Hi!
I got three Cisco SG350 switches connected together via trunk ports and has two VLANS (10 and 20). 28 port version has four trunk ports (two RJ45 and two SFP module slots) and those have been connected to those 10 port versions trunk ports. Now I have a problem with DHCP server that is configured into SG350 with 28 ports. It does not give addresses to devices through trunk when connecting those to 10 port switches, but DHCP server seems to work fine when connecting directly 28 port switch. Odd thing is that if I use CAT-cables, DHCP does not work for smaller switches, but when using SFP fiber module, it does. Configuration is same for every trunk port. I use these switches for small AoIP systems only and those have been configured for that. Other bizarre thing is that audio (and few other things like discovery etc) does not work via CAT, but with fiber they do. Also one thing is that it has been working earlier via CAT also. I have tried to reset and load configurations back to switches, but nothing changes. Does anyone have idea what I should try next? If I remember correctly, I might have done configurations of ports 26 and 28 via wizard. Could that have some kind effect? If you ask why, I´m more of a sound guy so I wanted to see if my manual config would differ from wizards. When they both did work, I left it alone. Configs are below.
