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

All other configurable ATM link attributes listed in the MIB, such as debug levels, 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 ATM link attributes, refer to the MIB and the appropriate chapter in the 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 ATM Link Variables

Variable OBJECT-TYPE Description
ptMTPATMLinkSLC Read-only attribute that shows a code which uniquely identifies the link in the linkset and is a number from 0-15. If you want to change the SLC for an existing link, you must remove the existing link and then create a new link with the correct information. 
snmpwalk -c public <host name> 
.1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.5

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

CLLI object tag is 5 as per MIB ptMTPLinksetCLLI OBJECT-TYPE.

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

  1. Set the RowStatus to 5 (create and wait). (The last instance number is 0).

    A link has MIB Object Identifier 72:
    ptMTPATMLink                    OBJECT IDENTIFIER ::= { ptMTPLinkset 72 }

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.72.1.1.254.1.1.1.1.147971.0 i 5

               

  2. Set the mandatory attribute, SLC in the link's case.

    The value in this example is 1, which indicates SLC 1.

    SLC is object tag 3 as per MIB ptMTPATMLinkSLC OBJECT-TYPE.

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.72.1.1.3.1.1.1.1.147971.0 i 1

  3. Set the Parent OID.

    Tip

    This OID is the same as the one you are creating without the current object type (Link 72) and its instance (the last instance 0).

    snmpset -c private <host name> 
.1.3.6.1.4.1.1556.17.15.46.65.64.53.72.1.1.253.1.1.1.1.147971.0 s
".1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.253.1.1.1.1.147971"

             

  4. Check the RowStatus value.

    snmpget -c public <host name> 
.1.3.6.1.4.1.1556.17.15.46.65.64.53.72.1.1.254.1.1.1.1.147971.0
    Tip

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

        

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

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.72.1.1.254.1.1.1.1.147971.0 i 1

              

  6. Do a partial walk to verify the instance of the link to make sure it was created.

    snmpwalk -c public <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.72.1.1.254.1.1.1.1.147971
