Embodiments of the present invention disclose a method, device, and system for dual-uplink tangent ring convergence, where ports on a network device are classified into conjugate ports and non-conjugate ports; when receiving an entry update packet from a first port or perceiving a state change of a first port, if it is determined that the first port of the network device is a conjugate port, the network device clears an MAC entry and an ARP entry that use the first port as an outbound interface and clears all MAC entries that use a non-conjugate port as an outbound interface, in an MAC table and an ARP table of the network device. In this way, a problem of traffic interruption can be avoided because a failure of one dual-uplink tangent ring does not cause an entry of one or more other normal dual-uplink tangent rings to be cleared/updated. |
