70CHAPTER 4: TERMINAL SERVICE

By default, no X.25 PAD remote user is configured at the Server side.

For details of the Command, refer to the relevant sections on Security

Configuration Commands in Command Reference (V1.6).

Start AAA authentication of X.25 remote users

After the configuration of X.25 PAD remote users, AAA authentication is started at the Server side for the purpose of identity authentication on receipt of a remote PAD request.

This command is not mandatory, but if required, it must be used together with the user command.

Please implement the following configuration under the system view at the Server side.

Table 52 Enable AAA authentication for X.25 remote PAD users

Operation	Command
Enable AAA authentication of X.25 remote	login pad
user
Disable AAA authentication of X.25 remote	undo login pad
user

Configure user name and password	local-user username password
	password

By default, there is no AAA authentication for X.25 remote PAD users.

Establish an X.25 PAD call

In the routers interconnected through X.25 network, the following commands are used to place a PAD call to remote terminals. If both terminals support X.25 PAD, the call will be authenticated at the Server side. (If user authentication is not set, this step can be skipped.). If the authentication succeeds, the Client side can access the Server side and configure the Server side. After successful access of the remote terminals, users can log out and disconnect the X.25 PAD connection.

Please implement the following configuration under the system view at the Client side.

Table 53 Establish a X.25 PAD call

Operation	Command
Establish a X.25 PAD call	pad x.121-address
Exit X.25 PAD login	exit

If a call successfully logs on, the user can, at the Client side, access the Server.

Pad command can be nested with itself or with the telnet command, that is, the user can place an X.25 PAD call on a router and access another router, from which they do the same and access a third router. Or, the user first Telnets to a router from which they can place X.25 calls and access a third router. Or, users can place X.25 calls, access a router and then telnet to another router, and so on. It is recommended to limit the nesting to three times to ensure normal transmission.
