GS1900-10HP - connection to VLAN trunk using a transparent bridge fails
I have Aruba 9004 gateway, Aruba 6200F switch and ZyXEL GS1900-10HP switch.
I have working VLAN configuration with 501,502,503,80 VLANs where Aruba 9004 is DHCP server. See the picture.
If I connect a CAT5E cable directly between Aruba 9004 port 3 and ZyXEL GS1900 port 9 Trunk, everything works and both ZyXEL and Aruba switches have VLANs available on configured ports and recieve IPs from DHCP.
As soon as I add a simple media converter (tried 3 different types - optics, VDSL) between Aruba 9004 and ZyXEL 1900, VLANs stop to work and no VLAN traffic passes through.
When I connect the same cable from media converter to a trunk port on Aruba 6200F, it works ok and VLANs are available on both ZyXEL and Aruba switches.
What could be wrong there?
Aruba 6200F switch

The problem was MikroTik S-RJ01 SFP Module, which is written to be 10/100/1G but appearently it did not work properly with SFP port of the ZyXEL switch, it did not negotiate speed well probably. Port 8 as trunk works well.
SFP port with MikroTik S-RJ01 also showed as Fiber on the homescreen - switch schema, probably either ZyXEL or MikroTik problem.0

Hi @Vodoca
You can try the Zyxel transceivers which are guaranteed to be compatible since they're fully tested and verified with our switch.
And the similar module with MikroTik S-RJ01is Zyxel SFP-1000T.
For other 3rd party ones, the compatibility is not guaranteed because there are numerous SFP in the market. It is impossible to verify all of them.
