The following table lists the mandatory attributes when creating a new linkset using RowStatus and multiple set commands. You must set the attributes listed in this table before you set the new linkset to active using RowStatus.

Although not a mandatory attribute, you should also set the CLLI description at the time of linkset creation to identify the linkset on the SS7 network. Alternatively, you can set this attribute after the linkset is created using RowStatus.

All other configurable linkset attributes listed in the MIB, such as timers, do not need to be set at the time of row creation. Default values are inserted for these attributes by the system at the time of row creation. For more information about the mandatory attributes and other configurable linkset attributes, refer to the MIB and the appropriate sections in SS7 Application Guide 1 and SS7 Application Guide 2.

Caution

If you omit any of the mandatory variables when creating a new instance of the variable using RowStatus, the procedure fails. You must delete the row and recreate it, ensuring that you include all mandatory variables.

Mandatory Linkset Variables

Variable OBJECT-TYPE Description
ptMTPLinksetAPC Enter the point code of the node on which this linkset resides as the APC value here. You must convert the point code into a 32-bit integer.

To add a Linkset (Example)

snmpwalk -c public <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.2

Get the list of all linksets on the system and display their APC.

APC object tag is 2 as per ptLinksetAPC OBJECT-TYPE in the MIB.

Parse the list to get the OID of the required Linkset.

  1. Set the RowStatus to 5 (create and wait).

    A linkset has MIB Object Identifier 53:

    ptMTPLinkset    OBJECT IDENTIFIER ::= {ptMTPLinksets 53 }

    snmpset -c private <host name> 
.1.3.6.1.4.1.3948.1556.17.15.46.65.64.53.1.1.254.1.1.1.1.0 i 5  

                

  2. Set the APC to ANSI 6.7.8.

    APC object type object tag is 2 as per ptLinksetAPC OBJECT-TYPE in the MIB. 6.7.8 must be entered as the decimal value (395016).

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.2.1.1.1.1.0 i 395016

              
    Data Link Type object tag is 3 as per ptMTPLinksetDataLinkType

    OBJECT-TYPE in the MIB.

    Set the Data Link Type to Action = 0 = mtp.

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.3.1.1.1.1.0 i 0

                

  3. Set the Parent OID.

    Note

    This OID is the same as the one you are creating without the current object type (Linkset53) and its instance (the last instance 0).

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.253.1.1.1.1.0 s
".1.3.6.1.4.1.1556.17.15.46.65.64.1.1.253.1.1.1.1"

  4. Check the RowStatus value.

    snmpget -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.254.1.1.1.1.0

    If the value is 2, the Linkset is ready to be created (To create SNMP Attributes)
     

  5. Create the Linkset by setting the RowStatus to 1 (Active).

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.254.1.1.1.1.0 i 1

                 

  6. Check if the Linkset was created.

    snmpwalk -c public <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.2

    Get the list of all linksets on the system and display their APC.

    Parse the list to get the OID of the required Linkset.
