Hello,   Last month I started having issues when I create a new vlan in a network (issue is not solved yet, but case has been opened) and this morning I have a second network in our organization where I observe the same. After the creation of the vlan, we lost connectivity to devices in other vlan's while the gateway ip's remained reachable. f.e.  I create a new vlan 6, ip 10.44.30.96/27 gateway-ip 10.44.30.126 I could not ping the gateway ip from the dashboard (using tools) which is already strange. Suddenly I start loosing clients, in other vlan's, I observed switches in other vlan's which became unreachable etc... Deleting the vlan solved the issue, all clients (pc/printers) are reachable again, error's disappear for wireless access points and switches in the portal.   I have this now already with two different networks in our environment and, on, different hardware platforms.   On one network our layer3 is running on MS210-48FP On the other network our layer3 is running on MS410-16   Both are on MS 14.33.1   I have not tried it on a 3th network yet ;-)... Anyone else observed the same ? ... View more
