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.
Page 12

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).

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
Page 16

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
Page 18

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
Page 19
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.

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

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
Page 26
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
Page 27
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 Write 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.
