<div dir="ltr" align="left"><font color="#0000ff" face="Arial"><span class="739312011-28092016">Scott should jump in here with this one. But I
wonder if this has something to do with the "illegal Angelia MAC address" issue,
reported here previously, that causes problems with managed switches that will
reject such a MAC. Apparently, cheaper less sophisticated, unmanaged
switches will blissfully pass the illegal MAC and everything works fine
again.</span></font></div>

problems<br /></font><br /></div>
<div></div>I have an Angelia board that I purchased from Anan about 18 months
ago which I use as an SDR in my home 2m DX station on a 28MHz transverter IF and
also use in the field with our contest group.<br /><br />Currently I use the Angelia
primarily on RX with CuSDR as I like the UI design and display.<br /><br />The
problem that I have with the Angelia is that it appears to be very 'touchy'
(unreliable) with its Ethernet connection, obtaining a DHCP lease and talking to
my PC.<br /><br />In my setup I have:<br /><p></p><br /><span style="mso-spacerun: yes">�������� </span>1. my workstation PC - Dell T3610,
16Gb, 6-core Xeon, etc. with Gigabit Ethernet<p></p><br /><span style="mso-spacerun: yes">�������� </span>2. my Linux server which is my default
gateway and DHCP server<p></p><br /><span style="mso-spacerun: yes">��������
</span>3. my Angelia board<p></p><br /><span style="mso-spacerun: yes">�������� </span>4. Ethernet switch<br />�������� 5.
Various other devices (computers, VoIP phones,
etc)<p></p><br /><p></p><br />If I connect everything in the shack via an
old Netgear FS116 unmanaged 10/100Mbps switch then everything works fine - the
Angelia performs Ethernet link negotiation and comes up, sends DHCP request,
gets reply, sets up IP address, etc.<span style="mso-spacerun: yes"> after which
</span>running up CuSDR on the PC works when I hit 'Start' it performs
auto-detect, finds the Angelia and comes up...<p></p><br /><br />However this
network set-up isn't practical for a range of reasons...�� I have a rack of
servers in the garage and that's also where the internet comes in.�� I have have
a machine (called "gate") that provides network services, firewall, NAT, NTP,
DHCP etc. in the garage.<br /><br />I have my main PC, the wife's PC, network
printers, VoIP phones, etc. in the study/shack.�� At both ends there's a Netgeat
GSM724T 24-port switch and a Gigabit fibre trunk runs between the
switches.<br /><br />If I plug the Angelia and my shack PC in to two ports of the
switch in the shack and watch the DHCP server on gate with "dhcpdump" then I see
my PC perform DHCP request, get a reply and come up as expected but when I turn
the Angelia on I see nothing?�� What gives?<span style="mso-spacerun: yes">��
</span>Is the Ethernet implementation in Hermes and Angelia 'fragile' or
incomplete?<span style="mso-spacerun: yes">�� </span>Is there a problem with
link partner attributes? or timing when talking to managed switches<span style="mso-spacerun: yes">?�� </span>Does Hermes/Angelia assume that the link
comes up very quickly and transmit DHCP request(s) too soon or without
retries?<p></p><p></p><br /><br />Is there something that can be done about
this?<span style="mso-spacerun: yes"><br /><br />I really want to be able to use the
Angelia from one or other of two locations in the house on the same local
(switched) Ethernet.<br /></span><p><br />I'm happy to spend some time collecting
diagnostics/debug if this would help.<br /><br /><br />Regards<br /><br /><br />Mike
