@JKnott said in Netgate 6100 SFP+ connection error rate of 0.0055%. Should I be worried?:

Is that your WAN or LAN? While there's no problem with jumbo frames on the LAN, assuming other devices can handle them, you shouldn't be sending them to the WAN. PfSense should be sending ICMP too big messages when a jumbo frame tries to leave your LAN. You shouldn't be using jumbo frames on the WAN side, with the possible exception of if you're on Internet2.

It's my LAN and I do use Jumbo frames on that (carefully). However, the jumbo frames are restricted to two VLANs neither of which are configured on the NetGate so those frames should actually never reach the unit. I think that MTU is a hangover from an older config; I will set it back to the default.

However, in my current setup the LAN is now ix0 and it has an MTU of 1500.
