Dear All,

We are getting huge RX length error on our CCR 10gig SFP port ,kindly help us to fix this.

We have taken following action to fix this but there's no improvement.

1-SFP changed

2-duplex changed

3-L2MTU changed from 1580 to 1598

Do you get FCS errors as well?
SFP Module name ?
Fiber type used ?

Hi, same problem.
CCR1036-8G-2S+EM router and CRS312-4C+8XG-RM switch.
Need to connect them 10gb.
I have SFP+ modules:
Mikrotik S+RJ10
2x Cisco SFP-10G-SR
2x Cisco SFP-10G-LRM
2x Brocade 57-1000117-01

I put any pairs of converters, changed the SFP+ ports to CCR1036, at a speed of 10gb, the RX Length Error accumulates.
As soon as I manually set the speed to 1gb, the errors disappear.
I am currently communicating with technical support, so far they have not given me an answer or a solution to this problem.
Maybe someone knows what this is about? How to solve this problem?
