2. Web-based Switch Configuration
Management Options
Logging into the Web UI
Web User Interface (Web UI)
Management Options
The Switch provides multiple access platforms that can be used to configure, manage, and monitor networking
features available on this Switch. Currently there are three management platforms available, which are described
below.
Command Line Interface (CLI)
The Switch can be managed, out-of-band, by using the console port or the MGMT port on the front panel of the
Switch. Alternatively, the Switch can also be managed, in-band, by using a Telnet connection to any of the LAN ports
on the Switch. The command line interface provides complete access to all Switch management features.
Refer to the DGS-3630 Series CLI Reference Guide for more detailed information about the CLI.
SNMP-based Management
The Switch can be managed with an SNMP-compatible Network Management System (NMS). The Switch supports
SNMP v1/v2c/v3. The SNMP agent on the Switch decodes the incoming SNMP messages and responds to requests
with MIB objects stored in the database. The SNMP agent on the Switch updates the MIB objects to generate
statistics and counters.
Web User Interface (Web UI)
The Web UI can be accessed from any computer running web browsing software from its MGMT port or LAN port
when it is connected to any of the RJ45 or SFP/SFP+ ports. The Web UI on the Switch can also be accessed using an
HTTPS (SSL) connection.
This management interface is a graphical representation of the features that can be viewed and configured on the
Switch. Most of the features available through the CLI can be accessed through the Web UI. Web browsers like
Microsoft Internet Explorer, Mozilla Firefox, or Google Chrome can be used.
NOTE: The OpenFlow feature and all settings related to the feature, can only be enabled and
configured through the CLI. Refer to the DGS-3630 Series Command Line Interface (CLI)
Guide (OpenFlow) for more information.
NOTE: The CLI provides the functionality of managing, configuring, and monitoring all of the
software features that are available on the Switch.

Parameter Description
The Master setting will allow the port to advertise capabilities related to duplex,
speed and physical layer type. The master setting will also determine the
master and slave relationship between the two connected physical layers. This
relationship is necessary for establishing the timing control between the two
physical layers. The timing control is set on a master physical layer by a local
source.
The Slave setting uses loop timing, where the timing comes from a data stream
received from the master. If one connection is set for master, the other side of
the connection must be set for slave. Any other configuration will result in a ‘link
down’ status for both ports.
Options to choose from are:
•Auto - Specifies that for copper ports, auto-negotiation will start to
negotiate the speed and flow control with its link partner. For fiber ports,
auto-negotiation will start to negotiate the clock and flow control with its
link partner.
•10M - Specifies to force the port speed to 10 Mbps. This option is only
available for 10 Mbps copper connections.
•100M - Specifies to force the port speed to 100 Mbps. This option is only
available for 100 Mbps copper connections.
•1000M - Specifies to force the port speed to 1 Gbps. This option is only
available for 1 Gbps fiber connections.
•1000M Master - Specifies to force the port speed to 1 Gbps and operates
as the master, to facilitate the timing of transmit and receive operations.
This option is only available for 1 Gbps copper connections.
•1000M Slave - Specifies to force the port speed to 1 Gbps and operates
as the slave, to facilitate the timing of transmit and receive operations. This
option is only available for 1 Gbps copper connections.
•10G - Specifies to force the port speed to 10 Gbps. This option is only
available for 10 Gbps fiber connections.
•10G Master - Specifies to force the port speed to 10 Gbps and operates
as the master, to facilitate the timing of transmit and receive operations.
This option is only available for 10 Gbps copper connections.
•10G Slave - Specifies to force the port speed to 10 Gbps and operates as
the slave, to facilitate the timing of transmit and receive operations. This
option is only available for 10 Gbps copper connections.
