Adding an IPSG M2PA Association

This procedure is used to configure IPSG M2PA associations using the ent-assoc command. The combination of a local host, local SCTP port, remote host and remote SCTP port defines an association. IPSG M2PA associations are assigned to E5-ENET cards running the IPSG application (IPSG cards).

The ent-assoc command uses these parameters to add an IPSG M2PA association to the database.

:aname – The name assigned to the association. Valid association names can contain up to 15 alphanumeric characters where the first character is a letter and the remaining characters are alphanumeric characters. The aname parameter value is not case-sensitive.

:lhost – Local Hostname. The logical name assigned to the local host device.

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

:rhost – Remote Hostname. The logical name assigned to the remote host device.

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

:adapter – The adapter layer for this association, m2pa. The adapter parameter is optional. The default value for the adapter parameter is m2pa.

:alhost – The alternate local host name.

:m2patset – The M2PA timer set assigned to the association. The m2patset parameter can be specified only with the adapter=m2pa parameter. If the adapter=m2pa parameter is specified, and the m2patset parameter is not specified with the ent-assoc command, the default value for the m2patset parameter (1 - M2PA timer set 1) is assigned to the association.

Associations contain fields whose values are not assigned using the ent-assoc command. When an association is added to the database, these fields receive their default values. If a different value is desired, the chg-assoc command must be used. To change these values perform the Changing the Attributes of an IPSG Association procedure.

These fields and their default values are shown in Table 6-6.

Table 6-6 IPSG M2PA Association Fields and Default Values

open=no

rmax=800

cwmin=3000

alw=no

uaps=10

istrms=2

rmode=lin

rtimes=10

ostrms=2

rmin=120

ver=rfc bufsize=200 rtxthr=0 rhostval=relaxed

The link parameter cannot be specified for an IPSG M2PA association.

An IPSG M2PA association can contain an alternate remote host. The alternate remote host is provisioned with the rhost and rhostype=alternate parameters of the chg-assoc command. A primary remote host can be provisioned on this procedure by specifying the rhost parameter with the ent-assoc command. To provision an alternate remote host for an IPSG M2PA association, perform Changing the Attributes of an IPSG Association.

The size of the buffers on the IPSG cards is 3200 KB. The size of the buffers assigned to each association that is assigned to the IPSG card cannot exceed the maximum buffer size for the IPSG card. When a new association is added, the default buffer size for the association is assigned to the association. If adding the new association causes the total buffer size for all the associations on the IPSG card to exceed the maximum buffer size for that IPSG card, the ent-assoc command will be rejected. If the you wish to add the association and the maximum buffer size for the IPSG card will be exceeded, the buffer size of the other associations assigned to the IPSG card must be decreased by performing the Changing the Buffer Size of an IPSG Association procedure. The available size of the buffers on the IPSG card can be verified by entering this command.

rtrv-assoc:lhost=<local host name assigned to the association>

The alhost parameter can also be used with the rtrv-assoc command to display the available size of the buffers on the IPSG card.

The aname parameter can be used with the rtrv-assoc command to display the available size of the buffers on the IPSG card and the size of the buffer assigned to the association.

The value of the lhost, rhost, or alhost parameters is a text string of up to 60 characters, with the first character being a letter. The command line on the terminal can contain up to 150 characters. If the host names are too long to fit on the ent-assoc command line, perform the chg-assoc command with the parameters and values necessary to complete the entry of the M2PA association.

The EAGLE can contain a maximum of 4000 connections (association to application server assignments).

A maximum of 32 IPSG M2PA associations can be assigned to an IPSG card.

The B Ethernet interface of the IPSG card can be used.

To activate the association after the association is assigned to a signaling link, the association must contain values for the lhost, lport, rhost, rport parameters.

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 IPSG 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 IPSG card.

An alternate remote host can be configured for multi-homed associations using the rhost and rhosttype parameters of the chg-assoc command. The rhost parameter value with the rhostype=primary parameter represents an IP address that corresponds to one of the network interfaces at the remote end while the rhost parameter value with the rhostype=alternate parameter represents an IP address that corresponds to the other network interface at the remote end.

Canceling the RTRV-ASSOC Command

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

  • Press the F9 function key on the keyboard at the terminal where the rtrv-assoc command was entered.
  • Enter the canc-cmd without the trm parameter at the terminal where the rtrv-assoc command was entered.
  • Enter the canc-cmd:trm=<xx>, where <xx> is the terminal where the rtrv-assoc command was entered, from another terminal other that the terminal where the rtrv-assoc command was 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.

    Perform one of these actions.
    • If the desired IP link (shown by the entries in the CARD LOC and IPLNK PORT columns for an association whose ADAPTER value is M2PA) is shown in the rtrv-assoc output, continue the procedure with 2.
    • If the desired IP link is not shown in the rtrv-assoc output, continue the procedure with 4.
  2. Display the card that the new M2PA association will be assigned to by entering the rtrv-card command with the card location displayed in 1. For this example, enter this command.

    rtrv-card:loc=1203

    The following is an example of the possible output.

    If the value in the TYPE column is IPSG, continue the procedure with 3.

    If the value in the TYPE column is either IPLIM or IPLIMI, the host assigned to this card cannot be used in this procedure. If you wish to use this card to configure an M2PA association, perform the Adding an M2PA Association procedure.

    If you do not wish to use this card to configure an IPSG M2PA association, perform one of these actions.
    • Choose another card from the rtrv-assoc output in 1 and repeat this step.
    • Continue the procedure with 4 to choose another IPSG card and IP link for the new IPSG M2PA association.
  3. Display the associations assigned to the card that the new association will be assigned to by entering the rtrv-assoc command with the card location specified in 2. For this example, enter this command.

    rtrv-assoc:loc=1203

    The following is an example of the possible output.

    An IPSG card can contain a maximum of 32 IPSG M2PA or M3UA associations when running on the E5-ENET/E5--ENET-B card or DEIR card. An IPSG application running on the SLIC card can contain a maximum of 128 associations.. If 32 associations are displayed in the rtrv-assoc output, the new IPSG M2PA association cannot be added to this card. Choose another IPSG card and repeat this procedure from 1.

    If less than 32 associations are shown in the rtrv-assoc output, continue the procedure with 6.

  4. Display the IP links in the database by entering the rtrv-ip-lnk command. The following is an example of the possible output.

IP-LNK   table is (20 of 2048) 1% full.

    If the required IP link is not in the database, add the IP link using the Configuring an IP Link procedure.

  5. Verify that the local host name to be assigned to the association is in the database by using the rtrv-ip-host:display=all command. The following is an example of the possible output.

IP Host table is (11 of 4096) .26% full

    The IP address of the IP link should be assigned to the local host name that will be assigned to the association.

    The values of the lhost and alhost parameters must be in the LOCAL HOST column in the rtrv-ip-host output.

    If the required hostname is not in the database, add the IP host name using the Adding an IP Host procedure.

  6. Verify the values of the M2PA timer set you wish to assign to the association by entering the rtrv-m2pa-tset command with the ver=rfc parameter.

    When an IPSG M2PA association is provisioned in this procedure, the RFC M2PA version is assigned to the IPSG M2PA association by default.

    The M2PA version of the association determines the version of the M2PA timer set that is assigned to the association. For example, if M2PA timer set 3 is assigned to the IPSG M2PA association, and the association is an RFC IPSG M2PA association, the RFC version of M2PA timer set 3 is used with the association. If M2PA timer set 7 is assigned to the IPSG M2PA association, and the association is a Draft 6 IPSG M2PA association, the Draft 6 version of M2PA timer set 7 is used with the association.

    If you wish to assign the Draft 6 M2PA version to this association and use the Draft 6 M2PA timer sets, perform the Changing the Attributes of an IPSG Association procedure after this procedure is completed to change the M2PA version of this association.

    Note:

    If them2patset parameter will not be specified with theent-assoc command, theM2PA timer set 1 will be assigned to the association.

    To display the M2PA Draft 6 timer values, enter this command.

    rtrv-m2pa-tset:ver=d6

    This is an example of the possible output.

    If the M2PA timer set you wish to assign to the association does not contain the desired values, go to the Changing an M2PA Timer Set procedure and changed the desired timer values.

    Caution:

    Changing an M2PA timer set may affect the performance of any associations using the timer set being changed.
  7. Verify the available buffer size for the IPSG card that will contain the association being added in this procedure by entering the rtrv-assoc command with the local host name assigned to the association being added. For this example, enter this command.

    Note:

    If a new host was added in 5, continue the procedure with 8.

    rtrv-assoc:lhost="IPNODE2-1203"

    This is an example of the possible output.

    If adding the new association causes the total buffer size for all the associations on the IP card to exceed the maximum buffer size for that IP card, the ent-assoc command will be rejected.

    The default buffer value for an IPSG M2PA association is 200.

    If the you wish to add the association and the maximum buffer size for the IP card will be exceeded, the buffer size of the other associations assigned to the IP card must be decreased by performing the Changing the Buffer Size of an IPSG Association procedure.

  8. Add the associations using the ent-assoc command. For this example, enter this command.

    ent-assoc:aname=assoc2:lhost=gw107.nc.tekelec.com:lport=2000: rhost=gw100.nc.tekelec.com:rport=1030:adapter=m2pa

    These are the rules that apply to adding IPSG M2PA associations.
    1. The EAGLE can contain a maximum of 4000 connections (association – application server assignments).
    2. The default value for the adapter parameter is m2pa.
    3. A maximum of 32 IPSG M2PA or M3UA associations can be assigned to the IPSG card running on the E5-ENET/E5--ENET-B card or DEIR card. An IPSG application running on the SLIC card can contain a maximum of 128 associations.
    4. The value of the lhost, rhost, or alhost parameters is a text string of up to 60 characters, with the first character being a letter. The command line on the terminal can contain up to 150 characters. If the host names are too long to fit on the ent-assoc command line, perform the chg-assoc command with the parameters and values necessary to complete the entry of the IPSG M2PA association.
    5. To activate the association after the association is assigned to a signaling link, the association must contain values for the lhost, rhost, lport, and rport parameters.
    6. If the lhost and alhost parameters are specified, the lhost parameter value represents the IP address corresponding to one of the network interfaces (A or B) on the IP card while the alhost parameter value represents the IP address corresponding to the other network interface of the same IP card.
    7. The m2patset parameter can be specified only with the adapter=m2pa parameter.
    8. The m2patset parameter value defaults to M2PA timer set 1 (m2patset=1) if the m2patset parameter is not specified.
    9. When the adapter=m2pa parameter is specified, the RFC M2PA version is assigned to the M2PA association by default. If you wish to assign the Draft 6 M2PA version to this association, perform the Changing the Attributes of an IPSG Association procedure after this procedure is completed to change the M2PA version of this association.

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

  9. Verify the changes using the rtrv-assoc command specifying the association name specified in 8. For this example, enter this command.

    rtrv-assoc:aname=assoc2

    This is an example of possible output.

  10. Back up the new changes, using the chg-db:action=backup:dest=fixed command. These messages should appear; the active Maintenance and Administration Subsystem Processor (MASP) appears first.
