I currently have 4 cisco 6006 switches (A,B,C,D) in a mesh network (except C & D not link together) and 3 Cisco 4510R switches (E,F,G) all links to C (Po1) & D (Po2). switch E,F,G do not interlink each other.
While I was doing a UAT test, I do a continuous ping from the client's side of G to the outside world. Everything goes fine when all equipments is up. But when I power down switch C, I found that sometimes I can ping but somwtimes it will show "request time out." I was wondering what went wrong to the networks because from what I understand, in such a mesh network, by right unstability should not be occurring. I do not know what is wrong and how should I go about with the triubleshotting.
Hope that you guys will be able to help me. Thanks
