Overview
| Introduction

IEEE 802.1P QOS

The SMCFS1601 and SMCFS2401switches support 802.1p priority queuing Quality of Service, which is an implementation of the IEEE 802.1p standard. With the 802.1p QoS function, network traffic that requires high priority, such as VoIP (Voice-over Internet Protocol), web browsing applications or video conferencing, can be forwarded before other traffic. The switches have separate hardware queues for each physical port, when packets are received with an
802.1p priority tag, they are sent to the appropriate output queue.
The illustration below shows how 802.1p priority queuing is implemented on the switches.
Figure 1: Mapping QoS on the Switch
Tag untag 0 1 2 3 4 5 6 7
Priority Level
Weight Value 1 2 4 8
TC0 TC1 TC2 TC3
There are four priority levels labeled TC0, TC1, TC2 and TC3. The untagged packets and the eight IEEE 802.1p priority tags (defined by the standard) are mapped to the four priority queues on the switch. TC3 has the highest priority of the four priority queues while TC0 has the lowest priority. The untagged packets and eight priority tags, specified in IEEE 802.1p, are mapped to the switch’s priority tags as follows:
Untagged packets, and packets with priority tag 1 and 2 are assigned to the
switch’s TC0 level queue.
Packets with priority tag 0 and 3 are assigned to the switch’s TC1 level
queue.
Packets with priority tag 4 and 5 are assigned to the switch’s TC2 level
queue.
Packets with priority tag 6 and 7 are assigned to the switch’s TC3 level
queue.

| Introduction
Overview
The SMCFS1601 and SMCFS2401 switches use Weighted Robin Round (WRR) for scheduling. The WRR queue-scheduling algorithm schedules all the queues in turn with every queue assured a certain service time. For both WFQ and WRR mode, the default weight values of TC0, TC1, TC2 and TC3 are 1:2:4:8.

Connecting Network Devices

| Installing the Switch
CONNECTING NETWORK DEVICES
The switches are designed to be connected to 10, or 100 Mbps network cards in PCs and servers, as well as to other switches and hubs.

CABLING GUIDELINES

The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5 or better for 100BASE-TX connections, and Category 3 or better for 10BASE-T connections.

CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES

1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.
2. Attach the other end of the cable segment to an available port on the
switch.
Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.
3. As each connection is made, the relevant port LED (on the switch)
corresponding to each port will turn on green to indicate that the connection is valid.
