一块Mellanox ConnectX-3 40GbE网卡,通过Mellanox QSFP无源铜缆(MC2210126-005)连接到一台Dell PowerConnect 8164(固件5.1.4.5),出现了短暂几秒的link-up事件,之后就一直link-down。同样的线缆网卡对网卡直连时能正常工作,Dell以线缆未经过他们交换机测试为由拒绝提供支持。另一位用户在PowerConnect 8024F(只用Dell自家SFP+线缆)和Brocade 8000上也报告了同样的问题。

把Dell交换机升级到6.x固件,并针对SFP和QSFP模块启用service unsupported-transceiver,这是Dell社区里讨论的方案;结果未经确认。
