3 — Management IP & System Name

3.1 Default IP

The default IP address is 192.168.0.1/255.255.255.0. If typing default IP at the url is unable to access Web page of Managed switch, please comply with the instructions described in section 1.1 and then change IP to the desired one by using the commands in red below：

Username: admin Password:

(Leave blank)

# configure terminal (config)# interface vlan 1

(config-if-vlan)# ip address 192.168.0.1 255.255.255.0 (config-if-vlan)# exit

(config)# exit

# copy running-config startup-config

3.2 Default Gateway

To access the Web page of Managed switch from different subnet, default gateway is required. To configure the default gateway via web interface,

Configuration  System  IP Fill in “Address” under “Default Gateway” ,Click the button “Set Default Gateway”  Click the button “Save” to take effect

(8)

Caution: To ensure data is saved in flash even after clicking “Save”, select Maintenance  Configuration  Press “Save Configuration” under save startup-config page.

3.3 Change IP Address

4 — SNMP Query & Trap

4.1 SNMP Query

The system supports SNMP function for version 1 to version 3. Before using this function, it needs to prepare a MIB browser and specific MIB files of the system. Below is a type of the MIB browser. It supports query function of the system in the first sheet.

To query the system, it needs to set the corresponding read and write community first. In this example, take default value as an example. See below setting.

Path: ConfigurationSecuritySNMPSystem System Setting:

Read community: “public” Set community: “private”

(11)

MIB Browser Setting:

Read community: “public” Set community: “private”

Next, type the system’s IP in the MIB browser.

Start to query any MIB file entry in the MIB Tree. See below.

(12)

4.2 SNMP Trap

The system supports SNMP trap including system, interface, AAA and switch events.

Before using this function, it needs to prepare a MIB browser. In the system, it needs to enable trap global settings, and add a new trap entry on the Web, see below:

Path: ConfigurationSecuritySwitchSNMPTrap

Trap configuration example:

Note: Trap Destination Address is MIB browser’s IP address.

(13)

Since the system selects trap destination port as 2000, it also needs to create this port in MIB browser. (Destination port can use default value 162 or user defined)

Start to trigger port link up and link down event, and check trap information received by MIB browser.

(14)

5 — Relay Output

The system supports relay output to indicate there is an alarm occurred. When an alarm occurs, the relay output will be closed. This makes alarm system execute some action to inform supervisor to remove alarm.

The relay output pins are between two powers. These pins are no polarity. Alarm relay output is open in normal state and is closed when an alarm occurs. The relay output supports maximum current is 1A at 24 volts.

(15)

6 — VLAN Configuration

Using 10-Port Managed switch as an example, Port 1 and Port 2 of the Managed Switches are connected within the Ring (in control network/level), whereas ports 4 and 5 are connected directly to PLC or other field devices (in field network/level).

In general, the ports connected to upper level (whether they are within a ring or not), they would be set to Trunk Port in VLAN configuration.

The ports connected to lower level (whether they are connected to field device directly or indirectly), they would be set to Access Port in VLAN configuration.

In above figure, SCADA collects RTU information through the 10- port Managed and Unmanaged Switches, the whole network (devices that connect directly to Managed Switch) communicates each other via VLAN 2.

Setup as below:

(16)

VLAN 2  set “Port VLAN” of Port 5 to 2 (please double confirm the “Mode” is “Access)

 Save

2) The ports of Managed switch connected to Ring are set to “Trunk”

Configuration  VLANs  select “Trunk” of “Mode”  Save

3) Ports 4 and 5 of Managed switch which connect with Unmanaged switches are set to Access port with support of VLAN 2

(17)

Configuration  VLANs  Allowed Access VLANs  enter “, 2 “ to add VLAN 2  set “Port VLAN” of Ports 4 and 5 to 2 (please double confirm the “Mode” is “Access)  Save

The VLAN configuration is settled!

(18)

7 — Ring / RSTP Configuration

Caution: Before setting I.A. Ring, please disable “Spanning tree” and “Loop Protection”

Disable Spanning Tree: Configuration -> Spanning Tree -> CIST Ports (left figure below) Disable Loop Protection: Configuration -> Loop Protection (right figure below)

(19)

7.1 Single Ring

As shown in above figure, Single Ring interconnects Managed Switches A, B and C

注意: Within a Single Ring, only one switch can be set to Master, the rest of switches are slaves.

For example, we select Switch B to be Master in this case, switches A and C are slaves.

To configure the Master switch

Configuration  I.A. Ring & Chain  ”Enable”  “Ring(Master) (if the ports connected to Ring are not ports 1 and 2, please select the proper “Ring Ports”)  In this case, we use ports 1 and 2 connected to Ring, no need to change  Save

(20)

To configuration Slave switches

Configuration  I.A. Ring & Chain  ”Enable”  “Ring(Slave) (if the ports connected to Ring are not ports 1 and 2, please select the proper “Ring Ports”)  In this case, we use ports 1 and 2 connected to Ring, no need to change  Save

(21)

To set VLAN to fulfill the ring if traffic runs on VLAN 2,

(22)

7.2 Rapid Spanning Tree (RSTP)

Note: The Spanning Tree protocol is enabled on each port by default

Basic Settings

Configuration  Spanning Tree  Bridge Settings  Select “RSTP” at “Protocol Version”  Select “61440” (lowest priority) at Bridge Priority  Save

To configure “Maximum Hop Count” only when the amount of devices within a RSTP Ring is greater than 20.

(23)

(Enable STP on ports connected to RSTP ring)  Save

(24)

8 — PoE Function

The system supports PoE function for connected powered device. The operation mode contains 802.3af (15.4W), 802.3at (30W), and 802.3at with 4 pair used (60W). 60 watt only can be applied for port 1 and 2. Each port has 5 classes for selection, class 0~4.

And, total power budget of the system is 120 or 240 watt.

Path: Configuration  PoE  PoE

Example:

Parameter Setting:

Reserved Power determined: Class

Power Management Mode: Actual Consumption

PoE Port Used: Port 1(with af), Port 2(with at)

PoE Status:

(25)

PoE Parameter Detail:

Reserved Power Determination

There are three modes for configuring how the ports/PDs may reserve power.

1. Class mode:

In this mode each port automatically determines how much power to reserve according to the class the connected PD belongs to, and reserves the power accordingly. Five different port classes exist and one for 4, 7, 15.4 or 30 Watts.

2. Allocated mode:

In this mode the user allocates the amount of power that each port may reserve.

The allocated/reserved power for each port/PD is specified in the Maximum Power fields.

3. LLDP-MED mode:

This mode is similar to the Class mode expect that each port determine the amount power it reserves by exchanging PoE information using the LLDP protocol and

reserves power accordingly. If no LLDP information is available for a port, the port will reserve power using the class mode

Note:

For all modes: If a port uses more power than the reserved power for the port, the port is

(26)

Power Management Mode

There are 2 modes for configuring when to shut down the ports:

1. Actual Consumption:

In this mode the ports are shut down when the actual power consumption for all ports exceeds the amount of power that the power supply can deliver or if the actual power consumption for a given port exceeds the reserved power for that port. The ports are shut down according to the ports priority. If two ports have the same priority the port with the highest port number is shut down.

Port Priority: Critical > High > Low.

When priorities are the same, low number of the port has higher priority.

2. Reserved Power:

In this mode the ports are shut down when total reserved powered exceeds the amount of power that the power supply can deliver. In this mode the port power is not turned on if the PD requests more power than available from the power supply.

(27)

Other Setting Parameter

1. PoE Power Supply

For being able to determine the amount of power the PD may use, it must be defined what amount of power a power source can deliver. Valid values are in the range 0 to 240 Watts.

2. PoE Mode

The PoE Mode represents the PoE operating mode for the port.

Disable : PoE disabled for the port.

Enable : Enables PoE for the port.

Schedule : Enables PoE for the port by scheduling.

3. Operation Mode

The Operation Mode represents the PoE power operating protocol for the port.

802.3af : Sets PoE protocol to IEEE 802.3af.

802.3at : Sets PoE protocol to IEEE 802.3at.

4. 4 Pair

The 4Pairs represents the 60W power supply for the port.

The option is only available when following rules are applied.

(28)

Enable : Enable 4Pairs to support 60W.

Disable : Disable 4Pairs to limit 30W of power.

5. PoE Priority

The Priority represents the ports priority. There are three levels of power priority named Low, High and Critical.

The priority is used in the case where the remote devices require more power than the power supply can deliver. In this case the port with the lowest priority will be turn off starting from the port with the highest port number.

6. Maximum Power

The Maximum Power value contains a numerical value that indicates the maximum power in watts that can be delivered to a remote device.

For port support 4Pairs mode, the maximum allowed value is 60 W; others are 30 W.
