H3C 5500-28F-EI的光电复用的电口25、27不能千兆

这两个端不能千兆，只能百兆，对端交换机千兆，电脑千兆，光纤收发器千兆，网线换了十几根，插其它电口，马上绿灯，显示千兆。现对27端口检查发现Current state: DOWN,现把详细信息发出，请老师看一下，什么情况，怎么解决。 [H3C]dis interface g1/0/7 GigabitEthernet1/0/7 current state: DOWN IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 50da-0097-012d Description: GigabitEthernet1/0/7 Interface Loopback is not set Media type is not sure,Port hardware type is No connector Unknown-speed mode, unknown-duplex mode Link speed type is autonegotiation, link duplex type is autonegotiation Flow-control is not enabled The Maximum Frame Length is 9216 Broadcast MAX-ratio: 100% Unicast MAX-ratio: 100% Multicast MAX-ratio: 100% Allow jumbo frame to pass PVID: 1 Mdi type: auto Port link-type: access Tagged VLAN ID : none Untagged VLAN ID : 1 Port priority: 0 Last clearing of counters: Never Peak value of input: 0 bytes/sec, at 2000-04-26 12:28:49 Peak value of output: 0 bytes/sec, at 2000-04-26 12:28:49 Last 300 seconds input: 0 packets/sec 0 bytes/sec -% Last 300 seconds output: 0 packets/sec 0 bytes/sec -% Input (total): 0 packets, 0 bytes 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Input (normal): 0 packets, - bytes 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Input: 0 input errors, 0 runts, 0 giants, 0 throttles 0 CRC, 0 frame, - overruns, 0 aborts - ignored, - parity errors Output (total): 0 packets, 0 bytes 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Output (normal): 0 packets, - bytes 0 unicasts, 0 broadcasts, 0 multicasts, 0 pauses Output: 0 output errors, - underruns, - buffer failures 0 aborts, 0 deferred, 0 collisions, 0 late collisions 0 lost carrier, - no carrier
