Dell的SFP DAC在Catalyst 9500-48Y4C上被判为不支持而禁用;Cisco SFP-H25G-CU3M能用

楼主用一根Dell L56SF018-SD-R 3米DAC(DAC-SFP-3M)把一台Dell服务器接到Cisco Catalyst C9500-48Y4C(IOS XE 17.9.3)上。这根线缆不在Cisco的光学兼容矩阵里,'show interface status'把端口TwentyFiveGigE1/0/35显示为err-disabled。日志里有'%TRANSCEIVER-6-INSERTED: C1/0: iomd: transceiver module inserted in TwentyFiveGigE1/0/35',紧接着是'%TRANSCEIVER-3-NOT_SUPPORTED: C1/0: iomd: Detected for transceiver module in TwentyFiveGigE1/0/35, module disabled'。全局开启'service unsupported-transceiver'并配置'fec cl108'都没有任何变化。楼主问这根Dell线缆有没有什么变通办法。
