<title>Known Issues and Limitations in this Release</title>
<itemizedlist>
<listitem>
<para><remark>ELCCR-1688, ELCCR-1809</remark>It is possible to end up
with a corrupted VM image from the download operation. If that happens,
the VNF instantiation will fail. The corrupted image has to be manually
removed from <literal>/var/odm/vm_images/startup/</literal>.</para>
</listitem>
<listitem>
<para><remark>ELCCR-1753</remark>When using tap interfaces for
communicating over the bridge, port numbers assigned to VM interfaces
can change when the VMs are restarted. The only currently known
workaround is rebooting the uCPE device.</para>
</listitem>
<listitem>
<para><remark>ELCCR-1999</remark>Attempting to upload multiple files
simultaneously (e.g. a VNF image and custom scripts) in the Enea Edge
Management application will cause all upload operations to be canceled.
In order to avoid this limitation, please wait until any previous upload
finishes before initiating a new one.</para>
</listitem>
<listitem>
<para><remark>LXCR-10922</remark>A very rare error on certain Atom C3000
boards makes X553 SFP+ Ethernet ports unusable until a target cold reset
is performed. When the error occurs in Enea Edge Runtime 2.5.0 or later,
there will be a warning printed into the console by the
<literal>ixgbe</literal> driver:</para>
<programlisting>[11.361580] ixgbe 0000:0a:00.0: Warning firmware error detected FWSM: 0x8010801A</programlisting>
<para>The only currently known workaround for this issue is a cold
reset.</para>
</listitem>
<listitem>
<para><remark>ELCCR-474</remark>Deleting VNF instances with flows
configured on the OVS bridges can be done only after removing the
flows.</para>
</listitem>
<listitem>
<para><remark>ELCCR-527</remark>Canceling a file upload in the Enea Edge
Management application will require the user to close and reopen the
upload window for the next upload to work.</para>
</listitem>
<listitem>
<para><remark>ELCCR-572</remark>Sometimes when selecting and deleting
more than one VNF instance simultaneously, an error message might be
triggered, even if the delete operation succeeds.</para>
</listitem>
<listitem>
<para><remark>ELCCR-577</remark>If the Enea Edge Management application
is restored from a backup made on a release version older than Enea NFV
Access 2.2.3, VNFs cannot be instantiated from the GUI.</para>
</listitem>
<listitem>
<para><remark>ELCCR-847</remark>The Juniper vSRX VNF cannot be
instantiated on the Xeon-D architectures due to missing CPU features in
the VNF's domain XML. This impacts all example use cases where the
Juniper VNF is used.</para>
</listitem>
<listitem>
<para><remark>ELCCR-912</remark>When the Enea Edge Management
application is installed on CentOS 7, prior to C7.1804 (kernel version
3.10.0-862), adding an upgrade image fails. As a workaround, please
update <literal>glib2</literal> to version 2.54.2 or later, using
<literal>#yum update glib2</literal>.</para>
</listitem>
<listitem>
<para><remark>ELCCR-1468</remark>When using the Enea Edge Management
application in HTTPS mode, upgrading a device from NFV Access 2.3.0 is
not possible. Either switch to HTTP mode (for more details see <olink
targetdoc="book_enea_edge_getting_started"
targetptr="device_up_process">The uCPE device Upgrade Process in the
<xi:include href="../../s_docbuild/olinkdb/pardoc-names.xml"
xmlns:xi="http://www.w3.org/2001/XInclude"
xpointer="element(book_enea_edge_getting_started/1)" /></olink> Manual)
or install it manually.</para>
</listitem>
<listitem>
<para><remark>ELCCR-1497</remark>If the Enea Edge Management application
has an incorrect database configuration, when performing an
uninstallation, the Tomcat instance and Watchdog service will not be
stopped automatically. Instead, they must be killed explicitly.</para>
</listitem>
<listitem>
<para><remark>ELCCR-1565</remark>Before starting an Enea Edge Management
upgrade, any owned Tomcat certificates should be manually copied into
the
<literal>/opt/ems/ucpemanager/application/config/certificates</literal>
folder.</para>
</listitem>
<listitem condition="hidden">
<para><remark>LXCR-3283</remark><emphasis role="bold">PDF
navigation</emphasis>: When using links to open other PDFs, or jump to
another place in the same PDF, jumping back sometimes fails. This has
been observed when opening a PDF in Adobe Reader, inside a browser with
PDF add-on, as well as when the browser is configured to open PDF files
in an external PDF reader. As a workaround, open the HTML version of the
document.</para>
</listitem>
<listitem>
<para><remark>LXCR-9799</remark>Proper boot order is not ensured if a
uCPE device has more than one HDD attached.</para>
</listitem>
<listitem>
<para><remark>LXCR-9853</remark>The WAN interface of a uCPE device needs
to be connected to a network with at least a router/gateway installed
for next-hop communication.</para>
</listitem>
<listitem>
<para><remark>LXCR-9904</remark>Enea Edge Runtime cannot be installed on
USB storage devices.</para>
</listitem>
<listitem>
<para><remark>LXCR-9992</remark>Depending on hardware capabilities,
there are certain limitations regarding the <literal>vfio-pci</literal>
and <literal>igb_uio</literal> drivers. While the Enea Edge Runtime uses
the <literal>vfio-pci</literal> driver by default, for certain hardware
configurations, <literal>igb_uio</literal> should be used instead, by
providing custom scripting. Please contact Enea for further
details.</para>
</listitem>
<listitem>
<para><remark>USERDOCAP-641</remark>Enea Edge does not have support for
IPv6 addresses on both uCPE devices and the Enea Edge Management
installation.</para>
</listitem>
<listitem>
<para><remark>USERDOCAP-648</remark>The <literal>storage size</literal>
parameter on the VNF onboarding page is ignored. The default storage
size specified when creating the VM image is used when instantiating the
VM and when presenting VM information.</para>
</listitem>
<listitem>
<para><remark>USERDOCAP-651</remark>Wireless AP configuration is
optimized for wireless modules that use the <literal>ath10k</literal>
driver. Using other wireless modules may result in undefined
behavior.</para>
