[lldp-devel] Receiving PDUs from neighbours but not sending any

I have lldpad 0.9.43, as provided by Scientific Linux 6.3 (RHEL 6.3
clone). I want to be able to use lldptool to read information in PDUs
being sent by the switch the Linux machine is connected to.
I can see that the switch is sending out PDUs using tcpdump, but if I set
lldptool -L -i eth2 adminstatus=rx
lldptool get-tlv -n -i eth0 -V 1
...I get no output. If I enable transmitting my own PDUs with
lldptool -L -i eth2 adminstatus=rxtx
then I am told the neighbour's chassis ID as expected.
For various reasons I don't really want to send out my own LLDP PDUs, so
is it actually possible to configure lldpad only to receive, and not
transmit anything of its own?
