Huawei AR2200 Series - Checking the Configuration

The redirection function is associated with a VPN instance.
By default, the redirection function is not associated with any VPN instance, and all users on
public and private networks can use the redirection function to log in to remote devices.
Step 9 (Optional) Run:
redirect listen-port port-num
The port number is set for the redirection function.
The default port number is 2000 plus tty-number. When the default port number is used by
another service, perform this step to set a new port number.
NOTE
l The terminal attributes of a TTY user interface must be the same as the physical attributes of the terminal
connected to the corresponding asynchronous serial interface. For details on how to configure terminal
attributes of a TTY user interface, see 4.4.3 Setting Terminal Attributes of TTY User Interface.
l If the modem function is enabled on a TTY user interface, the redirection function does not take effect.
----End
Follow-up Procedure
Run the telnet host-name port-number command to log in to a remote device. In the command,
host-name is the IP address or host name of the router with the redirection function enabled, and
port-number is the default port number or the port number configured by running the redirect
listen-port command.

After completing the configuration of the redirection function, check the TCP connection status
to verify the configuration.
Prerequisite
All configurations of the redirection function are complete.
