please post the config of the router, the switch interface the router is connected to and the SVI of the switch associated with the physical interface.

ok , i moved the port to the corect vlan and i can ping the router from the switch.

From my workstation i can ping the 1.1 which is the core switch but cannot ping the 1.36 which is the router.

Not looking to steal points, just a general observations since the initial question was solved... If the workstation is not on the same subnet, I would check the route for your subnet on the router.

Verify that all the devies are on the same VLAN, or that there is inter-VLAN routing between the VLAN's.
