the first message and based on determining that no other message has been received, prior to the first message, from any device associated with the particular VMAC address; receiving, by the network device, a second message from a second device,
the second device being associated with the particular VMAC address; determining, by the network device, that the first device is already assigned to the first VLAN; assigning, by the network device, the second device to a second VLAN based on the second message and based on determining that the first device is already assigned to the first VLAN; detecting, by the network device, a failure of the first device; and reassigning, by the network device, the second device from the second VLAN to the first VLAN based on detecting the failure of the first device.
