4.2 Configuration

4.2.1 VLAN 4.2.1.1 Static VLAN

This page shows information of static VLAN entries. User can add/remove static VLAN entries in this page.

Figure: 4.2.1

Parameter Description

Member The Port is a member of the specified VLAN and the frames of this VLAN can

be switched through this port, but the tagging information in the frame header

is not modified by the Switch.

Untagged The port is an untagged port (as defined in 802.1Q) that is participating in the

VLAN. In such an untagged port the Switch will strip off the 802.1Q tag from

the incoming and outgoing frames if they are tagged in such a way. This is

used for sending frames to non-802.1Q-compliant devices.

Tagged The port is a tagged port (as defined in 802.1Q) and is participating in the

VLAN. The Switch will put the VLAN information of the port – including VID

and Priority – into the header of the untagged frames coming in or transmitted

from the port. The tagged VLAN information in the frames can later be used

by other 802.1Q-compliant devices for forwarding decisions.

Not Member The port is not participating in the VLAN as identified by the selected VID(VLAN ID).

Note:

a.) Default VLAN with VIS being “1” cann’t be removed.

8

4.2.1.2 VLAN Setting

This page shows VLAN port information. User can assign PVID, tag egress mode, accepted frame type of

each port.

Figure: 4.2.2

Parameter Description

PVID Default PVID=1, User can assign new PVID for setting.

Set the VLAN ID. The limit is 1 to 4095. The VLAN ID is assigned to all

untagged frames received on this port.

Mode

(Tag Egress mode)

Tag Egress mode, accepted frame type of each port.

Original: - Output frame will follow VLAN untag setting.

Keep-format: - Output frame will keep original(VLAN or Un-Tag) format.

Priority-tag: - Output frame will be priority tag(Output frame is tagged with

VID=0).

9

4.2.1.3 Admin VLAN(option)

This page shows Administrator VLAN for CPU port. User can assign PVID, tag, accepted

management frame to CPU port.

Figure: 4.2.3

Note:

a.) Enable Admin VLAN will be apply to SNMP, Web, and ping etc. service.

10

4.2.2 QOS 4.2.2.1 Port-based Priority

This page shows port-based priority of each port. User can configure port priority with 4 priority level

of each port.

Figure: 4.2.4

4.2.2.1 Queue Weight

This page shows the priority to queue mapping. User can set the sixteen priority to queue mapping

of each priority.

Figure: 4.2.5

11

4.2.3 Service VLAN 4.2.3.1 TPID setting

Tag protocol identifier (TPID). With the IEEE standard 802.1ad, double-tagging can be useful for

Internet service providers, allowing them to use VLANs internally while mixing traffic from clients that

are already VLAN-tagged. The outer (next to source MAC and representing ISP VLAN) S-VLAN Tag

(service VLAN tag) comes first, followed by the inner C-VLAN Tag (customer tag). In such cases,

802.1ad specifies a TPID of 0x88a8 for service-provider outer S-VLAN Tag.

Figure: 4.2.6

The device determines whether a received frame carries a service provider VLAN tag (S-VLAN Tag)

or a customer VLAN tag (C-VLAN Tag) by checking the TPID value. After receiving a frame, the

device compares the configured TPID value with the value of the TPID field in the frame. If the two

match, the frame carries the corresponding VLAN tag.

Figure: 4.2.7

12

4.2.3.2 Uplink Port Setting

This page shows the device uplink port setting for handling Q-in-Q tag. User can set which port is

working for uplink port function.

Figure: 4.2.8

4.2.3.3 Static Service VLAN

This page shows information of Service VLAN entries. User can add/remove Service VLAN entries

in this page.

Figure: 4.2.9

13

4.2.4 IGMP The IGMP menu is used for configuring IGMP snooping. IGMP means "Internet Group Management

Protocol". It is a protocol through which hosts can register with their local router for multicast services. If

there is more than one multicast router on a given sub- network, one of the routers is elected and assumes

the responsibility of keeping track of group membership.

Figure: 4.2.10

14

4.2.5 Trunk Group Setting Port Trunking defines a network link aggregation and trunking method which specifies how to create a

single high-speed logical link that combines several physical links. Use the Trunk Configuration page shown

above to create trunk groups. The Switch supports a maximum of one trunk groups for 1000Mbps ports.

Each trunk group in groups may be comprised of up to four ports, selected from any combination of

1000Mbps ports.

Figure: 4.2.11

15

4.2.6 Loop Prevention The EMS5-8MA-SWITCH supports loop prevention function that can detect and relieve a loop situation of

Ethernet network topology. As long as loop condition is detected, the switch blocks the port automatically and

starts to blink the port Link/Act LED to indicate which port has been blocked to relieve a loop. When a loop

condition disappears, the port Link/Act LED returns to normal port property state automatically.

Figure: 4.2.12

16

4.2.7 Port-based Mirroring Set the port mirroring option to monitor data being transmitted through a specific port.

Figure: 4.2.13

Note:

Parameter Description

Mirror Direction Select appropriate mode

Disable: – Mirror mode is disabled

RX: – Monitor only incoming traffic

TX: – Monitor only outgoing traffic

Both: – Monitor both incoming and outgoing traffic

Mirroring Port Select the port which will do the monitoring.

Mirrored Port List Select the port that needs to be monitored.

17

4.2.8 Port Isolation This page shows the port isolation configuration. User can set isolation port mask of each port.

Figure: 4.2.14

Note:

Parameter Description

Port Select the physical port needs to be setting of Isolation.

Port Isolation List The port is isolated. Isolated ports belonging to the same VLAN(even untag) do

not communicate with each other – this is generally set for security reasons.

The isolated ports communicate only with the up-link ports, which should NOT

be set as “isolated”.

1: LAN 1 port; 2: LAN 2 port ; 3: LAN 3 port; 4: LAN 4 port; 5: LAN 5 port..etc.

Example:

LAN1 : Port 1 is Up-link port

LAN2~8: Can link to LAN1 port

LAN2~8: Can't communication each other port ; setting can be reference follow

18

4.2.9 Bandwidth Control This page shows the per port ingress/egress bandwidth control rate of each port.

Figure: 4.2.14

Note:

a.) before bandwidth setting, must select the port first.

b.) 1M = 1000k, 10M=10000k, 100M=100000k, 10000M=1000000k

c.) Apply only write to memory, Tools-save can write to CPU.

19

4.2.10 Jumbo Frame This page shows the maximum transmission unit (MTU) size of packet that the switch can receive/transmit.

User can change the MTU configuration in this page. The default maximum Jumbo Frame support 9216

Bytes.

Figure: 4.2.15

20

4.2.11 MAC Constraint The “MAC Constraint” mean the MAC Limit Configuration”. This page menu lets the user limit the number of

incoming MAC addresses per port. If the user wants to disable this function, select “Disable” from the

combo box “Mac Limit Function” on the upper left. The Limit Quantity range is 1~8192 per port. The MAC

addresses learned are recorded on a per-port basis. Only the frames with such recorded MAC addresses will

be forwarded. This learning process will be conducted every three minutes. So, if users change the NIC of

the PC or IP appliance, the new MAC address will be learned in three minutes by the Switch, within the set

quantity limitations. The MAC Constraint Limit Function can be disabled or enabled per port, under the

parameter labeled “Action” in the table. Generally this function is only enabled for downlink ports.

Figure: 4.2.16

21

4.2.12 Green Ethernet The EMS5-8MA-SWITCH provides link-on and dynamic detection of cable length and dynamic

adjustment of power required for the detected cable length. This feature provides high performance with

minimum power consumption.

The EMS5-8MA-SWITCH implements link-down power saving on a per-port basis, greatly cutting power

consumption when the network cable is disconnected. After it detects an incoming signal, it wakes up from

link-down power saving and operates in normal mode.

Figure: 4.2.17

22

4.2.13 EEE The Energy Efficient Ethernet (EEE) optional operational mode combines the IEEE 802.3 Media Access

Control (MAC) sub-layer with 100Bse-T and 1000Base-T Physical Layers define to support operation in Low

Power Idle mode. When Low Power Idle mode is enable, systems on both sides of the link can disable

portions of the functionality and save power during periods of low link utilization.

Figure: 4.2.18

23

4.2.14 SNMP User can use an external SNMP-based application to configure and manage the switch. This management

method requires the SNMP agent on the switch and the SNMP Network Management Station to use the

same community string. This management method, in fact, uses two community strings: the Read community

string and the W r i t e community string. If the SNMP network management station only knows the Write

community string, it can read and write to the MIBs (Management Information Bases of the devices), but, if

it only knows the Read community string, it can only read the MIBs.

Figure: 4.2.19

4.2.15 Provision(option) This function only support ODM/OEM customer.

24

4.3 Security

4.3.1 MAC Address 4.3.1.1 MAC Search This page display learned mac on LAN1 ~ LAN8. Since we need to search whole lookup table in system, this

page will delay few seconds to display mac entries.

Note2: a.) above sample rules mean MAC 00:90:96:55:23:60 entry will be Dropped even

from Port 3 and VID was 1. [black list]

26

4.3.2 Storm Control

Broadcast storms may occur when a device on your network is malfunctioning, or if application programs are

not well designed or properly configured. If there is too much broadcast traffic on your network, performance

can be severely degraded or everything can come to complete halt.

User can protect your network from broadcast storms by setting a threshold for broadcast traffic for each port.

Any broadcast packets exceeding the specified threshold will then be dropped.

Figure: 4.2.22

Parameter Description

Storm Type List the type of traffic which can be rate limited, including Broadcast,Multicast, Unknown Unicast and Unknow Multicast frames.

Port Port1, Port2, Port3, Port4, Port5, Port6, Port7, Port8

State OFF:disable storm control

ON: enable storm control

Rate (kbps) Rate: number of frame per second. The same threshold is key-in by user from 8-1000000kbps) to the per port setting.When the threshold is exceeded, packets are dropped, irrespective of the flow-control settings.

27

4.4 Monitoring

4.4.1 Port Statistics You can display statistics on network traffic from the ports. These statistics can be used to identify potential

problems with the switch (such as a faulty port or unusually heavy loading). All values displayed have been

accumulated since the last system reboot, but can be reset to zero by clicking the Clear button. The current

statistics are not displayed until you click the Refresh button.
