Hello to all! I'm new in configuring switches and I would appreciate any help to solve my problem.
In our headquarter site we have a Meraki MX, two Meraki switches (an MS220 + an MS120) and an Hp maganed switch. The MX is connected directly to the MS220, MS120 is connected to the MS220 via fiber (SFP on the 220) and a media converter to ethernet on the 120, and the Hp is connected to the MS220 via fiber on the SFP.
In the past year we implemented VLANs, but we connected devices on the MS120 and hp only to the default VLAN. There were devices on to the other VLAN only connected via MS220.
Now I need another VLAN and to use it for devices either connected on the MS220, on the MS120 and the Hp.
I created the VLAN and set its gateway and DHCP.
If I assign a port of the MS220 to the new VLAN (Access mode), when I connect a device on that port everything works fine: IP assigned by DHCP on the correct subnet, access to the internet as expected.
If I do the same on a port on the MS120, when I connect a device it sets to a bad address 169.xxx.xxx.xxx and it's unable to connect to everything! The gateway port is Trunk (native VLAN the default), and on the port where I connect a device I tried to set it Trunk all VLAN allowed, Access on the new VLAN, Trunk only the new VLAN allowed and the new VLAN the default one, but no way!
Same on the Hp, where I configured the new VLAN!
Probably on the HP some additional configuration is needed, but on the MS120 I expected no problems!
Someone can help me?
Many thanks in advance!!
