Switch Functional Description
The standard Firmware together with the switching Hardware and, optionally, MAC Cores
from MorethanIP already provides a complete Ethernet switching solution. As the Switch
Firmware is developed in a modular way, MorethanIP can implement, upon request, specific
functions like for example, Spanning Tree)
The Hardware and Software designs of the switch are also highly tightly optimized together
to provide high performances and to be scalable to higher throughput switching solutions.
29.4.2.1 Overview
The VLAN input processing function is used on each switch input port to inspect and
manipulate the VLAN tag of frames entering the switch. It performs the following functions:
Based on the information of the Input Processing function, the frame can be switched to
the corresponding output port or will be discarded.
29.4.2.2 Terms and Definitions
VLAN Information: The 16-bit field following the VLAN type field within a frame.
VLAN-ID: The lower 12 bits of the VLAN information field.
VLAN-Priority: The upper 3 bits of the VLAN information field. Used to prioritize incoming
frames. A value of 0 represents lowest priority, a value of 7 represents highest priority.
29.4.2.3 Configuration Information
The switch management provides the following information to configure and control the
operation of the function:
