Hi community,
this is about TSW202 and KNX.
I started using the new managed switch TSW202 inside my IP-based KNX-environment, which looks like:
| KNX-IP Router A | <—> | TSW202 | <—> | TSW210 | <—> | KNX-IP Router B |
|---|---|---|---|---|---|---|
| (192.168.2.201) | (192.168.2.6) | N/A | (192.168.2.202) | |||
| <—> | KNX ETS Software | |||||
| (192.168.2.50) |
TSW202 operates with default configuration out of the box, except in the section “Network Interface”. “DHCP” instance is disabled, “Static” used instead. TSW202 has one Network Interface instance: 192.168.2.6/24 as “static”.
Firmware is the current one.
The issue is that there is no KNX-related communication possible anymore to KNX-IP Router A. I guess (!?) that this is somehow related to KNX using Multicast via 224.0.23.12 - the default address of KNX Multicast.
Accessing KNX-IP Router A from KNX ETS Software via Unicast works, but required a non-default configuration of ETS Software.
Formerly, I used two unmanaged switches and it worked properly.
Because I am new to managed switches, I would appreciate your feedback very much!!!
