It seems that some TLVs that appear in the body of packets are unknown.
I'll debug which are the complaining tags and get back you.
Did you enable the 'use ip.access nanoBTS' flag in the protocol preferences
for the OML dissector? If you don't it will try to use the Siemens definitions
on an ip.access protocol trace (which will break).
Yes, the nanoBTS mode is enabled.
I've been debugging this a bit. The problem seems to be related with
"Activate Software" and "Activate Software ACK" messages. They
contain
an attribute whose tag is 0x42 which the dissector does not know how to
interpret.
Any clue on this?
