I recently bought several Mikrotik devices. I have massive performance problems with all of them.
I will begin with the brandnew switch CRS112-8P-4S.
All devices in network are checked with nagios. The ping to switch CRS112 fails with packet loss.
- the firmware on all Mikrotik devices is 6.42.3
- a ping from a hAP ac to the CRS results in timeout for the first 7-10 pings, then the pings work
- I have ping the switch from other devices with the same result.
- a ping between two hAP ac are ok
- the switching power seems to be ok, the connected computers can send and receive with the full bandwith of 1GBit.
- a bandwith test between two hAP ac is ok and I have full bandwith
- a bandwith test between a hAP ac and the CRS112 results in a low bandwith of max 100MBit
- in this case the cpu load of the CRS112 is at 100%
What can I do for a good performance of the device with working pings???
And here is the configuration (based on a clean device):
Code: Select all
# jun/18/2018 22:23:18 by RouterOS 6.42.3
# software id = T5VV-CUSH
#
# model = CRS112-8P-4S
# serial number = 84CAxxxxxxxx
