Persistent interface error statistics indicate that you need to open a case with JTAC.
To check the local interface for error statistics, use the following JUNOS CLI operational mode command:

Meaning
Check for any error statistics that may appear in the output. There should not be any input or output errors. If there are any persistent input or output errors, open a case with the JTAC at support@juniper.net, or at 1-888-314-JTAC (within the United States) or 1-408-745-9500 (from outside the United States).
