两台V890，DB01和DB02，做RAC，经常出现网卡link down/up的情况，网线和交换机口都换过多次；\r\n3月10号又出现警告：\r\nDB01:\r\nMar 10 11:21:22 cmsdb01 genunix: [ID 408822 kern.info] NOTICE: ce2: no fault external to device; service available\r\nMar 10 11:21:22 cmsdb01 genunix: [ID 611667 kern.info] NOTICE: ce2: xcvr addr:0x01 - link up 1000 Mbps full duplex\r\nMar 10 11:30:26 cmsdb01 genunix: [ID 408789 kern.warning] WARNING: ce5: fault detected external to device; service degraded\r\nMar 10 11:30:26 cmsdb01 genunix: [ID 451854 kern.warning] WARNING: ce5: xcvr addr:0x01 - link down\r\nMar 10 11:30:30 cmsdb01 genunix: [ID 408789 kern.notice] NOTICE: ce5: fault cleared external to device; service available\r\nMar 10 11:30:30 cmsdb01 genunix: [ID 451854 kern.notice] NOTICE: ce5: xcvr addr:0x01 - link up 1000 Mbps full duplex\r\nMar 10 11:30:33 cmsdb01 genunix: [ID 408789 kern.warning] WARNING: ce5: fault detected external to device; service degraded\r\nMar 10 11:30:33 cmsdb01 genunix: [ID 451854 kern.warning] WARNING: ce5: xcvr addr:0x01 - link down\r\nMar 10 11:30:36 cmsdb01 genunix: [ID 408789 kern.notice] NOTICE: ce5: fault cleared external to device; service available\r\nMar 10 11:30:36 cmsdb01 genunix: [ID 451854 kern.notice] NOTICE: ce5: xcvr addr:0x01 - link up 1000 Mbps full duplex\r\nMar 10 11:30:37 cmsdb01 genunix: [ID 408789 kern.warning] WARNING: ce5: fault detected external to device; service degraded\r\nr:0x01 - link downsdb01 genunix: [ID 451854 kern.warning] WARNING: ce5: xcvr add--More--(99%)\r\nMar 10 11:30:56 cmsdb01 genunix: [ID 408789 kern.notice] NOTICE: ce5: fault cleared external to device; service available\r\nMar 10 11:30:56 cmsdb01 genunix: [ID 451854 kern.notice] NOTICE: ce5: xcvr addr:0x01 - link up 100 Mbps full duplex\r\nMar 10 12:53:28 cmsdb01 genunix: [ID 408789 kern.warning] WARNING: ce2: fault detected external to device; service degraded\r\nMar 10 12:53:28 cmsdb01 genunix: [ID 451854 kern.warning] WARNING: ce2: xcvr addr:0x01 - link down\r\nMar 10 12:53:43 cmsdb01 genunix: [ID 408789 kern.notice] NOTICE: ce2: fault cleared external to device; service available\r\nMar 10 12:53:43 cmsdb01 genunix: [ID 451854 kern.notice] NOTICE: ce2: xcvr addr:0x01 - link up 1000 Mbps full duplex\r\nMar 10 12:59:23 cmsdb01 genunix: [ID 408789 kern.warning] WARNING: ce2: fault detected external to device; service degraded\r\nMar 10 12:59:23 cmsdb01 genunix: [ID 451854 kern.warning] WARNING: ce2: xcvr addr:0x01 - link down\r\nMar 10 13:01:04 cmsdb01 genunix: [ID 408789 kern.notice] NOTICE: ce2: fault cleared external to device; service available\r\nMar 10 13:01:04 cmsdb01 genunix: [ID 451854 kern.notice] NOTICE: ce2: xcvr addr:0x01 - link up 1000 Mbps full duplex\r\ntected external to device; service degraded kern.warning] WARNING: ce2: fault de--More--(99%)\r\nMar 10 13:06:16 cmsdb01 genunix: [ID 451854 kern.warning] WARNING: ce2: xcvr addr:0x01 - link down\r\n\r\nDB02：\r\n\r\nMar 10 11:22:04 cmsdb02 genunix: [ID 408789 kern.warning] WARNING: ce2: fault detected external to device; service degraded\r\nMar 10 11:22:04 cmsdb02 genunix: [ID 451854 kern.warning] WARNING: ce2: xcvr addr:0x01 - link down\r\nMar 10 12:05:08 cmsdb02 genunix: [ID 408789 kern.notice] NOTICE: ce2: fault cleared external to device; service available\r\nMar 10 12:05:08 cmsdb02 genunix: [ID 451854 kern.notice] NOTICE: ce2: xcvr addr:0x01 - link up 1000 Mbps full duplex\r\n\r\n这类错误是由于网线或者交换机口引起？还是网卡本身的问题？请大虾帮忙啊！

但从硬件上来说，交换机口出问题的可能性比较大。

是什么交换机，交换机的端口的速度是什么？如果100M的交换机可能是会有这样的问题。如果经常有这样的问题，不要使用网络自动匹配的功能，将网卡的速度设固定的。
