SFP+ port on CCR2004-16G-2S+ suddenly super slow upload

Fri Jul 29, 2022 10:57 pm

Untill 3 days ago, we had no issues with our CCR2004-16G-2S+ router.

Suddenly, everybody upload speed passed from 900+ Mbps to 2-20Mbps with some with jerking in speed.
We tracked it down to that specific sfp-sfpplus1 port that is connected to the rest of our network.
If we connect our network to say Ether2, we have "good" upload speed (300-400Mbps), but still not what we used to have.

We changed the transceiver in sfp-sfpplus1 for another one, but the issue persist. The transceiver is a 10G.
Since this router only has 2 SPF+ ports, if one is dead, it kinda sucks. Especially since we bought this router new, only 5 months ago.

Download speed appear unaffected.
