| | 5 | == I can't receive Group Address messages == |
| | 6 | |
| | 7 | When trying to read a Group Address from bus, with '''{{{pknyx-group.py}}}''' utility, you may get nothing. |
| | 8 | |
| | 9 | First, check that the used Group Address is correct, and there is a device configured to respond to a read request (use ETS for that). |
| | 10 | |
| | 11 | Second, depending on your network topology, you may have a dummy switch which forbids multicast frame beeing sent on all ports. I got this nasty behaviour with my Netgear GS116E. By default, there is a so-called ''intelligent'' option which only send multicast frames on ports where a machine joined the corresponding multicast IP. But this does not work! Setting this option to off fixed the issue. |
