Protocol
Displays the active Link Layer protocol. This field displays PPP (Point to Point),
Frame Relay, or Other.

or None. None (the default value) is displayed when the line coding being used
on the interface is B8ZS.

2. Use the Protocol: field to select PPP, Frame Relay, or None. LEX (LAN
Extender) may also appear in the Protocol menu, but it is not applicable to a
DELHW-UA device.
NOTE
Data compression is not supported by the DELHW-UA at this time; therefore,
compression will always be de-activated or “Off”.
