Administering System Manager LHNR to resolve Presence Services Cluster FQDN to Avaya Breeze® platform Security Module IP address of remote data centers
Last Updated : Oct 28, 2020 |

Keywords:
To route messages correctly and in accordance with geo-location of servers, you must create appropriate LHNR records on System Manager. In a Geographic Redundant deployment, each Presence Services cluster FQDN has all the IP addresses of Avaya Breeze® platform nodes in both data centers. However, the priority of the IP address mapping to the local data center is higher than the priority of the IP address in the remote data center.
- Navigate to ElementsSession ManagerNetwork ConfigurationLocal Host Name Resolution.
- Click New.
STEP RESULT:The system displays the New Local Host Name Resolution Name Entries window.
- In the Host Name (FQDN) field, enter the Presence Services Cluster FQDN of local data center.
- In the IP Address field, enter the Avaya Breeze® platform Security Module IP address of the server from remote data center.
- In the Port field, type 5061.
- In the Priority field, enter a higher number (lower priority) compared to the same FQDN mapping to local Avaya Breeze® platform Security Module IP address.
- For the remaining fields, accept the default values.
- Click Commit.
ADDITIONAL INFORMATION:Note:For Session Managers to load-balance traffic efficiently, ensure that all high priority LHNR records have same value X and all low priority LHNR records have same value Y, where Y > X.
Consider the following details of geographically redundant data centers:
-
There are two data centers (Presence Services Avaya Breeze® platform clusters) in New York & Hong Kong.
-
Each cluster has two Avaya Breeze® platform servers.
-
Security module IP addresses of the server in New York are 192.0.2.10 and 192.0.2.20.
-
Security module IP addresses of the server in Hong Kong are 192.0.3.30 and 192.0.3.40.
-
Cluster FQDN of New York cluster is nyps.avaya.com.
-
Cluster FQDN of Hong Kong cluster is hkps.avaya.com.
Using the data center details, create eight LHNR records as shown in the table below.
