This describes the pseudowire's topological role: mesh(1) for a full-mesh VPLS-style pseudowire among multiple sites, spoke(2) for a point-to-point/hub-and-spoke pseudowire, or switching(3) meaning this PW is actually one leg (segment) of a multi-segment pseudowire (MS-PW) that gets switched to another PW segment at this node rather than terminating here. Knowing the mode is essential to understanding what down even means for this PW -- a switching-mode segment being down implies a break somewhere along a longer end-to-end chain of PW segments, not necessarily at either ultimate endpoint. If this PW's mode is switching(3), the admin should also check the related peer-PW objects, like cienaCesMplsMsPwPeerPwName, to see the other segment this one is stitched to.
