RB5009 SFP+ flapping

Fri May 13, 2022 4:00 pm

I have an RB5009 that has a 10Gb fiber connection to the router in the main rack.
I recently upgrade to the RB5009 because of the 2.5 Gb port and my new comcast device.

Since then, the connection between that device and my CRS317-1G-16S+ is dropping and re-establishing many times.
I recently upgraded everything to 7.2.3 and I thought it had resolved it but it is happening again.

I have just changed the connection speed on both ends to 1gb in hopes that it will help.

Both SFP+ are from the same manufacturer.

This has improved in recent firmware, including the latest 7.3beta40. What are you running?

7.3beta40 made it worse. I need to back rev now.

Did you set the port speed explicitly to 2.5G, autonrgotiate off, making use of the new feature?

If so, which SFP+ module are you using?

This has gotten so bad that i had to run an ethernet cable between two of the switches just to keep network stability.

Need to put a ticket into them.
