The X.25 SVC Address Key Paths screen (#162) in Figure 7-8 "X.25 SVC Address Key Paths" is displayed when you press the [Go To SVCPATH] function key at the General X.25 Configuration screen (Figure 7-5 "General X.25 Protocol Screen"). It is also displayed when you type the path name:

@NETXPORT.NI.NIname.PROTOCOL.X25.SVCPATH

in the Command window of any screen and press the [Enter] key, where NIname is a configured X.25 NI.

[X.25 SVC Address Key Paths]

The X.25 address key is a label which associates an X.25 address with an IP address from the network directory. This provides you the address of the remote host and the values of the connection parameters you selected to use when communicating with that host. Every remote address defined in the path table must be assigned a default facilities set. You may configure up to 2048 SVC address keys under an X.25 NI, and if configuring multiple X.25 NI's, no address key can be used more than once per system.

The default facilities set must be one of the defined facility sets in the X.25 User Facility Set screen (NETXPORT.NI.NIname.PROTOCOL.X25.FACSET).

POOL is the X.25 address key reserved for calls to and from nodes whose addresses are not defined in this X.25 SVC Address Key Path screen. When a POOL X.25 address key is used, any system, even one that is not identified in this screen, can access this node. HP recommends that you use the name portion of the formal node name (name.domain.organization) as the X.25 address key. You can have a maximum of 2048 address keys in the SVC path tables and 128 address keys in the PVC path tables. If configuring multiple X.25 NI's, no address key can be used more than once per system. POOL can also be used with level 3 programmatic access when specifying an X.25 address directly in a NetIPC call (for example, the IPCDEST call)

NOTE: For DDN networks, the X.25 address is derived from the remote IP address and you are not required to know the remote X.25 address. Mapping is only required between the X.25 address key and the facility set.

Fields

X.25 address key

(Required.) The X.25 address key identifies a remote node to which your node can establish a connection. The address key can have up to eight alphanumeric characters, the first of which must be alphabetic.

X.25 address

This is the X.25 address of the remote node for X.25 public data networks (PDN) or a private X.25 network. The X.25 address can have up to 15 digits. The X.25 address will not be used if you configure a POOL address key, or if you are configuring a link for a DDN network.

Default: None.

Default facilities set name

The name of one of the facility sets you defined at the User Facility Set screen. This set of facilities is associated with the connections you have previously defined. This field is required if you define an address key.

Default: None

Security

The level of security you wish to assign to this particular entry. The possible values are as follows:

  • IN is the level of security you assign to accept only incoming calls from the specified remote address.

  • OU is the level of security you assign to accept only outgoing calls to the specified remote address. All incoming calls are rejected.

  • IO is the level of security you assign to accept both incoming and outgoing calls.

  • LK is the level of security you assign to lock this entry so that no calls, incoming or outgoing, are accepted. LK is useful if you are using POOL to accept calls from all nodes, but you want to exclude a few nodes from accessing this node. Enter the nodes you want to restrict in this screen and specify LK as the security.

This field is required if you defined an address key.

Default: IO
