The following table lists the mandatory attributes required to create a new low-speed (LS) link in an  linkset using RowStatus and multiple set commands. You must set the Signaling Link Code (SLC), and the attributes required to map the LS link to a specific chassis, slot and channel for SS7 network connectivity before you set the new LS link to active using RowStatus.

You must reference a specific signaling channel to map the new LS link to a specific port and timeslot for SS7 network connectivity. For more information about channel mapping, see the appropriate chapter in the SS7 Application Guide 1 and SS7 Application Guide 2.

All other configurable LS link attributes listed in the MIB, such as debug levels, do not have 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 LS 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 LS Link Variables

Variable OBJECT-TYPE Description
ptSMTPLSLinkSLC Each LS link on a linkset must have a unique SLC. Enter the SLC value as an integer. Valid values: 0 to 15. Note: A maximum of 16 links can be configured for a linkset. 
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 ptLinksetCLLI 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 55:

        ptMTPLSLink                     OBJECT IDENTIFIER ::= { ptMTPLinkset 55 }

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.55.1.1.254.1.1.1.1.131841.0 i 5

                

  2. Set the mandatory attribute, SLC in the link's case.
    The value in this example is 4, which indicates SLC 4.
    SLC is object tag 3 as per MIB ptMTPLSLinkSLC OBJECT-TYPE.

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.55.1.1.3.1.1.1.1.131841.0 i 4

             

  3. Set the Parent OID.

    Note

    This OID is the same as the one you are creating without the current object type (Link 55) and its instance (the last instance 0).

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.55.1.1.253.1.1.1.1.131841.0 s
".1.3.6.1.4.1.1556.17.15.46.65.64.53.1.1.253.1.1.1.1.131841"

             

  4. Check the RowStatus value.

    snmpget -c public <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.55.1.1.254.1.1.1.1.131841.0

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

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

    snmpset -c private <host name>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.55.1.1.254.1.1.1.1.131841.0 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>
.1.3.6.1.4.1.1556.17.15.46.65.64.53.55.1.1.3.1.1.1.1.131841
