    Known Issues

    The known issues and limitations for vRealize Network Insight 3.4 are as follows:

    • The universal IPSets are not correctly annotated on the VMs and physical IPs in the flows of VMs associated with the secondary NSX manager.
    • vRealize Network Insight 3.4 does not support the rollback or product downgrade. It is recommended that you take a snapshot.
    • The NAT rules on NSX Edge version 5.5 or the previous versions are not supported.
    • The sub interfaces on VRF for Cisco Nexus 7000/9000 are not supported.
    • In the Applied To grouping criteria, the NSX edge is not supported.
    • The platform cluster does not support high availability (HA) configuration. All the platform nodes need to be up and running for the cluster to work at optimal performance levels.
    • The LDAP feature does not support restricting group access based on the Active Directory Primary Group.
    • The recommended firewall rules support only global rules creation. The universal rules creation is not supported.
    • The export as CSV is not supported for advanced searches that use group by, sum, max, and min functionality.
    • Some events such as Host network control plane mismatch are not raised if the datacenter is not at the top level and is located inside a folder in vCenter.
    • The NSX Manager data provider requires Enterprise role. If the central CLI is enabled, then the system admin user credentials are required for the NSX Manager data provider.
    • You must enable the NSX central CLI in the Settings page to get visibility into NSX NAT settings.
    • The product update notifications are supported only for single-platform node deployment that is connected to internet.
    • There is a known issue in events search list view where sometimes facet counts are incorrect upon selection and no events are shown.
    • The browser needs to be refreshed after clearing browser cache once the product upgrade is complete.
    • Upon Evaluation license expiry, the data providers are disabled and stop collecting data. After renewing license, the data providers must be enabled again from the UI to start data collection.
    • To use Gmail® server as the choice of Mail server, additional configuration settings as listed on https://support.google.com/accounts/answer/6010255?hl=en are required.
    • The export to CSV feature can export a maximum of 20,000 rows.
    • Once a data provider is removed from the system, the same data provider can be added back only after two or more hours.
    • The support bundle creation on a medium sized system can take in excess of fifteen minutes.
    • When the number of distinct 4-tuple flows exceeds 3 million within 24 hours, the processing of flow data on Proxy VM is paused.  It resumes only when number of active flows in the system are less than this limit. To reduce the number of flows, remove some of the vCenter data sources or disable IPFIX on some of the DVSs.
