		<description><![CDATA[近期在实施一工程。期中使用了一台S7510E与几台Cisco 3550的光口做端口聚合。聚合做好后。&#160;&#160;&#160; 有时出现整个片区断网的情况。查端口状态为err-disable。有时手工的在3550端将端 口shutdown再no shutdown后。正常。 经查这种情况可能有6种情况引起。 1、聚合协议不匹配 2、双工不匹配、 3、BPDU 4、UDLD (cisco 私有协议） 5、链路抖动 6、Keeplive loopback。 经分析。在这儿&#160; 聚合协议不匹配与双工不匹配首先排除。因为查看两端均为1G、双工。再从日志上有CNTR-3-LOOP_BACK_DETECTED: Keepalive packet loop-back detected on GigabitEthernet0/2.. 解决方法：停用现3550上面的Loopback。&#160;&#160;&#160; 再做观察。&#160; 目前为止末发现异常。&#160; 不过还需要继续观察。 随附资料: 交换机出现err-disable的原因及解决方法 导致交换机接口出现err-disable的几个常见原因： 引用 1. EtherChannel misconfiguration 2. Duplex mismatch 3. UDLD 4. Link-flap error 5. Loopback error 6. Port security violation 第一个当F EC两端配置不匹配的时候就会出现err-disable。假设Switch A把FEC模式配置为on，这时Switch A是不会发送PAgP包和相连的Switch B去协商FEC的，它假设Switch B已经配置好FEC了。但实事上Swtich [...]]]></description>
