Hi, everyone,
I have strange problem on juniper ex3300. It's located in ring of switches (also junipers) that are in spanning tree domain( MSTP).
Few weeks ago was noticed that when topology of mstp changes switch ex3300 don't display in "show spanning-tree bridge" new changes of topology. Number of topology changes don't increase. And "Time since last topology change" don't reset counter. And after such changes in topology I saw great increasing of strange traffic in ring of switches, also on blocked by STP links. Only restart of this switche help to remove this traffic.
Version of junos was 12.2R8.5. Then we updated version to stable 12.3R12.4. But problem still exists.
Today I've tested that if I diable stp enabled link on ex3300 topology change not displays. And by log there is everything fine, I see work of topology change machine. And also today I've checked that "restart ethernet-switching" can help to resolve problem with strange traffic. It restart STP too.
Do some meet this problem? And what can I do to resolve it?
