The Console port is also known as the auxiliary (AUX) port.
The Switch 4210 Family supports two types of CLI-driven user interfaces, AUX and
VTY.
■
AUX user interface : The view when you log in through the console or AUX
port.
■
Virtual type terminal (VTY) user interface : The view when you log in locally
through an Ethernet port or remotely over the network using Telnet or SSH.
The VTY port is the logical port associated with your management session.
User Interface Index Index numbers are used to distinguish between multiple users accessing the
switch for management at the same time. There are two types of user interface
indexes, absolute user interface index and relative user interface index.
1 The absolute user interface indexes are as follows:
■
The absolute AUX user interface is numbered 0.
■
VTY user interface indexes follow AUX user interface indexes. The first
absolute VTY user interface is numbered 1, the second is 2, and so on.
