SS7 Routing Domain Configuration Mode Commands


SS7 Routing Domain Configuration Mode Commands
 
 
The SS7 Routing Domain configuration mode is used to configure Signaling System 7 (SS7) parameters. For convenience in configuration management, all SS7 parameters have been collected into a proprietary grouping called an SS7 routing domains.
 
Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
 
asp
This command creates or removes an M3UA Application Server Process (ASP) instance and enters the ASP configuration mode. See the SGSN ASP Configuration Mode chapter in the Command Line Interface Reference for command details.
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
asp instance asp_inst
no asp instance asp_inst
default asp instance asp_inst end-point port
no
Deletes the ASP instance for the SS7 routing domain configuration.

instance asp_inst
Identifies a specific ASP configuration. Up to four ASP instances can be configured for a single SS7 routing domain.
asp_inst : Must be an integer from 1 through 4.
Usage
Use this command to create an ASP instance or enter the ASP configuration mode.

end
Exits the current configuration mode and returns to the Exec mode.
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
exit
Usage
Return to the Exec mode from any configuration mode.
 
exit
Exits the current configuration mode and returns to the context configuration mode.

inbound-asp-identifier validate
This command enables validation of ASP identifiers inbound to the SGSN via routes defined with this SS7 routing domain.
Important: This command is only available in releases 8.1 and higher.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
 
inbound-asp-identifier validate
[ default | no ] inbound-asp-identifier validate
default
Validates the inbound ASP Id.
no
Disables validation of the inbound ASP Id.
Usage
The standard is to validate the ASP Id. However, in some circumstances it is necessary to skip such validation. For example, if the same ASP Id is assigned to more than one RNC (peer-server).
Example
Use the following command to skip validation of inbound ASP Ids:
no inbound-asp-identifier validate
Use either of the following commands to enable validation if it has been disabled:
default inbound-asp-identifier validate
inbound-asp-identifier validate
 
linkset
This command creates an instance of an MTP3 linkset and enters the linkset configuration mode. See the Linkset Configuration Mode chapter in Command Line Interface Reference for the commands to configure the linkset.
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
linkset id id
no linkset id id
no
Removes the identified linkset definition from the system configuration.
id
This value uniquely identifies a linkset for the specific SS7 routing domain.
id : Must be an integer of 1 to 49.
Usage
This command creates instances of linkset configurations and provides access to the linkset configuration mode.
Example
Use the following command to create the 12th linkset:
linkset id 12
 
MTU-size
This command has been deprecated.
 
peer-server
This command creates a peer-server instance to setup a SIGTRAN peer for sending and receiving M3UA traffic. Completing the command automatically enters the peer- server configuration mode. To define 1 or more (up to 145) peer servers, use the commands documented in the Peer-Server Configuration Mode chapter in this reference.
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
peer-server id srvr_id
no peer-server id srvr_id
no
Removes the identified peer-server definition from the system configuration.
srvr_id
srvr_id uniquely identifies a peer-server. The id must be an integer from 1 to 49.
Usage
Use the following command to create a definition for peer-server 2 and enter the configuration mode to configure the communication parameters for peer-server 12.
Example
peer-server id 12
 
route
This command configures SS7 routes for the current SS7 routing domain.
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
route destination-point-code dp_code { linkset id id [ priority pri_value ] | peer-server-id srvr_id }
no route destination-point-code dp_code { linkset id id | peer-server-id srvr_id }
no
Removes the SS7 route from the current SS7 routing domain configuration.
destination-point-code dp_code
Specifies the SS7 destination point code for this route.
Reminder: the point-code structure must match the variant defined for the SS7 routing domain when the SS7RD was configured in the global configuration mode.
linkset id id
This keyword identifies a linkset instance, created and configured with the linkset command.
This keyword identifies a linkset instance, created and configured with the linkset command.
id : Must be an integer from 1 to 49.
peer-server-id srvr_id
This keyword identifies a peer-server configuration instance, created and configured with the peer-server command.
srvr_id must be an integer from 1 to 49.
Usage
This command associates the previoiusly configured linksets and peer servers and the destination point codes with a specified SS7 route.
Example
Define a route setting an ITU-type destination point-code address for the linkset Id 12:
route destination-point-code 6.211.6 linkset id 12
 
routing-context
Identifies the routing context for this SS7 routing domain.
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
routing-context value
default routing-context
default
Resets the local routing context value to the index (instance ID) for this SS7 routing domain.
value
An integer that uniquely identifies the routing context for this SS7 routing domain.
value : Must be integers from 1 to 65535 (for releases 8.0) or 1 to 4294967295 (for releases 8.1 and higher) .
Usage
Use this command to set the routing context IDs for a specific SS7 routing domain configuration.
Example
routing-context 2355
 
ssf
This command sets the network indicator in the subservice field for SS7 message signal units (MSUs).
Product
SGSN, HNB-GW
Privilege
Security Administrator, Administrator
Syntax
 
ssf ( international | national | reserved | spare }
international
The network indicator identifies the message as international with a point code structure that does not match the national point code structure,
national
The network indicator identifies the messages as having a national point code structure.
reserved
Provides an alternate network indicator for national messages.
spare
Provides an alternate network indicator for international messages.
Usage
In SS7 signaling, the Message Transfer Part (MTP) Level 2 message signal units (MSUs) contain a service information octet (SIO). The SIO field in an MSU contains a 4-bit subservice field (SSF) followed by a 4-bit service indicator. The indicator carried in the message’s routing information typically identifies the structure of the point code as a message from within a nation or as a message coming from outside the nation - international. As well, the 4-bit SSF determines the point code structure of the messages transmitted from the SGSN.
Example
For messages being transmitted within a country, set the indicator to national with the following command.
ssf national
