I cannot ping any of the other vlans except native vlan

i will paste show run at end

here is topology and output

I cannot ping any other vlan ~ I've made g0/0 into a trunk, as I'm trying to practice trunking and cannot seem to solve this basic thing as to why I can only ping vlan1 in this scenario

Only way I get it to work is to make G0/0 into access port - in this case it is pinging vlan 30 address

when I add an unmanaged switch in between managed switch and PC I maintain same

this could be limitation of VPCs; Usually I use this VPC connect to access port on switch; not trunking port; Normally only servers would connect to trunk directly; your home PC may work if your NIC supports 802.1Q tagging (most new NICs do)

So, with trunking and can only ping vlan1 - this would mean that VPCs does not support trunk interface;

It works fine with access port - then use access port between PC and switch; then trunking ports between switch - switch; if you want/need practice trunking, it should be done with switches anyway.
