Did you check the default gateway on the hosts ?

The default gateway on the hosts has to be the Vlan interface IP for each VLAN hosts. If you have correct vlan SVI configured as the gateway it should work.

Can we see the switch config along with ipconfig /all from one of the workstations ? FW enabled on the workstations ?

are all the hosts connected to this switch only?

Is this switch trunkie dany other switch?


you have SVI defined for VLAN 10,20,30,40 & 70 but vlans created are only 10,40 & 70

Did you verify the subnet mask matches on the workstation with the corresponding SVI ?

Can we see a 'ipconfig /all' from the workstation ?


Was this working before and suddenly stopped ?

As narayan said the way it is right now you would only be able to route between vlans 10,40 and 70 as you have no layer 2 defs for the others .
