Logging
In to an Ethernet Switch

Introduction
to the User Interface
You can log in to an S5600 Ethernet switch
in one of the following ways:
l
Logging in locally through the console port
l
Logging in locally or remotely through an
Ethernet port by means of Telnet or SSH
l
Telnetting to the console port using a modem
l
Logging in to the Web-based network management
system
l
Logging in through NMS (network management station)
The auxiliary (AUX)
port and the console port of an H3C low-end and mid-range Ethernet switch are
the same port (referred to as console port in the following part). You will be
in the AUX user interface if you log in through this port.
S5600 series Ethernet switches support two
types of user interfaces: AUX and VTY.
l
AUX user interface: A view when you log in through
the AUX port. AUX port is a line device port.
l
Virtual type terminal (VTY) user interface: A
view when you log in through VTY. VTY port is a logical terminal line used when
you access the device by means of Telnet or SSH.

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:
l
The absolute AUX user interfaces are numbered 0
through 7.
l
VTY user interface indexes follow AUX user
interface indexes. The first absolute VTY user interface is numbered 8, the
second is 9, and so on.
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:
l
AUX user interfaces are numbered from AUX0 to AUX7.
l
VTY user interfaces are numbered VTY0, VTY1, and
so on.
S5600 series
Ethernet switches support Fabric. A Fabric can contain up to eight devices.
Accordingly, the AUX user interfaces in a Fabric can be numbered from AUX0 to
AUX7, through which all the console ports of the units in a Fabric can be
identified. Refer to the IRF Fabric part for information about Fabric.

To log in through the console port is the
most common way to log in to a switch. It is also the prerequisite to configure
other login methods. By default, you can locally log in to an S5600 Ethernet
switch through its console port only.
Table 2-1 lists the
default settings of a console port.

To log in to a switch through the console
port, make sure the settings of both the console port and the user terminal are
the same.
After logging in to a switch, you can
perform configuration for AUX users. Refer to Console Port Login Configuration for more.
Following are the procedures to connect to
a switch through the console port.
1)
Connect the serial port of your PC/terminal to
the console port of the switch, as shown in Figure 2-1.
Figure 2-1 Diagram for connecting to the console
port of a switch
2)
If you use a PC to connect to the console port,
launch a terminal emulation utility (such as Terminal in Windows 3.X or HyperTerminal
in Windows 9X/Windows 2000/Windows XP. The following assumes that you are
running Windows XP) and perform the configuration shown in Figure 2-2 through Figure 2-4 for the
connection to be created. Normally, both sides (that is, the serial port of the
PC and the console port of the switch) are configured as those listed in Table 2-1.
Figure 2-2 Create a connection
Figure 2-3 Specify the port used to
establish the connection
Figure 2-4 Set port parameters
3)
Turn on the switch. You will be prompted to
press the Enter key if the switch successfully completes POST (power-on self
test). The prompt (such as <H3C>) appears after you press the Enter key,
as shown in Figure 2-5.
Figure 2-5 HyperTerminal CLI
4)
You can then configure the switch or check the
information about the switch by executing the corresponding commands. You can
also acquire help by typing the ? character. Refer to related parts in this
manual for information about the commands used for configuring the switch.

port. To configure a console port, you are recommended to log in to the switch
in other ways. To log in to a switch through its console port after you modify
the console port settings, you need to modify the corresponding settings of the
terminal emulation utility running on your PC accordingly in the dialog box
shown in Figure 2-4.
