At a command line prompt, type ping DNSorIP (where DNSorIP is the

 

 

 

 

switch’s DNS name or IP address) and press ENTER.

 

 

If a “Reply from…” or “...is alive...” message appears, the devices can

 

 

communicate.

 

 

If a “Request timed out” message appears (or the command times out),

 

 

the devices cannot communicate. Trace the cabling. If needed,

 

 

reconnect the devices.

Loss of Sync (>100ms)
