Changing the Host Values of a M3UA or SUA Association

This procedure is used to change the host values of a M3UA or SUA association, assigned to cards that are running the SS7IPGW or IPGWI applications, using the chg-assoc command. If you wish to change the attributes of M3UA associations assigned to cards that are running the IPSG application, perform the Changing the Host Values of an IPSG Association procedure.

These parameters of the chg-assoc command are used in this procedure:

:aname – The name assigned to the association, shown in the rtrv-assoc output.

:lhost – The host name for the local host, shown in the rtrv-ip-host output.

:lport – The SCTP port number for the local host.

:rhost – The host name for the remote host, rhost can be any string of characters starting with a letter and comprising these characters ['a'..'z', 'A'..'Z', '0'..'9', '-', '.']. Hostnames are not case-sensitive and can contain up to 60 characters. The default value of this optional parameter is empty (null string).

:rport – The SCTP port number for the remote host.

:link – The signaling link on the IPGWx card. The value for the link parameter for M3UA or SUA associations is A.

Note:

The port parameter can be used in place of the link parameter to specify the signaling link on the card.

:adapter – The adapter layer for this association, either m3ua or sua. The adapter parameter is optional. The default value for the adapter parameter in this procedure is m3ua.

:alhost – The alternate local host name, shown in the rtrv-ip-host output.

:open – The connection state for this association. Valid values are yes or no. When the open=yes parameter is specified, the connection manager opens the association if the association is operational. When the open=no parameter is specified, the connection manager will not open the association.

:uaps – The UA parameter set value being assigned to either an M3UA or SUA association.

At least one optional parameter is required.

The command input is limited to 150 characters, including the hostnames.

The maximum number SCTP association to application server assignments that can be hosted by an IPGWx card (referenced by the lhost parameter of the association) is 50. For example, the IPGWx card currently contains 38 SCTP association to application server assignments. The SCTP association to application server assignments could be one SCTP association assigned to 38 application servers, two SCTP associations assigned to 19 application servers, or any combination of SCTP associations assigned to application servers that add up to 38. The SCTP association to application server assignments can be verified with the rtrv-assoc:lhost=<local host name> and rtrv-as:aname=<association name> commands.

* The EAGLE can contain a maximum of 250 application servers.

The EAGLE can contain a maximum of 4000 connections.

The B Ethernet interface of the IP card can be used on the E5-ENET cards.

If the card’s application is either SS7IPGW or IPGWI, the signaling link being assigned to the association must be in service. This state is shown in the rept-stat-slk output with the entries IS-NR in the PST field and Avail in the SST field.

Uni-homed endpoints are associations configured with the lhost parameter only. The lhost parameter value represents an IP address that corresponds to either the A or B network interface of the IP card. Multi-homed endpoints are associations configured with both the lhost and alhost parameters. The lhost parameter value represents an IP address corresponding to one of the network interfaces (A or B) of the IP card while the alhost parameter value represents an IP address corresponding to the other network interface of the same IP card.

The alhost=none parameter removes the alternate local host from the specified association, which also removes the multi-homed endpoint capability.

Canceling the RTRV-ASSOC and RTRV-AS Commands

Because the rtrv-assoc and rtrv-as commands used in this procedure can output information for a long period of time, the rtrv-assoc and rtrv-as commands can be canceled and the output to the terminal stopped. There are three ways that the rtrv-assoc and rtrv-as commands can be canceled.

  • Press the F9 function key on the keyboard at the terminal where the rtrv-assoc or rtrv-as commands were entered.
  • Enter the canc-cmd without the trm parameter at the terminal where the rtrv-assoc or rtrv-as commands were entered.
  • Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-assoc or rtrv-as commands were entered, from another terminal other that the terminal where the rtrv-assoc or rtrv-as commands were entered. To enter the canc-cmd:trm=<xx> command, the terminal must allow Security Administration commands to be entered from it and the user must be allowed to enter Security Administration commands. The terminal’s permissions can be verified with the rtrv-secu-trm command. The user’s permissions can be verified with the rtrv-user or rtrv-secu-user commands.

For more information about the canc-cmd command, go to Commands User's Guide.

  1. Display the associations in the database using the rtrv-assoc command.
    This is an example of possible output.

    If the required IP link, one that contains the desired IP address, is not shown in the rtrv-ip-lnk output, add the IP link using the Configuring an IP Link procedure. After the IP link has been added, assign the IP address of the IP link to the IP host name using the Adding an IP Host procedure, then continue the procedure with 11.

    If the required IP link is shown in the rtrv-ip-lnk output, but the IP host is not shown in the rtrv-ip-host output in 5, assign the IP address of the IP link to the IP host name using the Adding an IP Host procedure, then continue the procedure with 11.

    If the required IP host was shown in 5, the required IP link is shown in the rtrv-ip-lnk output in this step. Perform 7 to verify the application running on the card whose IP address is assigned to the IP host.

    Note:

    Thertrv-ip-host output must contain a host name for the association’slhost parameter and a host name for the association’salhost parameter, if thealhost parameter will be specified for the association. The IP address of the IP link should be assigned to the host name, shown in thertrv-ip-host output, that will be used as the association’slhost parameter value. If thealhost parameter will be specified for the association, the IP address of the IP link must be assigned to the host name that will be used as thealhost parameter value. The IP links associated with the association’slhost andalhost values must be assigned to the same card.
  7. Display the application running on the IP card shown in 6 whose IP address is assigned to the IP host using the rept-stat-card command specifying the location of the IP card.
    For this example, enter this command.

    If the required IPGWx signaling is not shown in this step, perform the Adding an IPGWx Signaling Link to add the required IPGWx signaling link. After the signaling link has been added, continue the procedure with Oracle.

  12. Change the association using the chg-assoc command.

    For this example, enter this command.

    chg-assoc:aname=assoc2:lhost=m3ua1:alhost=m3ua2:rhost=”gw200.nc-Oracle.com”

    These are the rules that apply to the chg-assoc command.
    • If any optional parameters are not specified with the chg-assoc command, those values are not changed.
    • E5-ENET cards can use the B Ethernet interface.
    • The number of association – application server assignments on an IPGWx card cannot exceed 50.
    • The EAGLE can contain a maximum of 4000 connections.
    • The value of the lhost and rhost parameters is a text string of up to 60 characters, with the first character being a letter. The command input is limited to 150 characters, including the hostnames.
    • Specifying the lhost parameter only creates a uni-homed endpoint. The network portion of the endpoint's IP address must be the same as the network portion of the IP address assigned to either the A or B network interface of the IP card.
    • Specifying the lhost and alhost parameters creates a multi-homed endpoint. The network portion of the IP address associated with the lhost parameter must be the same as the network portion of the IP address assigned to one of the network interfaces (A or B) of the IP card, and the network portion of the IP address associated with the alhost parameter must be the same as the network portion of the IP address assigned to the other network interface on the IP card.
    • The alhost=none parameter removes the alternate local host from the specified association, which also removes the multi-homed endpoint capability.
    • If the uaps parameter is not specified with the chg-assoc command, and the adapter parameter value is being changed to either m3ua or sua, the uaps parameter value defaults to UA parameter set 10 (uaps=10).
    • The port parameter can be used in place of the link parameter to specify the signaling link assigned to the association.

    When this command has successfully completed, this message should appear.

    CHG-ASSOC: MASP A - COMPLTD;
    

    Note:

    If the value of theopen parameter was not changed in3, continue the procedure withOracle.
  13. Change the value of the open parameter to yes by specifying the chg-assoc command with the open=yes parameter.
    For this example, enter this command.

    chg-assoc:aname=assoc2:open=yes

    When this command has successfully completed, this message should appear.

  14. Verify the changes using the rtrv-assoc command specifying the association name specified in Oracle and 13.

    For this example, enter this command.

    rtrv-assoc:aname=assoc2

    This is an example of possible output.
