AlliedWare Plus™ Command Modes
The AlliedWare Plus™ command line interface consists of a series of
modes that are arranged in the hierarchy shown in Figure 1.
Figure 1. Command Modes
The modes have different commands and support different management
functions. To perform a management function, you first have to move to
the mode that has the appropriate commands. For instance, to add new
VLANs, you must move to the VLAN Configuration mode because the
VLAN command is effective only in that mode.
