如果可以做Debug,可以做个debug查查原因. (如果是重要核心网络,请慎用)
1. debug platform packet all receive buffer
2. show platform CPU packet buffered
3.get the summary for source and destination port,and src and dst MAC address

果断的应该有2层环路~
K2L2 Address Table R + K2FibAdjMan Host Mov 这两个都是在说2层的事,一个是mac地址表,一个是说FIB 的邻接表。。。
1、配个mac notification,看看是不是有大量的mac地址在move、change
2、检查一下topo内几台设备的stp是否正常(一定要在high cpu时做)
3、debug platform packet all receive buffer,这个命令一定要在high cpu的时候做才有意义,另外,不用担心这个命令会增加cpu负载。这个命令和传统的debug是不一样的,可以放心使用。随后,show platform CPU packet buffered 来查看debug的结果。
4、如果还有问题,请联系Cisco TAC,开case,TAC会帮您解决。
