PAD configuration command directory

This chapter describes the command used to configure interoior grouping assembling/disassembling, PAD is used to connect the remote device of X.25 protocol.

Use the following command to configure interoior PAD:

Use pad command to access and use pad standard interface. Enters pad mode after execution of pad command, the router prompts change as signal of greater, you can configure X.3 PAD parameter under this mode.

Note: About configuration tasks and examples, please refer to chapter “configure the PAD of X.25”.

pad

TO log on to PAD, use EXEC command of pad user:

pad svc x121-address [profile-number [r|w]]

pad pvc interface-number pvc-number [profile-number [r|w]]

parameter:

svc

Use svc to call

pvc

Use pvc to perform pad operation

x121-address

Designates X.121 address of X25 host.

Interface-number

Designate the interface of pvc pad.

Pvc-number

Pvc number used by pad.

profile-number

Use X3 parameter provided by this profile to perform responsion request

r

X3 parameter provided by profile is read-only.

w

X3 parameter provided by profile is rewritable

Command mode:

User mode or supervisor mode

Explanation:

You can simultaneously allow many PAD connections to open and switch between them, you can also quit connection and returns to user mode prompt at any locations.

In order to quit the session, simply stop the connection with remote system, then input command exit to stop active session.

PAD mode is tagged with greater mark router prompt, after enter this mode, you can use standard PAD user interface (except transferred meaning sequence). You can use X.3 parameter to configure PAD device or access X.25 from this interface.

In PAD mode, you can use standard or extension command to configure PAD command signal. For example, you can input command clr or clear to clear virtual calls. The command designated with standard command grammar is only the brief version of extension grammar version.

Use pad operation of PVC to send reset request packet and enable a session, send or receive reset packet to stop a session.

1)   600 is the first to rely on value of PAD type;

2)   275 is from PAD; 1200 to PAD.

Default:

For PAD outgoing connection, default value of X.3 parameter is as follows:

2 : 1,  3 : 2,  4 : 1 ,  7 : 4 , 16 : 127,  17 : 21,  18 : 19

Default value of all other parameters are 0, but can be changed with command “set”.

For incoming PAD connection, the soft sending X.29 set parameter grouping only configures the following parameters:

 2 : 0 , 4 : 1 , 7 : 21 , 15 : 0

example:

The following example enables a PAD session:

Router A# pad 123456789

Trying 123456789Open

Router B>

Relevant command:

x29 profile

show x29
