Dear all,
I have RB2011UiAS-2HnD-IN, latest firmware (v3.14) and the latest version of the RouterOS (v6.12).
Some time ago I had very simple configuration (in a few words):
ether1 - WAN
ether2,3,4 - LAN
LAN ports was in Bridge. All worked perfectly.
But transmissions inside LAN loaded near 50% of CPU and I decided to use Switch Chip Features.
I removed ether3 from Bridge and set master-port=ether2. And here is the most interesting.
In Bridge:
..ether1
..ether2 (connected via switch1 with ehter3)
..ether4
All communications worked properly, access to Internet - OK, transfers between ether2 <--> ether3 no more cause CPU usage.
But when I'm downloading (via windows shared folders) anything in such way: ether2 --> ether4, connection breaks after ~200 mb of data. And then I can't ping ether2 <--> ehter4.
There is internet on all of ether2,3,4. Connection between ether2<-->ether3 still works. But not ether2<-->ether4.
The same is when I'm downloading ether3-->ether4
It seems problem causes automatically added Host (Switch -> Host)
See this (before transmission):
[admin@MikroTik] > interface ethernet switch host print
Flags: D - dynamic, I - invalid
SWITCH MAC-ADDRESS PORTS TIMEOUT DROP MIRROR VLAN-ID
0 D switch1 00:08:9B:C9:AB:7E ether2 3m30s no no 1
1 D switch1 20:89:84:1E:AD:94 switch1-cpu 3m30s no no 1
2 D switch1 4C:5E:0C:3F:F7:74 switch1-cpu 3m30s no no 1
3 D switch1 4C:5E:0C:3F:F7:72 switch1-cpu 3m30s no no 1
After broken transmission:
[admin@MikroTik] > interface ethernet switch host print
Flags: D - dynamic, I - invalid
SWITCH MAC-ADDRESS PORTS TIMEOUT DROP MIRROR VLAN-ID
0 D switch1 00:08:9B:C9:AB:7E ether2 3m30s no no 1
1 D switch1 20:89:84:1E:AD:94 switch1-cpu 3m no no 1
2 D switch1 4C:5E:0C:3F:F7:74 switch1-cpu 3m30s no no 1
3 D switch1 4C:5E:0C:3F:F7:72 switch1-cpu 3m30s no no 1
4 D switch1 00:08:9B:C9:AB:7E ether2 3m no no 0
After some time of inactivity this line disappears and connections work again... until I begin trasmission (ether2/3 ---> ether4)
Is it bug? Or how can I resolve this problem?
