The following tables summarize resolved and unresolved issues.

Resolved issues

Issue or CR No.SeverityDescription
VTM-2356MajorNeed AUX Core ID validation for AUX Core ID values specified for an Aux Core.
VTM-2654MajorVUE alarm severity summary counts are incorrect for Service Groups in the Service Group inventory page.
VTM-2671MinorAll RxD, TS status/metric count attributes need to allow for 64 bit integer values.
VTM-2696MinorVTM 2.3 does not restart after reboot following installation.
VTM-2765MajorUnable to add a VUE system having no APP servers to VTM.
VTM-2780MajorWhen approximately 500 or more RMD devices sync from Domain Manager, RMD sync errors occur due to insufficient Java Heap Memory allocation. It should be increased from 256 MB to 512 MB.

Unresolved issues

Issue or CR No.SeverityDescriptionWorkaround
VTM-970MinorEntity names (Service Group, Service Catalog, Transport Stream and Frequency Templates, etc.) with a different case are not considered as duplicate entries throughout VTM screens.Case sensitivity must be considered when assigning entity name values.
VTM-1470MinorUpon importing Service Catalog Entries from a CSV file, VTM currently allows case insensitive values for “sourceType” and “pidType”.Ensure that the “sourceType” and “pidType” values align to any pre-existing Service Catalog Entry values in VTM.
VTM-2011MinorVARPD details are seen on RPD channel details screen for non applicable SG channels (DsScQAM, DsScte55-1).vARPD details should be disregarded for non UsScte55-1 channels.
VTM-2027MinorSelecting display column view options remain selected even if they are not applied to the current UI screen being viewed.Manually deselect the column display view options to match what is being displayed.
VTM-2045MinorAble to create a Downstream OOB Service Group having more than 1 frequency.OOB DS Service Groups should only be configured with one and only one Frequency channel. VTM will prevent this from happening during SG creation or modification. However, problems can arise if RPDs assigned to existing OOB SGs are attempted to be assigned to other existing OOB SGs with an OOB DS channel/frequency configured. If such a situation occurs, then the affected SGs would have to be recreated.
VTM-2080MinorOlder field values are retained on the TS template UI if navigated away from the UI screen without saving.Re-modifications are required in this case (and then saving).
VTM-2139MinorModulation mode value on the channel template is being over ridden by the Default value set on the SG channel config UI.Ensure the desired modulation mode is set before saving the SG. Especially, in the case where channels have been manually added and then a channel template has been applied.
VTM-2182MinorThe modulation mode on VUE channel is seen as QAM256 for a DSOOB channel.In the VUE system, the modulation mode is always defaulted to QPSK for SCTE55-1 DS channels.
VTM-2186MinorDeletion of last frequency from the frequency template is allowed.Re-edit the template with any desired frequencies.
VTM-2189MinorService catalog of type DS OOB should not support type PID as Service group of type DS OOB does not support the assignment of PID Service Catalog Entries (mappings).Attempts to assign PID catalog entries (mappings) to an OOB DS transport stream should not be attempted. Operationally, this is a not a valid scenario.
VTM-2213MinorThe NULL PID BW is allowed to be set via the Swagger (VTM) API for a DSOOB SG.Null PID B/W values/setting are not applicable to OOB DS transport streams and will have no effect if set via the VTM API. The VTM UI prevents Null PID B/W values from being set.
VTM-2217Minor In a TS template, leaving the null PID BW field as empty retains the previously added value.Re-edit the TS Template and assign valid null BW value.
VTM-2221MinorNo check present to avoid creation of an Aux core with duplicate name , Aux core id , and GCP IP address within or across VUE systems managed by the VTM.Ensure at least the Aux core name, id or GCP IP address is unique for all aux cores in a VUE system.
VTM-2224MinorACCP config status "Unknown" is not seen when the VUE is not reachable.There are cases where the config status of an aux core is not immediately reflected as unknown following an VUE system being unreachable, incorrect IP address assignment, etc. Subsequent sync operations will eventually result in the correct status being displayed.
VTM-2230Minor500 Internal Error seen on editing a VUE which has incorrect Username/password specified.Ensure valid/correct VUE credentials are used for VUE systems.
VTM-2306MinorVUE IP address specified using VTM is not being validated.Ensure a valid IP address is used when adding or modifying a VUE system.
VTM-2694MinorPID templates are incorrectly required to be associated with an AutoMap SCE.Create a PID Template with no PID entries and assign the PID Template to the AutoMap Service Catalog Entry.
VTM-2695MinorRF Channel Index Template should be modifiable on RxDs synced from Domain Manager.Currently, only the default RF channel index template can be used for RMDs synced from Domain Manager.
VTM-2697MinorPID Templates should not allow PID values of zero to be specified.PID 0 values should not be used. They are (by default) automatically mapped to the output transport streams by the VUE.
VTM-2770MajorThe VTM does not update the secondary (Geo Redundant) source information on VUE for a Service Catalog Entry (mapping).The VUE EM must be used as a work around.
VTM-2779MajorThe VTM does not process Input Transport Stream Redundancy Failover alarms.Since the failover alarms are not processed by the VTM, they can only be observed on the VUE Element Manager.
VTM-2839MajorSecondary Source Information (Multicast, Source IP) for Input Transport Stream Redundancy configuration is not validated for white space or invalid characters.Ensure valid IP and Multicast addresses are entered when configuring the secondary source information (i.e., no white space or invalid characters).
