Zarlink Semiconductor Inc.
The VLAN Index port association table is used by both software and hardware. It contains 256 entries. Each entry
has 27 fields, such that each field represents the port status of that particular VLAN.
Table 2 - LAN Index Port Association Table
Each entry has 64 bits. Each port has a VLAN status field with the following two bits values:
00: Port not a member of VLAN
01: Port is a member of VLAN, and is subject to aging (Do not use. Used by the aging module)
10: Port is a member of VLAN, and is subject to aging
11: Port is a member of VLAN, and is not subject to aging
Note:
The VLAN aging time is controlled by register 402h.
5.4 MAC Address Filtering
The MVTX2604's implementation of intelligent traffic switching provides filters for source and destination MAC
addresses. This feature filters unnecessary traffic, thereby providing intelligent control over traffic flows and
broadcast traffic.
MAC address filtering allows the MVTX2604 to block an incoming packet to an interface when it sees a specified
MAC address in either the source address or destination address of the incoming packet. For example, if your
network is congested because of high utilization from a MAC address you can filter all traffic transmitted from that
address and restore network flow while you troubleshoot the problem.
5.5 Quality of Service
Quality of Service (QoS) refers to the ability of a network to provide better service to selected network traffic over
various technologies. Primary goals of QoS include dedicated bandwidth, controlled jitter and latency (required by
some real-time and interactive traffic) and improved loss characteristics.
Traditional Ethernet networks have had no prioritization of traffic. Without a protocol to prioritize or differentiate
traffic, a service level known as “best effort” attempts to get all the packets to their intended destinations with
minimum delay; however, there are no guarantees. In a congested network or when a low-performance
switch/router is overloaded, “best effort” becomes unsuitable for delay-sensitive traffic and mission-critical data
transmission.
