vsPlcRequiredCustomerParm 1.3.6.1.4.1.562.2.4.1.80.3.10.1.10

This attribute indicates the allowed customer defined parameter of the trunks on the route. Its value, a number from zero to seven, is chosen by network administration to have a meaning specific to their network, thus allowing them to customize the use of their trunks. A complementary trunk attribute, customerParameter, also has a value from zero to seven. The route selection process does not consider trunks whose customerParameter is greater than the requiredCustomerParameter of the path.
