, the redirection function is enabled on the Router. The Router
listens to the specified TCP port number and receives data flows from the terminals through
asynchronous serial interfaces. After receiving data packets, the Router encapsulates the
packets into Ethernet frames so that they can be transmitted over an Ethernet network. In
this way, the intelligent terminals can be managed by a remote operation terminal.
Pre-configuration Tasks
Before configuring the redirection function, complete the following tasks:
l
Starting the remote devices
l
Directly connecting the remote devices to the 8AS board of the router through asynchronous
serial cables and ensuring that the 8AS board has registered successfully and the
asynchronous serial interfaces are in Up state
Data Preparation
To configure the redirection function, you need the following data.
No.
