About this task

You must configure CM for SLS using manual CLI entry of SLS administration. Perform the configuration during the initial administration of the host CM server.

Procedure

  1. Access the CM administrative SAT interface.
  2. At the SAT, enter change node-names ip to display the IP Node Names screen.

    For example:

    change node-names ip                                            Page   1 of 2
                                  IP NODE NAMES
    Name                 IP Address           
gateway1                 198.152.1.200                                                                                                     .   .   .
(X of X administered node-names were displayed )
Use 'list node-names' command to see all the administered node-names
Use 'change node-names ip xxx' to change a node-name 'xxx' or add a node-name
  3. Type the IP address of the Branch Gateway in the IP Address field.
  4. Submit the screen.
  5. At the SAT, enter change system-parameters mg-recovery-rule 1 to display the System Parameters Media Gateway Automatic Recovery Rule screen.
  6. Type a description of the rule in the Rule Name field.
  7. Set the Migrate H.248 MG to primary field to immediately.
    Note:

    The immediately value is only one of the four possible choices. See the Administrator Guide for Avaya Aura® Communication Manager for more information on the values for this field.

  8. Submit the screen.
  9. At the SAT, enter display media-gateway 1 to display the Media Gateway screen.
  10. Verify the following fields:

    • Name field (20 characters maximum) must match the administered name of the gateway.

    • Max Survivable IP Ext field only appears when the Type field is Gxxx .

      The current maximum product limits enforced by the SLS gateway’s firmware module is 150.

    These limits are enforced due to resource considerations in the given gateway.

    Important:

    Since the VoIP resources on the Branch Gateway are limited, the Max Survivable IP Ext field should not exceed these values.

  11. At the SAT, enter change station extension to display the Station screen.
  12. Verify that the following fields are correct:

    • Survivable GK Node Name

    • Survivable COR

    • Survivable Trunk Dest

  13. Submit the screen.
