Hi all!
I have a rb5009 connected to a AP with 2.5G on eth 1.
On a “normal” day, I can see more than 20 entries saying
-interface.info - ether1 link down
-interface.info - ether1 link up (speed 2.5G, full duplex)
this entries appears within 1 or 2 seconds…
What I should do?!?!?
Should I start to be worried with this? RMA?
It could be either of devices.
But it could be the cable between the two devices. Ideally you’d check the cable using a professional UTP cable tester to verify that the cable is made according to specs (also frequency response and crosstalk, these tend to become a problem with high-speed links). Even if cable is OK (e.g. cat7), the termination (in patch panel or wall jack) could be done in sub-standard way, and testing it with professional tester is the only way to find that out.
Many thanks for you promptly reply.
Would you recommend any brand?
I only have experience with one particular model (some not-so-recent model by Fluke), so my recommendations aren’t very relevant.
