You can log into an S7500 series Ethernet
switch in one of the following ways:
l
Logging in locally through the Console port
l
Telneting locally or remotely to an Ethernet
port
l
Telneting to the Console port using a modem
l
Logging in through NMS (network management
station)
S7500 series Ethernet switch supports two
types of user interfaces: AUX and VTY.

Each switch can accommodate up to five
VTY users.

The AUX port and
the Console port of a H3C series switch are the same port. You will be in the
AUX user interface if you log in through this port.
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
AUX user interface: 0
l
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:
l
AUX user interface: AUX 0
l
VTY user interfaces: VTY 0, VTY 1, VTY 2, and so
on.

Before executing
the auto-execute command command and save your configuration, make sure
you can log into the switch in other modes and cancel the configuration.

2 Logging in through the Console Port
To log in through the Console port is the most
common way to log into a switch. It is also the prerequisite to configure other
login methods. Normally, you can log into an S7500 series Ethernet switch
through its Console port.
To log into an Ethernet switch through its
Console port, the communication configuration of the user terminal must be in
accordance with that of the Console port.
Table 2-1
lists the default settings of a Console port.

After logging into a switch, you can
perform configuration for AUX users. Refer to section 2.3
“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 setting the connection to the Console
port
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) and perform the configuration shown in Figure 2-2 through Figure
2-4 for the connection to be created. Normally, the parameters of a terminal
are configured as those listed in Table 2-1. And
the type of the terminal is set to VT100.
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.
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 type the ? character. The commands available on a switch
are described in the command manuals.
