What is MPLS VPN on S series switches

MPLS VPN on S series switches (except S1700 switches):

The BGP/MPLS IP VPN model consists of the following parts:
Customer Edge (CE): an edge device on a customer network. A CE provides interfaces that are directly connected to an SP network. A CE can be a router, switch, or host. In most cases, CEs cannot detect VPNs and do not need to support MPLS.
Provider Edge (PE): an edge device on an SP network, which is directly connected to a CE. On the MPLS network, all handlings related to the VPN are performed on a PE, so the requirement on the PE performance is high.
Provider (P): a backbone device on an SP network, which is not directly connected to CEs. A P device only needs to provide basic MPLS forwarding capabilities, without maintaining VPN information.
PEs and Ps are managed by SPs. CEs are managed by users unless the users entrust CE management to SPs.
A PE can be connected to multiple CEs. A CE can be connected to multiple PEs of the same SP or of different SPs.
