S-RJ01 - 5 pieces
mangle rules are 60 pieces
rules nat 27
1 pppoe client connection
9 l2tp client connections
Versions 6.45.8, 6.46.5, 6.47beta60.
ALL interfaces fall and after 1-2 seconds rise.
2 to 6 times per day
CPU utilization 1-2%
6 months in no way get rid of interface flapping.
As a test, I transferred the configuration to CRS236-24G-2S +.
The processor was heavily loaded, but no ports fell.
I bought a new CCR1009-7G-1C-1S +.
Exactly the same problem.
Turned in support of Mikrotik. The ticket is still open. There is no solution or support.
In addition to this connector, all routers see incorrectly - LC. And it should be RJ45.
For example, 2011 sees s-rj01 correctly and works fine
