Purpose
This manual gives specific information on how to operate and use the SMxTAT2SA management
functions with an HTTP/HTTPs web browser.
Audience
This manual is intended for use by network administrators who are responsible for operating and
maintaining network equipment; it assumes a basic working knowledge of general switch functions,
the Internet Protocol (IP), and Hypertext Transfer Protocol (HTTP).
Note: See the Install Guide for important Cautions and Warnings.
Related Manuals
For Transition Networks Drivers, Firmware, Manuals, etc. go to the Product Support webpage (logon
required). For Application Notes, Brochures, Data Sheets, Specifications, etc. go to the Support
Library (no logon required). Note that this manual provides links to third party web sites for which
Transition Networks is not responsible. This manual describes how to install, configure, and
troubleshoot the SMxTAT2SA switch. Other related manuals are listed below.

Chapter 1 - Web-based Management
Initial Configuration
This chapter describes how to configure and manage the SMxTAT2SA via the web user interface.
With this facility, you can easily access and monitor through any one port of the switch all the status
of the switch, including each port activity, Spanning tree status, port aggregation status, multicast
traffic, VLAN and priority status, even illegal access. SMxTAT2SA default values are:
IP Address 192.168.1.77
Subnet Mask 255.255.255.0
Default Gateway
192.168.1.254
Username admin
Password admin
After the SMxTAT2SA interface has been configured, you can browse it.
For instance, type http://192.168.1.77 in the address row in a browser; it will show the Login screen
and ask you for a username and password in order to login and access authentication.
The default Username is admin and default Password is admin. For first time use, enter the default
username and password, and then click the <Login> button. The login process now is complete. In
the login menu, you must enter the complete username and password respectively. The SMxTAT2SA
allows two or more users using administrator’s identity to manage this switch; the administrator to
do the last setting will be the configuration to affect the system.
Note: When you login to the switch Web page to manage, type the Username admin and press
the <tab> key. Then type the Password admin and press Enter. When you login to the switch Web UI,
you can use IPv4 or IPv6 login to manage.
To optimize the display effect, we recommend Microsoft IE 6.0 above, Netscape V7.1 above or
Firefox V1.00 above with 1024x768 resolution. See the SMxTAT2SA Install Guide for Web browser
support.
Note: The SMxTAT2SA has the DHCP function enabled by default, so if you do not have a DHCP
server to provide an IP addresses to the switch, enter the default IP 192.168.1.77

Web Interface
To configure IP settings in the web interface:
1. Click System, IP Address, IP Settings.
2. Check the “IPv4 DHCP Client Enable” box.
3. Enter the IPv4 Address, Subnet Mask, Gateway, and DNS Server parameters.
4. Click Apply.
Figure 3-2.1: The IP Settings page

(configured in the following section “Advanced IP Settings”.
Buttons
Apply: Click to save changes.

3-2.1 Advanced IP Settings
The IPv4 address for the switch can be obtained via DHCP Server for VLAN 1. To manually
configure an address, you must change the switch's default settings to values that are
compatible with your network. You may also need to establish a default gateway between the
switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page and configure IP basic settings,
control IP interfaces and IP routes. You can configure up to 8 interfaces and 8 routes.
Web Interface
To configure an IP configuration in the web interface:
1. Click System, IP Address, Advanced IP Settings.
2. Click Add Interface and then configure the new Interface for the switch.
3. Click Add Route and then configure the new route for the switch.
4. Click Apply.
Figure 3-2.1: The Advanced IP Settings page
Parameter descriptions:
Advanced IP Settings
DNS Server: Controls the DNS name resolution done by the switch. These modes are supported:
No DNS server: No DNS server will be used.
Configured: Explicitly provide the IP address of the DNS Server in dotted decimal notation.
From this DHCP interface: Specify from which DHCP-enabled interface a provided DNS server
should be preferred.
From any DHCP interfaces: The first DNS server offered from a DHCP lease to a DHCP-enabled
interface will be used.
IP Interfaces
Delete: Select this option to delete an existing IP interface.
VLAN: The VLAN associated with the IP interface. Only ports in this VLAN will be able to access the IP
interface. This field is only available for input when creating a new interface.
DHCPv4 Enabled: Enable the IPv4 DHCP client by checking this box. If this option is enabled, the
system will configure the IPv4 address and mask of the interface using the DHCP protocol. The DHCP
client will announce the configured System Name as hostname to provide DNS lookup.

DHCPv4 Fallback: The number of seconds for trying to obtain a DHCP lease. After this Timeout period
expires, a configured IPv4 address will be used as IPv4 interface address. A value of zero disables the
fallback mechanism, such that DHCP will keep retrying until a valid lease is obtained. Legal values are 0
to 4294967295 seconds.
DHCPv4 Current Lease: For IPv4 DHCP interfaces with an active lease, this column show the current
interface address, as provided by the DHCP server.
IPv4 Address: The IPv4 address of the interface in dotted decimal notation.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation on the
interface is not desired.
IPv4 Mask: The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and 30
bits for an IPv4 address.
If DHCP is enabled, this field is not used. The field may also be left blank if IPv4 operation on the
interface is not desired.
IPv6 Address: The IPv6 address of the interface. An IPv6 address is in 128-bit records represented as
eight fields of up to four hexadecimal digits with a colon separating each field (:). For example,
fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that can be used as a shorthand way of
representing multiple 16-bit groups of contiguous zeros; but it can appear only once. It can also
represent a legally valid IPv4 address. For example, ::192.1.2.34.
The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask: The IPv6 network mask, in number of bits (prefix length). Valid values are between 1 and
128 bits for an IPv6 address.
The field may be left blank if IPv6 operation on the interface is not desired.
IP Routes
Delete: Select this option to delete an existing IP route.
Network: The destination IP network or host address of this route. Valid format is dotted decimal
notation or a valid IPv6 notation. A default route can use the value 0.0.0.0or IPv6 :: notation.
Mask Length: The destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values are between
0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a mask length of 0 (as it will
match anything).
Gateway: The IP address of the IP gateway. Valid format is dotted decimal notation or a valid IPv6
notation. Gateway and Network must be of the same type.
Next Hop VLAN (Only for IPv6): The VLAN ID (VID) of the specific IPv6 interface associated with the
gateway. The given VID ranges from 1 to 4094 and will be effective only when the corresponding IPv6
interface is valid.
If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway.
If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the gateway.
Buttons
Add Interface: Click to add a new IP interface. A maximum of 8 interfaces is supported.
Add Route: Click to add a new IP route. A maximum of 8 routes is supported.
Apply: Click to save changes.
Reset: Click to undo any changes made locally and revert to previously saved values.
