  • Isolation and monitoring mode for problematic data links
    Patent number: 10348553
    Abstract: Techniques for dampening an interface flapping rate between switches in a network environment. An interface of a first switch is designated as being in an active mode in which forwarding activity of the interface is permitted. The interface is determined to exhibit flapping behavior satisfying one or more dampening criteria when in the active mode. An indication is sent to a second switch to isolate the interface. A reply to the indication is received from the second switch. The interface is designated as being in an isolated mode in which health monitoring of the interface is permitted but forwarding activity of the interface is prohibited. The interface is determined to satisfy one or more reinstatement criteria when in the isolated mode. The interface is redesignated as being in the active mode.
