The value of this object is used for creating modifying or deleting frame relay ports. The possible values are : add(1) : Create frame relay port del(2) : Delete frame relay port mod(3) : Modify the frame relay port. This value is required to be set in Some Older Service Modules (FRSM-8T1/E1, FRSM-VHS, FRSM-HS2B etc) to modify the port parameters. In some service modules, when the port is successfully created(add(1)), this object is set internally to mod(3). The reason for this is, one can modify parameters of the port without requiring to go through an explicit mod(3) to modify the parameters.
