System and method for rapid VLT connection failure handling

摘要

A system and method for rapid virtual link trunk connection failure handling includes receiving a packet at a first network switching unit where the packet is to be forwarded to a second network switching unit, detecting a failure in a network connection between the first network switching unit and the second network switching unit and associated with a first LAG of the first network switching unit, determining a second LAG associated with an inter-chassis link (ICL) as a failover LAG for the first LAG, redirecting the packet to the second LAG, altering the packet to set a redirection status bit to a logic value, and forwarding the altered packet using the ICL.

1. A method of connection failure handling, the method comprising:
receiving a packet at a first network switching unit, where the packet is to be forwarded to a second network switching unit; detecting a failure in a network connection between the first network switching unit and the second network switching unit, the network connection being associated with a first link aggregation group (LAG) of the first network switching unit; determining a second LAG as a failover LAG for the first LAG, the second LAG being associated with an inter-chassis link (ICL); redirecting the packet to the second LAG; altering the packet to set a redirection status bit to a logic value, wherein the logic value indicates that egress port filtering is not to be applied to the packet; and forwarding the altered packet using the ICL.
