mscAtmIfCANrtVbrSvcMpHoldingPriority 1.3.6.1.4.1.562.36.2.1.114.3.4.100.1.8

This attribute specifies the default holding priority which applies to SVC nrt-VBR point-to-multipoint connections. It takes a value from 0 (highest priority) to 4 (lowest priority). In a situation where the link bandwidth fluctuates, such as over an IMA link, holding priority is used to determine which connections are held and which are released. Holding priority 4 connections are the first to be released. Holding priority 0 connections are the last to be released. This attribute does not apply to Vpt Vccs. When bandwidth fluctuates, the entire Vpt, along with all Vpt Vccs is released as a unit, according to the Vpt's holdingPriority.
