Redmine OsmoBSC - Bug #4881 (Feedback): osmo-bsc with unixsocket to osmo-el2tpd fails to bring up rbs6k (...https://osmocom.org/issues/48812020-11-30T17:47:22Zfirs
<p>We have a working RBS 6k with a DUG 20, using a RRUS12 radio. With a DAHDI card and nightly build, the RBS comes up with osmo-bsc without issue. We obtained a TCU 02, configured it, and connected to osmo-el2tpd. The IDB of the DUG was changed to include the SIU in the transmission config. When running osmo-bsc, the BTS partially initializes, then errors come up like:</p>
<p><0016> lapd_core.c:2227 ((0:1-T0-S62)) Message 1/0 unhandled at this state LAPD_STATE_SABM_SENT<br /><0017> input/unixsocket.c:156 <abbr title="0:1">E1TS</abbr> no message available (line=0x55f005f3d7f0)</p>
<p>I have attached configuration files, pcap from both osmo-bsc and the ethernet interface that connects to the TCU. There are also log files from osmo-bsc and osmo-el2tpd.</p>
<p>The IP Configuration is:<br />TCU: 10.245.67.10/24<br />BSC: 10.245.70.15/24</p>
<p>There is a router between the two subnets.</p>
