Hello to everyone, Im engaged from my employ to do some advanced configuration on existing network. Im completely new to Meraki but have some expirience doing network administration. I have problem with vlan configuration. network: Palo Alto firewall 2 x MS425-16 in stack 5 x MS225-48 10 x MR56 Admins before me configured entire network in vlan 1 (servers, clients, meraki management IP...) and that is work fine. On stack is created switch vlan interface in default vlan 1 192.168.0.29 and global default route is 0.0.0.0/0 -> 192.168.0.1 (that is address of palo alto interface) The idea is to make more separate vlans like Guest, Users, Servers, Device Management with different subnets I created Guest switch vlan 20 interface on stack 192.168.20.1/24 with dhcp relay in 192.168.0.0 network where is server, and that is work fine. I wonted to make Management vlan for all Meraki devices in subnet 192.168.3.0 and i created switch vlan 3 interface on stack 192.168.3.1/24 after i change the ip address of all Meraki devices to appropriate IP address for examle 192.168.3.10 with default gateway 192.168.3.1 and put it in vlan 3 After i do that 15 of my devices resume working just fine but i lose connectivity with my core switches. (2 x MS425-16 in stack) I tried changing management vlan to vlan 3 in /switch/switch settings/vlan configuration option and did not help.. both switches are pingable from devices in the new vlan 3 but they are unreachable from dashboard and from any other device. After 2 hours they come back online with old configuration. (have some different trials where i again lose connectivity for 2h) I hope i provide enough information about the problem, if there is any information that i can provide i would do it. Thanx in advance.
