I've been trying to get a 10 Gbits link up and running for some time now, unfortunately the connection is flapping with an intervals of some secounds.
Hardware setup
- Router: CRS326-24G-2S+ with SwOS 2.13 and temperature around 73 deg.
SFP+ Module Router: 10Gtek 10GBase-LR (Mikrotik compatible FW)
SFP+ Module Intel-Card: 10Gtek 10GBase-LR (Intel compatible FW)
Intel X520 PCIE with 82599EN Chipset from China, Firmware (EFI: 7.9.0, PXE: 2.4.45)
Tests performed so far:
CRS326-24G-2S+ Slot1 Loopback via singlemode-fibre: stable
CRS326-24G-2S+ Slot1 to Slot2 via full in-house singlemode-fibre cabling (so cable test included): stable
Intel X520 Slot1 Loopback via singlemode-fibre: stable
Both connected and 1 Gbit/s (with and without flow control): stable
Both connected and 10 Gbit/s (with and without flow control): flapping
I'm running out of ideas on what else I could test. Unfortunately, the support can't help me either. Are there any suggestions from your side?
Best regards,
Stefan
