Last week I installed new RB2011L-RM and Omnitik. Both connected to SMC switches. Both not working with them.
SMC switches were old model SMCGS24C-Smart and new SMCGS18C, both with latest firmwares.
I have another RB2011L(-IN) for testing on the table, problem is the same.
Link status LED indicate link up, everything look as usually, but no communication between them. I tried lot of patch cabels, crossed cables, tested connection to 1 Gbit part of mtik, 100 Mbit part, tried administratively slow down port from Gbit to 100 Mbit. I tried ROS 5.22, 6rc5, 5.17. I tried using HW switch chip in Mtik, without using switch chip (interfaces only in SW bridge). None of this work as I expect.
Mikrotiks and switches individually work (switchs) without problems. When I connect Mikrotik to nonmanagement old 100 Mbit SMC switch, all works normally.
I plan test RB2011 against SMC Tiger switch and D-Link smart switch.
Do anybody has experience with this problem (new Mikrotiks model vs SMC switches)?
I apologize for my bad english.
