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) andis 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 showsAdministrator 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 anetwork 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 amaximum 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
