SFP Does Not Recover After Disconnect

SwOS

I have a RB260GS hooked to a Cisco 3550-12G.

I am using the single mode dual fiber SFP S-31DLC20D and am running version 1.10.

The issue I have is that when the Cisco unit is rebooted or the fiber is disconnected, the link will not come back unless I power cycle the RB260GS.

For the record, the SFP light comes back, but the Cisco unit shows no link and the link does not come back until I power off the RB260GS and power it back on. Then everything is fine.

Any ideas? Is there a setting I am missing? I am deploying hundreds of these and can’t have them all go offline just because we drop power in the Central Office. When power is restored, these links need to come back without having to contact/visit every site and power cycle the equipment. (Kind of important when you have over 1,000 sites connected)

I’d be happy with a simple watchdog on the switch that runs every five minutes automatically power cycles it if it misses 5 ICMP responses.

Settings are in attached JPG.

Cisco Settings are as follows:

interface GigabitEthernet0/2
interface GigabitEthernet0/1
 description Mikrotik SFP Test Port
 switchport trunk encapsulation dot1q
 switchport mode trunk

Try version 1.9. For now (for me) working fine.
1.12 - i is still testing.

I have observed the same with 260GSP and RB2011 on the other side. Have to reboot at least one of the equipment’s to get it working.
And also “auto negotiation” has to be switched off to get the link working. Did you disable auto negotiation as well??
& Mikrotik has habit of asking back so many things if you ask them for support.
These r simple things which they can replicate on a bench test.
Nothing about specific scripting or configuration just simple powering up devices and put to test.

Please mikrotik solve this.

I’ll try 1.9 and get back to you.

I think they will have a general problem with SFP and RB260GS!!!

RB260GS - SFP Module - Not working - no RX just TX

That is so so annoying!

Whe have currently 30 Switches in the field and have 80 pcs encamped.
We will immediately stop deploying them if Mikrotik is not able to stop this problem.
