Abstract: A Slow Protocol packet processing method and a related apparatus, where the method includes receiving, by a network device, a first Slow Protocol packet, determining, based on port information of a port of the network device receiving the first Slow Protocol packet, that a negotiation process is already completed between the network device and the transmit end device, querying, based on device information of the transmit end device carried in the first Slow Protocol packet, whether a device information base stored by the network device in the negotiation process includes the device information of the transmit end device, and identifying the first Slow Protocol packet as a valid packet in response to a result that the device information base includes the device information of the transmit end device.

Abstract: A traffic forwarding method includes determining, by a first network device, a first address resolution protocol (ARP) entry of the access device, where the first ARP entry is used to indicate a mapping relationship among a media access control (MAC) address, an Internet Protocol (IP) address, and an egress port, the egress port includes a standby egress port, and the first network device is connected to the protection link through the standby egress port, receiving traffic sent by a network side, determining whether a fault exists in the first multi-chassis link aggregation group (MC-LAG) link, and when the first network device determines that a fault exists in the first MC-LAG link, sending the traffic to the second network device through the protection link based on a standby egress port number in the first ARP entry, where the standby egress port number is used to indicate the standby egress port.

Abstract: A packet processing method includes sending, by the first provider edge (PE) device, a Media Access Control (MAC) entry update packet to a third PE device when a port of a first PE device that is connected to a customer edge (CE) device is switched from an activated state to a deactivated state, wherein the MAC entry update packet is sent to trigger the third PE device to delete a first MAC entry whose packet forwarding destination address is the first PE device, generating, through learning, a second MAC entry whose packet forwarding destination address is a second PE device, and forwarding a packet based on the second MAC entry.

Abstract: A virtual extensible local area network (VXLAN) packet forwarding method, device, and system, where the method includes setting, by a local VXLAN tunnel end point (VTEP) device based on a priority of a VXLAN tunnel, tunnel states of at least two VXLAN tunnels coupled to the local VTEP device, sending the tunnel states of the VXLAN tunnels to at least two peer VTEP devices, where the at least two VXLAN tunnels are in a one-to-one correspondence with the at least two peer VTEP devices, and separately confirming, by the at least two peer VTEP devices, the received tunnel states of the VXLAN tunnels. A VXLAN tunnel in an active state is in a working state, and a VXLAN tunnel in an inactive state is in a non-working state, thereby improving a redundancy protection capability of a VXLAN network.
