@JKnott
I had a look inside the configfile. There you see this
<laggs>
<lagg>
<members>igb0,igb1</members>
<descr><![CDATA[LAGG TO 1G MAIN SW (GS1920)]]></descr>
<laggif>lagg0</laggif>
<proto>lacp</proto>
<lacptimeout>slow</lacptimeout>
<lagghash>l2,l3,l4</lagghash>
</lagg>
<lagg>
<members>ix0,ix1</members>
<descr><![CDATA[LAGG to 10G MAIN Switch (SX3008F)]]></descr>
<laggif>lagg1</laggif>
<proto>lacp</proto>
<lacptimeout>slow</lacptimeout>
<lagghash>l2,l3,l4</lagghash>
</lagg>
</laggs>
AND
<opt17>
<descr><![CDATA[Emerg_Mngt]]></descr>
<if>igb2</if>
<spoofmac></spoofmac>
<enable></enable>
<ipaddr>192.168.9.1</ipaddr>
<subnet>24</subnet>
<mtu>9000</mtu>
</opt17>
However there is no config block as show above for igb2 in favor of
igb0 / igb1 / ix0 / ix1
Neither is there such a config set for em0 .
The only situation where I see an ^<op117> like control blok, is in case of a "Physical LAN"
So adding not yet existing control block types, feels very hazzy
I think I will open a ticket. Lets see how the developers react ...
