Communication Manager notify synchronization

Last Updated : May 02, 2024 |

When you perform an administrative task from System Manager, the local database is immediately updated. If you do the action through a Communication Manager SAT screen, or through a phone, or from any of the several management applications such as Site Administration, MultiSite Administration, Native Configuration Manager, or MyPhone, it is not immediately reflected in System Manager. This scenario creates an out-of-sync condition between the Communication Manager and System Manager.

The CM notify sync feature provides:

  • Near-real time notifications from Communication Manager to System Manager whenever you run certain tasks against a Communication Manager object from a system other than System Manager

  • Notifications whenever the tti-m, tti-s, psa-u, psa-a, or psa-d login perform predefined actions against a Communication Manager station object.

After a Communication Manager sends notifications to System Manager, System Manager discovers the complete details of the task you preformed. The transmission of notifications in the form of event messages from Communication Manager to System Manager is based on the existing rsyslog capability of Communication Manager. rsyslog uses UDP or TCP to send event messages from the originating Communication Manager to the System Manager.

Note:

The daily default synchronization and any other scheduled synchronization operations are unaffected by the CM notify sync feature.

You need Communication Manager 6.2 or later to enable the CM notify sync feature. System Manager 6.3 supports one-way and two-way TLS.

Note:

If you log on to Communication Manager using SSH from a system with IPv6 address assigned and execute add/change/duplicate/delete commands on Communication Manager, Notify sync does not operate successfully.

You must log on to Communication Manager from a system with IPv4 address assigned for Notify sync feature to operate.

Enable the CM notify sync feature

You can enable and disable the CM notify sync feature on each Communication Manager. You can activate the CM notify sync feature on the Services > Inventory > Manage Elements page. You can select Communication Manager 6.2 or later, and select Enable Notifications in the General Attributes section.

Note:

System Manager resolves the host name or IP address of active and standby Communication Manager as configured on the Manage Elements page. You can check the logs on the Communication ManagerSAT screen in the /var/log/commandhistory file.

As a system administrator, you must specify the IP addresses of one or two System Manager servers to which Communication Manager sends the event data using rsyslog. If your configuration includes two System Manager servers, the standby System Manager ignores the syslog messages until the System Manager becomes active.

Configuring one-way and two-way TLS

You must configure one-way or two-way TLS for the CM notify sync feature.

To configure one-way TLS, perform the following:

To configure two-way TLS, do the following:
