Solution

Stats Network Command Useful - The easiest way to display the communication statistics is to issue the "stats network" command at the CLI.

Look for errors, frames, collisons and drops.

Ask customer to check their network switch - "supportshow" file for collisions and drops. FE or customer should trouble shoot ethernet cabling from library interface to patch panel to the switch.
