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
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
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.
