Good evening!
*Sorry for bad english*
I have a task to change MTU on MikroTik ether1 interface from default 1500 bytes to 1700(for large packets through EoIP tunnel), i tuned it in interface settings and changed it on local switch(dlink dgs3620-28sc), but when i try to ping neighbor interface with no fragmentation it doesn't work. After testing i saw, that i can ping only with ping packet size 1534 and below. Jumbo frames on local switch is enable. Now there is firmware v6.42.6 (stable), but i tried to upgrade. Besides i have an 951Ui model too and all works fine. Can you prompt me what can i do with that?
