Took Router 2011 and put into production as a bridge (tower 7 Rocket M5 and a RB912 link), but my colleagues have shared that there are problems like strange lag and ping tests with big packets (65000) don't run on the 100Mbit ports and Giga ports on 100Mbit link (rockets).
Testing from Rocket to RB2011 (5m FTP cable) ping 65000byte - 100% loss
Testing from RB912 to RB2011 (5m FTP cable) ping 65000byte - 0% loss 3ms
Colleagues replace RB2011 whit switch TP-Link 3210 and all running OK
Now the RB2011UAS is in my lab and testings starts
Reset to defaults , put IP on interface and cables
First test (first image):
RB2011UAS --- Giga switch --- Linux router
All test was OK ping from Linux to RB on 65500bytes is 2,7-3,0ms and 0% loss
Second test (second image):
RB2011UAS --100M-8port switch -- Giga switch --- Linux router
Same ping was 100%loss
Then try on 100M ports (port 6-10) has the same problem.
Strange in the whole situation is that the graph shows two-way traffic on RB2011 port and replays on Linux tcpdump, but there are 100% losses!
I tried with different versions of firmware and RouterOS, same results!
Is this hardware bug on 2011 series , because I have two RB2011 and two are held in the same way?
