1. vswitch Overview: A vswitch is a layer-2 device. However, as technology continues to improve, three-layer switches and multi-layer switches have emerged. This article describes some features of L2 switches. Ii. Functions of the vswitch: 1. Address Learning Some areas are also called source MAC address-based learning. This function is mainly used to learn and store MAC addresses. 2. Frame Forwarding/filtering Data Frame Forwarding is mainly because

An explanation of the parameter patterns of Oracle processes and functions

. You must have a location where the return value can be stored.The main difference between out mode and in-out mode is that in-out mode can pass the value of the actual parameter to the formal parameter of the procedure, and the initial value of the form parameter of the out pattern can only be null.Second, the value of the transfer and the referenceBy default, the default is in mode, parameter receives variables, constants, and arguments can be constants, variables, expression typesThe way the
