Cloud-provided Red Hat instances typically require additional configuration before installing Session Manager Software-only ISO. For example, cloud provided instances often are deployed with DHCP enabled. Session Manager currently does not support DHCP so the OS needs to be configured before running the installer. This procedure covers the required changes to cloud-provided instances.
Important:
If net-snmp RPMs are installed before deploying the Session Manager Software Only ISO, remove net-snmp RPMs. If you do not remove net-snmp RPMs, the Session Manager Software Only ISO cannot install the Avaya custom net-snmp rpm and alarming does not work.
