  • Methods and systems with enhanced robustness for multi-chassis link aggregation group
    Patent number: 9264302
    Abstract: A method implemented for a link aggregation group is disclosed. The link aggregation group contains a local interface and a remote interface. The local interface is a logical interface formed by a plurality of network elements including a local network element and a peer network element. The local network element communicates with the peer network element through an inter-peer link. The method starts with determining that the local network element is active by checking that an aggregate state of the links coupled to the local network element is active. The method continues with detecting an anomaly of the active links and sending a notification to the peer network element about the anomaly. Then method continues with receiving an activation confirmation that the peer network element is ready for switching and switching traffic from the active links to the inter-peer link in response to receiving the activation confirmation.
