Performance issues when using LACP across multiple NPMsSymptoms:
Since each packet for a single flow may reach another NPM, the NPMs have to re-classify the flow and this is causing significant performance impact. The IEEE specification for LACP requires that all frames for a given stream must be transmitted out of a single interface.
X-series is transmitting frames consistently out of the same interface for a specific uni-directional flow. Note that the port selection might be different for the reverse flow, i.e. each LACP station might select another link from the LACP bundle to transmit frames for that particular bi-directional flow.
Contact the vendor of the switch to provide a solution.
