Description
Entering the protocol command without arguments displays the
current Level 2 and Level 3 protocol selection.
This command lets you specify a level 2 or level 3 protocol for analysis

command.
The function of the protocol command is also implemented in the form
of an option to the run and runc commands. When you use run or runc
