I have 2 powercoonect 6220 swwitchs

I made on the first switch a new vlan 2 and I joined port 7-14 with port 19 (external port) as untagged port to this vlan And left the default vlan as it is

I made the same on the other switch

Now I connect the default vlan on the first switch to the default vlan on the other switch

Things went just perfect

But when I connected vlan2 on the first switch to the vlan 2 o the other switch I faced a problem

I cant ping a computer from vlan2 on the first switch to the computer connected to the vlan2 on the other switch

Where is my problem --------any suggestion please

Thank u
