Check for Fast Ethernet or Gigabit Ethernet Interface Error Statistics
Purpose
Persistent interface error statistics indicate that you need to open a case with the Juniper Networks Technical Assistance Center (JTAC).
Action
To check the local interface for error statistics, use the following Junos OS CLI operational mode command:
user@host> show interfaces (fe-fpc/pic/port | ge-fpc/pic/port) extensive
Sample Output
user@router> show interfaces ge-7/2/1 extensive Physical interface: ge-7/2/1, Enabled, Physical link is Up

Meaning
Check for any error statistics. There should not be any input or output errors. If there are any persistent input or output errors, open a case with the Juniper Networks Technical Assistance Center (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).
