vncsVpSetupPriority
vncs Vp Setup Priority
1.3.6.1.4.1.562.2.4.1.44.3.2.1.1
This attribute specifies the priority at which a path is established. Zero is the highest priority and four is the lowest. When PORS establishes a path through the network, it uses the setupPriority attribute to determine its potential for bumping established paths to acquire their bandwidth. The holdingPriority, a complementary attribute of this attribute, indicates the priority a path maintains once it is established. A new path can bump an existing path if the new path's setupPriority is higher (numerically less) than the existing path's holdingPriority.
