2.5.3 Port Mirroring

I. Port mirroring introduction

The S1526 supports the port mirroring function. With this
function enabled, a copy of the data on one or more ports can
be forwarded to the monitor port for traffic analysis and
monitoring. For example, you can copy the packets on port 2 to
the designated monitor port 1, so that you can analyze the
traffic and record the working status of port 2 by using the
protocol analyzer connected to port 1.

II. Monitor port configuration

Click [Port/Port Mirroring] to enter the [Port Mirroring
Settings] page as shown in

Figure 2-14. Follow these steps:

port] option button is selected, this port will not be set
as a mirroring port. Note that a port cannot be
configured as a monitor port and a mirroring port at the
same time.

4) Choose the inbound/outbound direction of the
mirroring port:

z Inbound: only the incoming packets on the port will be

mirrored to the monitor port;

z Outbound: only the outgoing packets on the port will

be mirrored to the monitor port;

z Both: both the incoming and outgoing packets on the

port will be mirrored to the monitor port.

5) Click <Apply> to complete the configuration.

2.5.6 Broadcast Storm Control

With the broadcast storm control function enabled, if the
broadcast traffic exceeds the predefined limit, the system will
drop broadcast packets beyond the limit until the ratio of
broadcast packets comes down to a reasonable value. In this
way, broadcast storms can be effectively controlled and
network congestion can be avoided, thus ensuring the smooth
operation of the network.

Click [Port/Broadcast Storm Control] to enter the
[Broadcast Storm Control] page as shown in

Figure 2-19.

Follow these steps:

1) Select [Disable] or [Enable].

2) If you select [Enable], the broadcast storm control
function will be enabled. You can then select the rate
of broadcast storm control, which can be 5%, 10%,
20% or 100%. The smaller the percentage is, the
lower broadcast traffic will be permitted to pass. 100%
means no control.

2.6 VLAN

Virtual local area network (VLAN) is a technology that
allows you to assign network segments to devices within a LAN
logically rather than physically, to create virtual work groups.
With the VLAN technology, the network administrator can
divide a physical LAN into different broadcast domains (namely,
VLANs) logically, with each VLAN consisting of a group of
computers having the same needs. Since VLAN is divided
logically rather than physically, computers in the same VLAN
do not need to be located in the same physical area. In ot her
words, these computers do not have to belong to the same
physical LAN segment.

2.7 QoS

2.7.1 QoS Introduction

The S1526 supports basic QoS function. With proper port
priority settings, when network congestion occurs, the system
first drops packets on ports with lower priorities to ensure the
transmission of packets on ports with higher priorities. The
switch supports 4 queues, with queue 0 having the lowest
priority and queue 3 having the highest priority. The queue
scheduling algorithm supported by the switch is Weighted
Round Robin (WRR).

2.7.2 QoS Configuration

Click [QoS] on the menu bar to enter the [QoS
Configuration] page, as shown in

Figure 2-29. Set the mapping

relation of queues and priorities, and the weight, whose value
can range from 1 to 15. Click <Apply> on the right to complete
QoS configuration.

For example, as shown in

Figure 2-29 , set packets with

priorities 0 and 1 in queue 0, packets with priorities 2 and 3 in
queue 1, packets with priorities 4 and 5 in queue 2, and packets
with priorities 6 and 7 in queue 3. Set the weight values for
queues 0, 1, 2, 3 to 1, 2, 4, 8 re spectively. With this setting, if
packets in queues 0, 1, 2, 3 congest on a port, the port will send
the packets according to a traffic ratio of 1:2:4:8.

4.1 Network Requirements

Company A wants to establish a local-area network (LAN)
by using the S1526 switch. PCs of the Finance Dept., which
can only be used for inner purpose and cannot have Internet
access, must be isolated from PCs of other departments, which
require Internet access by connecting to an uplink switch
through the S1526 and an uplink speed of 2 Gbps. In addition,
the S1526 should be able to be managed remotely by a
management computer.

To meet the network requirements above, we can design
the network in the following way:

z Use a S5000P switch as the uplink switch of the

S1526.

z Set the VLAN type to 802.1Q VLAN.

z Assign ports 1 to 4 (100 Mbps) to four PCs of the

Finance Dept., and add ports 1 through 4 to VLAN

200.

z Assign ports 5 through 24 (100 Mbps) to the 19 PCs of

the other departments and add these ports to VLAN

10.

z Add ports 25 and 26 (1000 Mbps) of the S1526 to

VLAN 10 and VLAN 1 (default management VLAN).
Connect port 25 and port 26 to the S5000P
respectively.
