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

You have to change switch port until you find the correct sequence that not flap.. good luck!
Mk switch @10gbps are not reliable at the moment

Switch to SwOS
Use it with no flapping
ok, you can also buy another vendor switch, but I don't think that it was the question...

CRS326-24S+2Q+RM @10gbps have the same problem of crs317.. port flapping, link down.. you have 24 ports but you have to do a lottery moving your link, hoping to found a working solution.. (yesterday: 10Gbps Dac to hpe server nic, on port 5 NO LINK, on port 7 flapping link, on port 9 OK).. very disap...

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

I changed 2 317 with 2 326-24+
The link with all 328 and between 326-24+ are now fine @10Gbps
One link with 326-24G still flap and needed to be set @1Gpbs :-(
Better then before, but seems to be not fully resolved.

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

as MK support said: "if possible, please, consider using CRS309-1G-8S+ as replacement in similar applications to decrease probability of encountering this issue."

Very bad service, client try to use Ubq to replace all CRS328.
Hi gentrice, we are angry too, but the problem we are talking here is on crs317.. what kind of problem do you have on crs328?

You have to check it on 328 side, looking for disconnections or rstp recalculation

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

Mikrotik support tell us that the problem is well known and that they don't have ETA for the resolution.
Their official workarround is to downgrade links to 1Gb or use switchos on 317
I hope that someone take care about this terrible bug!!

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

After we switched on the CRS317-1G-16S+ to SwitchOS 2.9
5 days without port flapping. :)
Hi roggles, still stable with SwitchOs?

Me too.. 317 - Ccr 10Gb mk Dac ok 317 - 326 10Gb mk S+85DLC03D ok 317 - 328 10Gb mk Dac flapping The strange thing is that for over one month all worked fine, after that, without any change, the flapping began. Forcing the Dac to 1Gbps stop the flapping immediatly, now we are monitoring it, but we n...

IEEE 802.1Qbb

Hi,
are the tx-flow-control and rx-flow-control the mikrotik implementation of IEEE 802.1Qbb?
IEEE 802.1Qbb is a must-have for the RoCE (RDMA over Converged Ethernet) that could be used with 10Gbe on CRS317-1G-16S+RM

Thanks
Alessandro
