Has anyone experienced an issue getting CRC errors whole using CPAK-100G-LR4 with CFP2-to-CPAK port adapter?
I am seeing lot of CRC errors on HundredGig interface connected to CPAK-100G-LR4 using CFP2-to-CPAK port adapter on A9K-MPA-1X100GE of A9K-MOD200-TR modular card. We tried changing the CPAK, Fiber cable and cleaned it but still giving the errors.
If we move the connection to old module "A9K-1X100GE-TR" and sfp "CFP-100G-LR4" errors are not seen.So its not the cable or other end. so wondering something is causing from CFP2-to-CPAK port adapter setup.
