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

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.

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.

RJ-45 PORTS

The switch contains 16/24 100BASE-TX RJ-45 ports. All ports support automatic
MDI/MDI-X operation, so you can use straight-through cables for all network
connections to PCs or servers, or to other switches or hubs.

Each of these ports support auto-negotiation, so the optimum transmission
mode (half or full duplex), and data rate (10 or 100 Mbps) is selected
automatically.

Each port also supports IEEE 802.3x auto-negotiation of flow control, so the
switch can automatically prevent port buffers from becoming saturated.

REAR PANEL

The rear panel of the switch features a power socket and a grounding terminal.

Figure 3: SMCFS2401 Switch Rear Panel

GROUNDING TERMINAL

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.
