LOGGING INTO AN ETHERNET SWITCH
Logging into an
Ethernet Switch
You can log into an S4200-G series Ethernet switch in one of the following ways:
■ Logging in locally through the Console port
■ Telneting locally or remotely to an Ethernet port
■ Telneting to the Console port using a modem
■ Logging into the Web-based network management system
■ Logging in through NMS (network management system)
Introduction to the
User Interface
Supported User
Interfaces
S4200-G series Ethernet switch supports two types of user interfaces: AUX and VTY.
As the AUX port and the Console port of a S4200G series switch are the same one,
you will be in the AUX user interface if you log in through this port.
User Interface Number Two kinds of user interface index exist: absolute user interface index and relative user
interface index.
1 The absolute user interface indexes are as follows:
■ AUX user interface: 0
■ VTY user interfaces: Numbered after AUX user interfaces and increases in the step
of 1
2 A relative user interface index can be obtained by appending a number to the
identifier of a user interface type. It is generated by user interface type. The relative
user interface indexes are as follows:
■ AUX user interface: AUX 0
■ VTY user interfaces: VTY 0, VTY 1, VTY 2, and so on.
