[已解决]Cisco6509为什么镜像不了

hellpup · 发表于 2009-1-2 16:56:21

有个设备cisco6509，很奇怪做镜像的时候源端口有流量的时候，目标端口就是没复制过来
6509(config)#monitor session 1 source interface fa5/1
6509(config)#monitor session 1 destination int fa5/9
6509#sh monitor
Session 1
---------
Source Ports:
RX Only:    None
TX Only:    None
Both:       Fa5/1
Source VLANs:
RX Only:    None
TX Only:    None
Both:       None
Destination Ports: Fa5/9
Filter VLANs:    None

下面是端口的状态，可以看到源端口收发都有数百个包/秒的时候，目标端口都是零，请问有无人知道这是什么回事。
相同指令在2950上面测试过能正常镜像，不知道这个6509有什么问题

没用过cisco的6509 ，做监听的时候不用选择in和out吗？在网上搜索6509是要配置in和out的。另外fa 5/9这个接口也没up啊

hellpup · 发表于 2009-1-2 22:12:27

拿另外一个2950输入相应指令对比，之前的是monitor下的端口状态，后面的是取消镜像后的端口状态，可以看到物理线路是没问题的
line protocol is down (monitoring)是cisco正常的镜像端口的状态

顶起来没有人能帮忙么？

换一对接口试试

hellpup · 发表于 2009-1-4 12:29:09

接口换过了也拿过笔记本直接接到另外的口源口也换过但还是同样

公爵兰 · 发表于 2009-1-4 16:33:27

6500必须指定RX or TX，不像2900、3500等只支持RXandTX。

hellpup · 发表于 2009-1-4 19:11:19

6509#sh monitor
Session 1
---------
Source Ports:
RX Only:    None
TX Only:    None
Both:       Fa5/1
Source VLANs:
RX Only:    None
TX Only:    None
Both:       None
Destination Ports: Fa8/3
Filter VLANs:    None

默认用了both，而且也测试过手动指定tx 或者rx 也是收不到包

没用过cisco的65 帮不了你了，

你先确定你板子上的这个接口有没有SPAN的功能

还有就是检测端口的flowcontrol有没有开启

C6509-1#sh inter g7/23 flowcontrol ?

谢谢NGNWAY的回复了
不知道你的6509是什么版本
我为了解决这个问题升了一个c6sup22-psv-mz.121-27b.E4 结果crash了两次后恢复了原来的版本
不过问题还是解决了大概猜测是因为备用模块状态不正常所造成
真正解决的过程就是插拔了一次备用模块 reload后发现可以正常镜像
