Abstract
In one embodiment, ports of a network device are assigned to virtual service domains (VSDs). The ports are coupled to a virtual Ethernet module (VEM) of the network device. Each VSD is associated with one or more virtual service engines (VSEs) in a particular order. Each VSE is configured to apply a particular service to traffic traversing the VSE. Traffic received at a virtual Ethernet module (VEM) of the network device that is destined for a particular VSD, and is received on a port that has not been assigned to the particular VSD, is forwarded to the particular VSD via the one or more VSEs associated with the particular VSD such that the traffic traverses the one or more VSEs in the particular order.
