Hi, I made the installation of a MX250 but I had a problem with the Internet port with a SFP-TX module - not possible have a link - I tested the SFP with another MX and SFP is OK - we change the MX250 with a new one = same problem - the uplink is connected to a Cisco router - I have this configuration with another customer and it works fine - any idea if it is a known problem ?
