Re: 100g PCS Errors

What is the device on the other side of the MX204 100G link.   We've had some incrementing PCS errors on 100G links 
when the other side was a Juniper PTX1000 using port et-0/0/25.   Using a different port on the PTX1000 resolved the 
incrementing PCS errors.  We opened JTAC cases for two incidents and a root cause was never found.

I would assume this is not normal behavior, but I haven't used 100g 
before. Do others see high error rates on their 100g optics?
