Severe port flapping on CRS328-24P-4S+ and CRS317-1G-16S+

Thu Nov 15, 2018 6:47 pm

Hi

I am running 17 CRS328-24P-4S+ connected to 2 CRS317-1G-16S+ using this SFP S+32LC10D. The 328 boxes are running RouterOS 6.43.2 and the CRS317 boxes are running 6.43.4. I am experiencing that all the ports on the CRS317 are going up and down with anything between minutes to hours apart. It is almost no traffic on the network. I am totally in the dark here, do any of you have any idea what this could be?

Example from log:
17:02:12 interface,info sfp-sfpplus2 link down
17:04:07 interface,info sfp-sfpplus2 link up (speed 10G, full duplex)
17:09:04 interface,info sfp-sfpplus8 link down
17:09:05 interface,info sfp-sfpplus8 link up (speed 10G, full duplex)
17:18:00 interface,info sfp-sfpplus3 link down
17:18:01 interface,info sfp-sfpplus3 link up (speed 10G, full duplex)
17:24:13 interface,info sfp-sfpplus4 link down
17:24:15 interface,info sfp-sfpplus4 link up (speed 10G, full duplex)
17:25:04 interface,info sfp-sfpplus16 link down
17:25:05 interface,info sfp-sfpplus16 link up (speed 10G, full duplex)
17:34:00 interface,info sfp-sfpplus4 link down
17:34:01 interface,info sfp-sfpplus4 link up (speed 10G, full duplex)

Try 6.43.7 and make sure routerboot is also updated.

Sure, i dont see anything about the 317s in the changelog, but i'll try. Will give a new status in about 24h, will see if anything has changed.

Sad to say, but this made no difference.

I am also seeing some link downs on CRS328 switches but the firmware update made them significantly less for me.

Unfortunately not. I sendt them the support files at 22. Nov and did a follow up on 4. Des. Still no reply. Would be great if MT would have a look at this.

From the MikroTik site it looks to me like the S+32LC10D is specifically meant to have the S+23LC10D module on the other end. Are you using the same module on both ends?

I have the SAME EXACT problem. Mikrotik needs to fix this. No problem with 1Gbps SFP but with OWM SFP+ it's hell. I think this could be combination of software and hardware problem with SFP+ modules.

I agree with you assumtion that this is an edge case between the SFP units and the switch. But strangely it only occurs on one of our two CRS317 in the installation.

I am using the paired SFP+ from Mikrotik S+2332LC10D. So yes.
