交换机端口镜像过后的问题

ppp2

发现问题,
如果把核心交换机上的端口镜像功能打开,就会出现经常timed out,
关闭的话,就一点事也没有,
以前都用的好好的,就这两天网老是慢,用科来也查不出原因,
后来就把镜像关了,突然发现没事了,奇怪,
求助~~~~~~~~

基本上24个端口每个端口一个VLAN,
24为上行端口,
2为本机,
红色标记为镜像24端口的进出数据,
取消该项网络正常,
添加该项ping网关时断时续.

注:最近刚出现网络不稳定,无意中发现的,以前没问题

交换机做端口镜像回影响交换机性能的，这个很明显的现象可以直接证明这点的

ppp2

特别声明:

以前做的镜像,一直用着的,都没有问题,不知为什么,前几天刚刚出现这种情况,

孤独的意尹者

那最近的流量是否比以前大呢？以前你有做网络基线数据吗？

fafaaipingping

挂上一段时间 看看

jmhyy

LZ我的CISCO3750这几天也出现像你这样的问题.不知道你解决了没有.
用了一年都没有出现问题,这几天,突然老是丢包.不知道是什么原因.

luxxsys

可能是中了交换机病毒了吧，这几天正赶上病毒发作了。

jmhyy

但是把镜像功能去掉就正常了.
搞得我现在想用科来都用不了了.

zmc837

看看cpu利用率，dis cup

jmhyy

以下是我的:
CPU utilization for five seconds: 5%/0%; one minute: 5%; five minutes: 5%

另外PING CISCO3750这台交换机的时候就不丢包,不管是启用镜像,还是没有启用,都正常.PING其他
机器也正常.
