Hi, I have a strange situation about the span.
The scenario is that on a 6006, three span source ports are span to two span destination ports. There is communication traffic between the two span destination port. All the ports located on the same 6006.
source port 1 |------| destination port A----->Host A
source port 2 | 6006 |
source port 3 |------| destination port B----->Host B
It works fine normally. But randomly, after couple of weeks running, host A(B) can't communicate with host B(A). And in the same time, host A or host B can still communicate with other ports. We verify above situation with ping command on host A and B.
Can anyone give me a recommendation about the issue, or how to troubleshoot it?
