We have CRS317-1G-16S+
in our lab (actually it should be already in production but we have a lot of problems with this device)
After delivery we upgraded it RouterOS to latest 6.43.4. No settings, default config removed. Then we switched to SwOS boot, factory SwOS firmware was 2.7, manual upgraded to 2.8. Very simple configuration for testing:
SFP modules installed (all Mikrotik brand):
For testing purpose 5 VLANs was configured (1, 405, 410, 420, 430):
VLAN tab :
SFP5 connected to CSR328-24P-4S+
SFP16 connected to CCR1036-8G-2S+
(to SFP2 trunk port, VLAN Bridge Filtering configured according to latest (after 6.41) manuals)
all other installed SFP are disconnected
RSTP is ON on all ports, IGMP Snooping is ON in System menu and for all VLANs but not VLAN1
After reboot everything is working as it should. Few hours later we not able to connect from PC connected to CCR to web interface of CRS317
. Cooper MGMT port is still working and we are able to connect to CRS317
. All ports on CRS328
are working and web interface accessible.
If we go to "Health" menu of CRS317
when SFP doesn't work already we can see:
But normal state after reboot is:
No errors on ports, nothing else suspicious to mention. This switch doesn't have any logging in SwOS mode. But - Web interface extremely slow.
After reboot CRS317
everything fine again for few hours or minutes. Can't say exact time to "SFP death". But it happened every time.
Something wrong with this device, if it's not able to work as simple switch... is it only me or everyone have such problems with this (amazing on paper) device?
Now we try to disable RSTP on all ports and disable IGMP snooping on all VLANs. 16 hours everything working, SFP links accessible, but web interface became slow again, FAN1 RPM - 14080!!! FAN2 - 0
Any chance it will be fixed soon? Maybe we are doing something wrong? Can anybody help?
PS: From our point of view this device is not ready for production at all, SwOS is kind of Beta testing challenge... We have bunch of this switches and we are going to send them back if solution will not be found soon.
