Step 9: Check for SONET 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 so-fpc/pic/port extensive 

Sample Output

user@host# show interfaces so-2/2/0 extensive

Physical interface: so-2/2/0, Enabled, Physical link is Up

What It Means

Check for any error statistics that may appear in the section, line, and path areas of 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).
