b.  Identify whether the local port comes up: 
−  If the port comes up, the peer port fails. Replace the peer port with a new port operating 
correctly. 
−  If the port remains in down state, the local port fails. Replace the local port with a new 
port operating correctly. 
4.  If the issue persists, contact H3C Support, and provide the following information: 
<Sysname> display diagnostic-information 
Save or display diagnostic information (Y=save, N=display)? [Y/N]:Y
