Step 7: Check for Interface Error Statistics
Purpose
Persistent interface error statistics indicate that you need to open a case with JTAC.
Action
To check the local interface for error statistics, use the following JUNOS CLI operational mode command:
user@host>
show interfaces t3-fpc/pic/port:channelextensive.
NOTE: For a list of interface types associated with the Channelized OC-12 IQ interface, see Channelized Intelligent Queuing Interface Naming.

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 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).
