FEATURE CONFIGURATION
The ES8508 provides both in-band and out-band configuration methods:
Out-band management means that you configure the ES8508 using the
RS-232 console cable and the Command Line Interface (CLI) to access the
ES8508 without attaching an admin PC to the network. You can also use
out-bound management, if you lost the network connection to the ES8508.
