You observe cyclic redundancy check (CRC) errors on a network port from a node in the cluster.
Which two components would you consider reseating or replacing before you perform actions on the physical port where the errors are reported from the node?
(Choose two.)
When observing cyclic redundancy check (CRC) errors on a network port, it generally indicates issues with physical connectivity. The two main components to consider reseating or replacing are the SFP module and the cable. The SFP (Small Form-factor Pluggable) is responsible for the physical layer of the network port, and any faults in it can lead to CRC errors. The cable is another critical element, as a damaged or improperly seated cable can also result in transmission errors. Addressing these two components first is a common and effective troubleshooting step for resolving CRC errors.
In my experience need reseating/change SPF and cable for CRC errors.
I think the first thing to suspect is SFP & cable.
SFP + Cable - CRC errors points to physical interruptions - AD
