How the Call Home data is transmitted
Enabling Call Home provides a one-way communication that only transmits data and does not allow the appliance to receive any incoming data or notifications. All data that is transmitted to Veritas from an appliance is done with TLS-encrypted transmission by HTTPS PUT over port 443/tcp.
Starting with appliance software release 5.3. the AutoSupport client supports both TLS 1.3 and 1.2 protocols. If your SMTPS server and https proxy server support TLS 1.3, communication with the appliance is encrypted by default using the more secure TLS 1.3 protocol.
Data transmissions for the following services are sent to https://api.appliance.veritas.com:
Appliance Call Home Provisioning
Data Collect packages
Note:
If you configure a proxy server on the appliance, the proxy must allow connections to the above URLs to ensure that the AutoSupport feature can transmit data to Veritas.
The infrastructure consists of a set of endpoints with static IP address pools for data transmission.
Veritas highly recommends using DNS or fully qualified hostname resolution provisioning at the proxy and/or the firewall level to reduce the chance of possible service interruptions.
If your firewalls can only register entities by IP addresses the static endpoints retain their respective dedicated IP address pools.
On the appliance, make sure that you enable the proxy and/or the firewall to outbound 443/TCP TLS socket connections to the following site: https://api.appliance.veritas.com.
