It will not be seen on directors.Workaround: To avoid loopback test failures, use small values such as 100 for -nframes option with moreiterations.Defect ID: DEFECT000511742Technical Severity: High Probability: LowProduct: Brocade Fabric OS Technology: SecurityReported In Release: FOS7.3.0 Technology Area: EncryptionSymptom: Under very rare conditions, switch goes to faulty state during firmwaredownload.Condition: Due to Ethernet PHY connection issues, link between Control plane and Datapath plane does notcome up.Recovery: Power cycle the switch to recover from the faulty state.Defect ID: DEFECT000514387Technical Severity: High Probability: LowProduct: Brocade Fabric OS Technology: OtherReported In Release: FOS7.3.0 Technology Area: OtherSymptom: Assert encountered during systemverification test on 16G chassis.Condition: This is a very rare occurrence where assert occurs during systemverification test due to a racecondition. This does not occur under normal circumstances.
