Asynchronous Rtc Terminal Access Configuration Example - 3Com MSR 50 Series Configuration Manual

n
Asynchronous RTC
Terminal Access
Configuration Example
To do...
Configure the password
for the VTY
authentication
Configure the RTC
server to perform VTY
switching by priority
(the lower the VTY
number, the higher the
priority)
Update the
configuration
The port number specified for the VTY application on the RTC client must be
■
the same as the listening port number specified on the RTC server.
The terminal-number argument of the command vty rtc-server remote
■
configured on the RTC server must be the same as the terminal-number
argument of the command rta terminal configured on the RTC client;
otherwise, no TCP connection can be established
Each terminal of the RTC server corresponds to a different RTC client.
■
If not configured with the bind vpn-instance command, the RTC server can
■
accept connection requests from any VPNs.
The TCP parameters must be configured before a TCP connection is
■
established. If you configure the parameters after a TCP connection is
established, the TCP connection must be reestablished for the parameters to
take effect. Pressing the reset hotkey on the terminal can reestablish the TCP
connection.
The receive buffer size must be configured before a terminal template is
■
applied. If you configure the receive buffer size after a terminal template is
applied, you need to remove the application of the terminal template and
apply the terminal template again for the receive buffer size to take effect.
Network requirements
Two routers, one serving as the RTC client and the other the RTC server, are
connected to the central terminal device and the remote terminal device
respectively.
The RTC listening port of the RTC server is 9000.
■
The central terminal device is connected to the asynchronous serial interface
■
Async1/0 on the RTC client. The remote terminal device is connected to the
asynchronous serial interface Async1/0 on the RTC server.
The RTC client and the RTC server have the same terminal number of 1.
■
RTC Terminal Access Configuration
Use the command...
vty vty-number password
{ simple | cipher } string
vty-switch priority
update changed-config
Remarks
Optional
Not configured by default
Optional
By default, the VTY switching is
performed not by priority.
