This chapter describes the parameters for configuring serial lines on your bridge/router for communication with an X.25 public or private data network. Table 139 lists the X25 Service parameters and commands.
Syntax
SHow [!<port>| !*] -X25 CONFiguration
No default
The CONFiguration parameter displays the values of the X25 Service parameters for all the serial ports. If you want to display the configuration for a specific port, specify the port number.
Syntax
SETDefault !<port> -X25 CONTrol = [ExtendedPacketSeq| NoExtendedPacketSeq]
SHow [!<port>|!*] -X25 CONTrol
SHowDefault [!<port>|!*] -X25 CONTrol
NoExtendedPacketSeq
The CONTrol parameter configures extended packed sequence numbering for a specified port.
Values
|
ExtendedPacketSeq |
Indicates that packet sequencing is performed modulo 128. |
|
NoExtendedPacketSeq |
Indicates that packet sequencing is performed modulo 8. |
Syntax
SETDefault !<port> -X25 IncomingSVCs = NONE | <1-4095> {,<1-4095>}
SHow [!<port> | !*] -X25 IncomingSVCs
SHowDefault [!<port> | !*] -X25 IncomingSVCs
NONE
The IncomingSVCs parameter specifies the circuits or logical channel numbers (LCNs) on each port allocated exclusively for incoming calls. The X.25 standard specifies a range of 1 through 4095 LCNs, which can be used for permanent incoming, outgoing, or two-way (both incoming and outgoing) calls. The IncomingSVCs parameter specifies the number of LCNs allocated exclusively for incoming calls.
Values
Syntax
ADD -X25 NbrPROFile <dte_addr(1..14 digits)> <profile id>
DELete -X25 NbrPROFile <dte_addr(1..14 digits)> <profile id>
SHow -X25 NbrPROFile
No default
The NbrPROFile parameter configures a profile ID for each neighboring data terminal equipment (DTE). This profile ID overrides the X.25 profile ID configured for a specified port when establishing a call to or from a DTE. If the profile ID is not assigned to a neighboring DTE, the X25PROFileid parameter value is used. The DELete command removes the association between the X.25 DTE address and the X.25 DTE profile.
For more information on configuring a profile ID, see "X25PROFileid" later in this chapter.
Syntax
SETDefault !<port> -X25 OutgoingSVCs = NONE | <1-4095> {,<1-4095>}
SHow [!<port> | !*] -X25 OutgoingSVCs
SHowDefault [!<port> | !*] -X25 OutgoingSVCs
NONE
The OutgoingSVCs parameter specifies the number of LCNs allocated exclusively for outgoing calls. The X.25 standard specifies a range from 1 through 4095 LCNs to be distributed for permanent incoming, outgoing, or two-way (both incoming and outgoing) traffic. You can distribute the LCNs according to the requirements of your installation.
Values
Syntax
SETDefault !<port> -X25 PDNetworkType = PRIVATE | TELENET | TYMNET | PSS | DDN | BFE | NET2 | DATEX | TRANSPAC | LAPOSTE
SHow [!<port> | !*] -X25 PDNetworkType
SHowDefault [!<port> | !*] -X25 PDNetworkType
PRIVATE
The PDNetworkType parameter configures a port for communication with a particular type of public data network. For example, if you subscribe to the Telenet public data network (PDN), you need to set this parameter to TELENET.
Syntax
ADD !<port> -X25 PVC <lcn1> [,lcn2] <destination dte address> <protocol ID> [<user profID>]
DELete -X25 PVC <lcn1>, <lcn2>
SHow -X25 PVC
No default
The PVC parameter configures a permanent virtual circuit on the specified logical channel numbers (LCNs) to and from the specified DTE address.
Values
Syntax
SHow [!<port> | !*] -X25 STATUS
No default
The STATUS parameter provides information about the status of the X.25 line, including the virtual circuit number, the virtual circuit state, the packet size, the window size used by the virtual circuit, the user and DTE profile IDs, compression type, and the DTE address to or from which the virtual circuit was originated.
Syntax
SET !<port> -X25 Trace = ([Data | NoData], [Control | NoControl])
SETDefault !<port> -X25 Trace = ([Data | NoData], [Control | NoControl])
SHow [!<port> | !*] -X25 Trace
SHowDefault [!<port> | !*] -X25 Trace
NoData, NoControl
The Trace parameter displays information for the specified X.25 port at the network layer (level 3) for debugging purposes. This parameter can be set to display both packet contents and header contents or header only.
Values
Syntax
SETDefault !<port> -X25 TwowaySVCs = NONE | <1-4095> {,<1-4095>}
SHow [!<port> | !*] -X25 TwowaySVCs
SHowDefault [!<port> | !*] -X25 TwowaySVCs
1, 4095
The TwowaySVCs parameter specifies the number of circuits to be used for two-way calls. The X.25 standard specifies a range of from 1 through 4,095 logical channel numbers (LCNs) to be used for permanent incoming, outgoing, or two-way (both incoming and outgoing) traffic. TwowaySVCs specifies the number of LCNs allocated exclusively for two-way (both outgoing and incoming) traffic. The default assigns all switched virtual circuits (SVCs) with LCN numbers from 1 through 4,095 as two-way SVCs.
Values
|
NONE |
Specifies that no circuits are used for two-way calls. |
|
<min>, <max> |
Specifies one or more numbers between 1 and 4095 to indicate the circuits to be used exclusively for two-way calls. |
Syntax
SETDefault !<port> -X25 X25Address = NONE | <0-99999999999999>(1-15 digits)>
SHow [!<port> | !*] -X25 X25Address
SHowDefault [!<port> | !*] -X25 X25Address
NONE
The X25Address parameter assigns the local DTE address for each port used for X.25 routing. A DTE address must be configured for each port used for X25 Service in all data networks except a PDN. To remove an address, use the NONE value.
Do not specify this parameter for a virtual port; specify it for a nonvirtual port only.
Syntax
SETDefault !<port> -X25 X25PROFileid = <profile ID (0-255)>
SHow [!<port> | !*] -X25 X25PROFileid
SHowDefault [!<port> | !*] -X25 X25PROFileid
0
The X25PROFileid parameter creates an X.25 profile. When you specify a profile ID, X.25 uses the specified DTE profile to establish a call request for that port. A profile ID of 0 means the default DTE profile will be used.
Syntax
FLush [!<port>] -X25 X25STATistics
SHow [!<port> | !*] -X25 X25STATistics
SHowDefault [!<port> | !*] -X25 X25STATistics
No default
The X25STATistics parameter displays the statistics for the specified port. If no port is specified, statistics for all ports are displayed.
The FLush command clears the X.25 statistics.
