SVC Connections
An SVC is modeled in Cisco 12000/10720 Router Manager as an object deployed beneath two interfaces
(see Figure 12-2). The remote endpoint can be a non-Cisco EMF endpoint (that is, outside Cisco EMF))
or a Ci sco EMF-end point (tha t is , w ith in C isco EMF). Depl oying and cr ea ting an SVC cr ea tes a
connection between the outgoing port (or source) on one device and the incoming port (or destination)
on a second device.
