Adding Communication Manager High Availability information

About this task

After you have associated a CLAN or Processor Ethernet host name or IP address with the switch connection, you may optionally populate the Survivability Hierarchy list. If your Communication Manager High Availability configuration employs the use of an Enterprise Survivable Server (ESS or survivable core server) or a Local Survivable Processor (LSP or survivable remote server), the ESS or the LSP should be added to the hierarchy. The Survivability Hierarchy list specifies the precedence of ESS or LSP nodes within the selected switch connection.

Procedure

  1. From the AE Services Management Console main menu, select Communication Manager Interface >Switch Connections.
  2. From the Switch Connections page, select the switch connection name you just added, for example, Switch2.
  3. Click Survivability Hierarchy
  4. On the Survivability Hierarchy page, if you want to allow the main Communication Manager server to take over as soon as it is online, uncheck the Remain connected to current active ESS/LSP when Main comes back online box. The Remain connected to current active ESS/LSP when Main comes back online box is checked by default.
  5. In the Cluster ID/MID field, type the cluster ID/MID of the new survivable node that you want to add to the Survivability Hierarchy table
  6. Click Append to add the new cluster ID/MID to the bottom of the hierarchy, or click Insert to add the new cluster ID/MID above the selected existing cluster ID/MID in the table.
    noteNote

    Inserting the new cluster ID/MID implies that all nodes at and below the selected entry will have their priorities changed in the Survivability Hierarchy table. The priority of each node will be increased by 1.

  7. Ensure that the correct cluster ID/MID is selected and click Edit PE IP.
  8. In the provided field, add host name or IP address of the Processor Ethernet associated with the ESS or LSP.
  9. Click Add/Edit Name or IP to save host name or IP address.
  10. Click Back to return to the Survivability Hierarchy page.
  11. Repeat steps 5-10 for each ESS or LSP to be added to the Survivability Hierarchy for this switch connection.
  12. Once all of the ESS and LSP servers have been added, click Back to return to the Switch Connections page.
