5.1 Probing a Specific LAN Port

You can use the 'ethtool -p' command to locate a specific LAN port. For example, to blink the
Speed LED on LAN port 3 (e.g. device eth0_3) for 5 seconds:
- #ethtool -p eth0_3 5
With this command, users shall be able to find out the mapping between the physical LAN
port and the Ethernet device name, e.g. LAN port 3 <-> eth0_3.
