POE FEATURES
The SMCGS1601P can provide up to 30 Watts of power to attached devices, such
as VoIP phones, wireless access points, surveillance cameras, etc, all over
existing Cat. 5 cables. The switch can deliver up to 30 Watts on 8 ports, or 15.4
Watts on 16 ports. This eliminates the need for individual power sources for
devices in the network, saving on costs for power cables and avoiding power
outlet availability issues.
IEEE 802.1PQOS
The SMCGS1601P switch supports 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 switch has 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.

C HAPTER 1 | Introduction

◆Packets with priority tag 6 and 7 are assigned to the switch’s TC3 level
queue.
The SMCGS1601P switch uses 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.
