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 SWR2311P, but since login session and ID assignments depend on
the connection timing, you should normally make the same settings for all VTY ports.
2.1.3 Access from an SSH client
You can use an SSH client on a computer to connect to the SSH server of the SWR2311P and control it. In order to make
settings using SSH, you must first set up a connection environment (IP network) and then make SSH server settings.
The IP address settings of the SWR2311P 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 following settings on the SWR2311P must be made beforehand when accessing from an SSH client.
• Generate a host key on the SSH server using the
ssh-server host key generate
command.
• Enable the SSH server functions using the
ssh-server
command.
• Register the user name and password using the
username
command.
The SSH server settings of the SWR2311P are as follows.
• Access to an SSH server can be controlled for each VLAN, and is set using the
ssh-server interface
command.
• Note that the following functions are not supported.
• SSH protocol version 1
• User authentication aside from password authentication (host response authentication, public key authentication, challenge-
response authentication, GSSAPI authentication)
• Port forwarding (X11/TCP forwarding)
• Gateway Ports (Port relay)
• Permitting blank passwords
A virtual communication port by which an SSH client connects is called a "virtual terminal (VTY: Virtual TYpewriter) port."
The maximum number of simultaneous SSH client connections depends on the number of VTY ports of the SWR2311P. The
VTY ports of the SWR2311P 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 SWR2311P, but since login session and ID assignments depend on
the connection timing, you should normally make the same settings for all VTY ports.
2.1.4 Console terminal/VTY settings
The SWR2311P lets you make the following settings for console terminals and VTY.
1.
Timeout duration interpreted as no operation
2.
Number of lines shown in one page of the terminal screen
Setting item
Content of setting
Timeout duration interpreted as no operation
Specifies the time after which the login session is forcibly
ended when there has been no key input from the terminal.
With the default setting, the session is forcibly disconnected
after ten minutes.
To make this setting, use the
exec-timeout
command of the
line mode; this takes effect from the next session.
Number of lines shown in one page of the terminal screen
Specifies the number of lines shown on one page of the
terminal screen.
This can be set as 0--512 lines/page, and the default setting is
24 lines/page.
When displaying in this state, 23 lines are displayed, then "---
More---" is displayed and the system waits for key input.
There are two types of this setting, and they are applied to the
system starting with the upper type.
1) unprivileged EXEC mode
terminal length
command
2) global configuration mode
service terminal-length
