楼主想用 Cisco SFP-H10GB-CU3M DAC 把 Aruba 2540 交换机(JL357A,固件 YC.16.09.0001)连接到 Cisco Catalyst 9300 交换机上。启用 allow-unsupported-transceiver 之后,这些线缆依然没被识别:show tech transceivers 把该端口列为不支持,LED 闪橙色,日志显示 port 52 Transceiver type not supported in this port。楼主原以为这条命令应该能让任何 DAC 都能用。

  • 硬件: Aruba 2540 JL357A、Cisco Catalyst 9300
  • 光模块: Cisco SFP-H10GB-CU3M DAC
  • 封装形式: SFP+、DAC

现象/报错信息:

port 52 Transceiver type not supported in this port
flashing orange LED
show tech transceivers: unsupported

allow-unsupported-transceiver 只是让交换机愿意去尝试一个模块;HPE 官方文档写明第三方部件不保证能用,支持也可能被拒绝。可以打开调试日志看看这根 DAC 具体是因为什么被拒绝的。
