1Introduction
The Ether-2416W web smart switch is a high performance web-smart Layer 2 switch that provides
users with switched 16 mini-GBIC fiber ports and 8 10/100/1000Mbps copper ports for building up
Ethernet network. This is specially designed for the use at the environment that needs high-density
fiber ports and copper gigabit ports simultaneously, such as big enterprise, big ISP and telephone
companies. When user adopts proper fiber transceivers, single-mode or multi-mode, he may
contracture a high speed backbone for large traffic data center or service center.
Web interface management provides control capability over TCP/IP, this make user convenient and
easy to manage switch with browser no matter at local or remote side.
Non-blocking and maximum wire speed performance are designed on all switched ports, and it also
supports auto-negotiation and MDI/-MDIX function on all switched 8 10/100/1000M RJ-45 Gigabit
ports, these function make user really easy to use and reduce the matching effort on straight and
cross-over line issues and on different speed setting.
This system supports both port-based VLAN and 802.1Q (tag-based) VLAN to catch-up the
application needed incoming VLAN age. To increase bandwidth application, it supports 4 trunk
groups with up to 8 member ports, and moreover, these trunk ports are with fair-over function to
provide redundant back-up when one or some ports are malfunctioned in that trunk group. In
addition to in-band management through RJ-45 ports, it also provides RS-232 terminal port with
command line interface (CLI) for user to do initial setting or operation while in-band domain is
malfunctioned.

1.1 Start to Manage This Switch
Plug-in the power source to power-up the switch. After the switch is powered-on and in ready state
(both the LED indicators POWER and DIAG are lighting), you can use any in-band Ethernet port to
remotely manage this system through the web browser, or use the RS-232 cable to plug-in the
console port (on the rear panel) to locally do the simple system configurations by using the
command line interface (CLI). The default IP and related settings for this interface are shown as
following:
IP address: 192.168.223.100
Network mask: 255.255.255.0
Default gateway:192.168.223.254
Try to use the default IP shown above to PING the switch from your PC to make sure the network
connection is successful. The default IP address on this switch can be modified later for your need. If
you encounter the access problem by using wrong IP addresses, just locally connect to console port
to get the correct IP address in this system.
Now you can use the browser to start to launch to the user-friendly web-managed interface for this
switch.
The login dialog box (shown as below) will show up first when the switch’s IP address is provided
through your browser.
Use the default username and password shown as below to complete the login procedure:
Username: admin
Password: 123
This username/password can be modified for your need.

2Configurations
2.1 Port Status
This page provides the current link status for all ports. You can select the Port Status menu to
activate this page and to refresh the current port status.
This page provides the following information:
Port – to specify aport on the switch
Link Status – to show the port link status: Up / Down
Speed / Duplex – to show the current link speed (1G / 100M / 10M bps) and duplex mode
(Full / Half) while the port is linkup.
NOTE: Only the full duplex mode is supported while the link speed is 1Gbps.
Flow Control – to show the flow control capability is Enable / Disable for this port.
The status for the two columns: Speed/Duplex and Flow Control won’t show up while the port link
is down. (The dash sign (‘--‘) indicates the status is unavailable to display.) Click the Refresh button
to manually get the most current link status for all ports.
If any trunk group is setup, a trunk group can be regarded as one logical port (e.g. Trk1 in above
figure is grouped by Port9 & Port10) which will show up just like the others. All the trunk member
ports won’t be displayed. Section 2.5 (Trunk) describes the port trunking in detail.

2.2 Port Configuration
If you need to do the port configuration, just select one desired port by clicking the Port number in
the Port Status page. Then the Port Configuration page (shown as below) for the selected port (e.g.
port3) will be opened:
The following parameters will be provided and configured in the Port Configuration page:
Port – the selected port number to be configured (read only)
Admin – to unblock/block the traffic for the port
¾Disable – to block all traffic for the port
¾Enable – to enable the bi-directional traffic for the port
Auto Negotiation – to enable/disable the capability of auto negotiation for setting up the link
¾Disable – to disable for the port (force mode)
¾Enable – to enable for the port (auto mode)
Speed / Duplex – to setup the link speed and duplex mode in force mode
The options for this function can be selected only when the Auto-Negotiation is Disabled (in
force mode) for copper ports (Port17 to Port24). At this moment, there are 4 options for this
parameter:
¾100Mbps Full – to set the speed 100Mbps in full duplex mode
¾100Mbps Half – to set the speed 100Mbps in half duplex mode
¾10Mbps Full – to set the speed 10Mbps in full duplex mode
¾10Mbps Half – to set the speed 10Mbps in half duplex mode
The following figure shows the options of Speed / Duplex while Disable is selected in
auto-negotiation field for copper port (e.g. Port17).

10
NOTE: Only full duplex mode is supported in 1Gbps link speed. For copper medium, this
system doesn’t support 1Gbps link speed in force mode; for fiber medium, only the 1Gbps
link speed is supported, but either auto or force mode can be set to build up the link.
Flow Control – to enable/disable flow control function
¾Disable -- to disable for the port
¾Enable – to enable for the port
Default Priority – to setup the priority of frames which will referenced in QOS function
¾0 – 7 – to set the priority level (range = 0 ~ 7)
Security – to enable/disable port security function
If the per-port security is enabled and if a received frame contains a source MAC address that
has already been learned in another port’s address table but not aged out, then the frame is
dropped. Otherwise, the address table entry is updated with the new port’s information and the
entry is updated.
¾Disable -- to disable port security
¾Enable – to enable port security
Jumbo Frame – to enable/disable jumbo frame function
If the per-port jumbo frame feature is enabled, the maximum frame size is 9216 bytes. In 100
Mbps mode, the maximum jumbo frame size supported is 9000 bytes
¾Disable -- to disable jumbo frame support
¾Enable – to enable jumbo frame support
After the desired options are selected for the above functions, click the Apply button to save the
current settings to the switch and back to the Port Status Page. Click the Cancel button to back to
Port Status page.

2.4 VLAN
VLAN function provides the capability of creating virtual LAN groups for network group
management, security and performance considerations. The main purpose of setting VLAN is to
limit the traffic only flow within the port members which belong to the same VLAN group. The
traffic including broadcast packets in a VLAN group will be isolated from different groups.
This system supports both port-based VLAN and IEEE 802.1Q (tag-based) VLAN. Port-based
VLAN provides the VLAN function only for local switch. Tag-based VLAN is capable of working
with other switches to achieve the VLAN function by tagged traffic.
Just click the VLAN menu item, the VLAN Configuration page is displayed shown as blow. This
page provides the current VLAN type and the place to do advanced VLAN configuration if the
Configure button is available.
Three options of VLAN type are provided:
Disable – to disable VLAN function. All existing VLAN groups will be removed. PVID for all
ports will be reset.
Port-based VLAN – to enable port-based VLAN. All existing tag-based VLAN group will be
removed. PVID for all ports will be reset.
IEEE 802.1Q VLAN – to enable tag-based VLAN. All existing port-based VLAN groups will
be removed.
The VLAN type can be either port-based or tag-based. That is, both the port-based VLAN and
802.1Q VLAN can’t co-exist at the same time.
The Configure button will be enabled to click for advanced VLAN configuration only when the
current VLAN type is activated to port-based or tag-based VLAN; otherwise, this button will be
disabled.

14
2.4.1 Port-based VLAN Configuration
The port-based VLAN divides the ports into different Virtual LAN domain groups. After setting the
port -based VLAN, the different VLAN groups can’t access each other. Like the different real LAN
can’t access each other. Before starting this configuration, it is required to set the VLAN type to
port-based VLAN first. Then click the Configure button after the port-based VLAN type is activated
(shown as figure below).
VLAN initial setting page is shown as below:
You can add, delete, and modify the port-based VLAN for your need. Currently this system supports
up to 32 port-based VLAN groups for manual entry. The next pages will be described in detail how
to configure the port-based VLAN.
NOTE: The default port-based VLAN group (No.1) always exists and can’t be removed. This
group needs to be manually maintained to make this function work properly. Initially, the
default group contains members for all ports. If a new group is created (e.g. port 1, 2, 3 as
members of group No.2) and this group wants to be isolated from the other ports, port 1, 2 and
3 in default group need to be manually set to “Not member” to make port-based VLAN group
No.2 available. Of course, manually set corresponsive port(s) to “Member” in default group as
your need if a group wants to be removed.

15
2.4.1.1 Add Port-Based VLAN Groups
To add a port-based VLAN group, select the “Create New VLAN” in VLAN NO dropdown of the
Port-Based VLAN Configuration page shown as below:
After selecting the Create New VLAN in the dropdown, the page will be changed like this:
In the above page, VLAN NO will auto setup. Users just need to set VLAN Port Members. After
setting complete, press the Create button will come back to the VLAN initial setting page. The
Cancel button can let user to give up the settings and back to the VLAN initial setting page.

16
Below is the example page when user sets Port1-12 to the VLAN Group2 after clicking the Create
button. Now there is a VLAN group No.2 created with the member Port1-12.
While the group No.2 is created, all the members in group No.1 are removed to availably operate the
VLAN function.

17
2.4.1.2 Delete Port-Based VLAN Groups
To delete a port-based VLAN group, just select a desired group (e.g. No.2) to be removed and click
the Remove This VLAN button to do the deletion.
After pressing the Remove This VLAN button and this action is confirmed, the result is in the
following figure.
Now all ports are set to the members in VLAN group No.1 to retain the system back to the normal
operation.

18
2.4.1.3 Edit Port-Based VLAN Groups
To edit the current port-based VLAN group, first select the existing group (e.g. group No.3 with
members from Port9 to Port12) you want to edit (to add Port7 & Port8 as members) and click the
Apply button to activate the setting.
The following figure shows the latest configuration for the selected group (e.g. No.3).

19
2.4.2 802.1Q VLAN Configuration
IEEE 802.1Q (tag-based) VLAN can add or strip 802.1Q tag depending on the requirements of the
individual transmitting port. It is required to click the VLAN menu item to set the VLAN type to
IEEE 802.1Q VLAN in VLAN Configuration page before doing the advanced configuration.
Click the Configure button to open the configuration page after the IEEE 802.1Q VLAN type is
activated (shown as figures below).
The group with VLAN ID 1 stands for the default 802.1Q VLAN group. This default group can’t be
deleted. However, the port members in this group can be modified. In default setting, all 24 ports are
the untagged members of this group with port VID value 1. Currently this system supports up to 32
tag-based VLAN groups for manual entry.
NOTE: Please be aware that this system currently has a constraint for web configuration in
802.1Q VLAN environment. This switch doesn’t allow web configuration from multiple VLAN
groups. That is, web configuration can be done through ONLY ONE specified VLAN group
(default VLAN group with VID=1 in default). Specify one VLAN group (e.g. VID=2) for
allowing to web-manage the switch and use console to set the PVID value (e.g. PVID=2) for
admin port (Port25), then web management can be achieved only through VLAN group
members with VID=2.

20
2.4.2.1 802.1Q VLAN Port Configuration
This page is to configure Port VID (PVID) for Untag port members and some ingress rules per port
basis to manipulate the packets related to the tag-based VLAN. Click the Port number (e.g. Port10)
to enter the 802.1Q VLAN Port Configuration page (shown as below).
The following figure shows the 802.1Q VLAN Port Configuration page by port. (e.g. Port10)
You can set the individual port for configuring the 802.1Q settings in the following fields:
¾PVID – enter a valid VLAN ID (1-4094), and PVID must be one of the existing VLAN group
ID. This parameter is useful for Untag port member.
¾UnTag Frame – Accept or drop incoming frames without VLAN tag.
¾Tag Frame – Accept or drop incoming frames with VLAN tag.
Finally, there are 2 buttons to select:
Apply: To submit the port configuration settings to the switch.
Back: To back to the 802.1q main setting page.
