How to use the commands
The SWP2 lets you perform command operations in the following two ways.
Type of operation Method of operation Description
Operation via console
• Access from a console terminal
• Access from a TELNET client
• Access from a SSH client
Issue commands one by one to
interactively make settings or perform
operations.
Operation via a config file
• File transfer via TFTP
• File transfer via GUI operation
A file containing a set of necessary
commands (called a configuration or
"config" file) is used to specify multiple
settings, or to obtain multiple settings from
the SWP2, in a single operation.
This chapter explains how to use each method.
2.1 Operation via console
2.1.1 Access from a console terminal
Use an RJ-45/DB-9 console cable when making settings from a terminal that is connected to the CONSOLE port of SWP2.
If you are using a computer as a console terminal (serial terminal), you'll need a terminal program to control the computer's
serial (COM) port. Set the communication settings of the console terminal as follows.
Setting item Value
Baud rate 9600bps
Data 8-bit
Parity none
Stop bit 1-bit
Flow control Xon/Xoff
For settings related to the console terminal, use the line con command to move to line mode.
2.1.2 Access from a TELNET client
You can use a TELNET client on a computer to connect to the TELNET server of the SWP2 and control it. In order to make
settings using TELNET, you must first set up a connection environment (IP network) and then make TELNET server settings.
The IP address settings of the SWP2 are as follows.
• The default IPv4 address setting is ip address dhcp for VLAN #1.
• To change the IPv4 address, use the ip address command.
The TELNET server settings of the SWP2 are as follows.
• With the default settings of the TELNET server function, it runs on the default port (TCP port 23) and allows access only
from VLAN #1 (vlan0.1).
• To change the reception port number, use the telnet-server command.
• Access to the TELNET server can be controlled in VLAN units, and can be specified by the telnet-server interface
command.
A virtual communication port by which a TELNET client connects is called a "virtual terminal (VTY: Virtual TYpewriter)
port." The maximum number of simultaneous TELNET client connections depends on the number of VTY ports of the SWP2.
The VTY ports of the SWP2 are as follows.
• With the default VTY port settings, eight VTY ports (ID: 0--7) can be used.
• To check the number of VTY ports, use the show running-config | include line vty command.
• To change the number of VTY ports, use the line vty command. (maximum 8 (ID: 0--7))
To make VTY port settings, use the line vty command to specify the target VTY port, and then move to line mode. ID
management for virtual terminal ports is handled within the SWP2, but since login session and ID assignments depend on the
connection timing, you should normally make the same settings for all VTY ports.
