DGS-1100/ME Metro Ethernet Managed Switch CLI Reference Guide

INTRODUCTION
The DGS-1100-16/ME consists of 16-ports 10/100/1000Mbps.
The DGS-1100-18/ME consists of 16-ports 10/100/1000Mbps ports + 2-ports 1000Mbps SFP
The DGS-1100-24/ME consists of 24-ports 10/100/1000Mbps.
The DGS-1100-24P/ME consists of 12-ports 10/100/1000Mbps PoE + 12-ports 10/100/1000Mbps.
The DGS-1100-26/ME consists of 24-ports 10/100/1000Mbps + 2-ports 1000Mbps SFP.
The Switch can be managed through the Telnet management agent. The Command Line Interface (CLI)
can be used to configure and manage the Switch via the Telnet interfaces.
This manual provides a reference for all of the commands contained in the CLI. Configuration and
management of the Switch via the Telnet interfaces is discussed in the Manual. For detailed information
on installing hardware please refer also to the Manual.
Setting the Switch’s IP Address
Each Switch must be assigned its own IP address, which is used for communication with an SNMP
network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP
address is 10.90.90.90. You can change the default Switch IP address to meet the specification of your
networking address scheme.
The Switch is also assigned a unique MAC address by the factory.
The Switch’s MAC address can also be found in the Telnet interfaces by entering show switch.
The IP address for the Switch must be set before it can be managed with the Telnet interfaces. The Switch IP
address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned
to the Switch must be known.
Alternatively, users can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP
address to be assigned to the IP interface named System and the z represents the corresponding number of
subnets in CIDR notation.
The IP interface named System on the Switch can be assigned an IP address and subnet mask which
can then be used to connect a management station to the Switch’s Telnet management agent.
Figure 1–1 Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.90.90.91 with a subnet mask of
255.0.0.0. The system message Success indicates that the command was executed successfully. The
Switch can now be configured and managed via Telnet, SNMP MIB browser and the CLI using the above
IP address to connect to the Switch.

PRODUCT INTRODUCTION
Thank you and congratulations on your purchase of D-Link DGS-1100/ME Series Switch Products.
D-Link's next generation DGS-1100 Series switches blend plug-and-play simplicity with exceptional
value and reliability for small and medium-sized business (SMB) networking. All models are housed in a
new style rack-mount metal case with easy-to-view front panel diagnostic LEDs.
The brand-new DGS-1100/ME series are green by design with IEEE 802.3az Energy Efficient Ethernet
compliant (abbreviated as EEE) and D-Link Green Technologies. This allows significant power saving
during periods of low data activity. In most environments, switches are idle 90% or more of the time. If
there has been no network traffic over a short period of time, ports on DGS-1100 switch will change to
power saving mode automatically. Once a packet is received, the switch wakes and works immediately,
returning to normal funcationality. By using EEE compliant devices, such as PCs and servers, the
network can save energy without compromising any performance. Even when connecting to legacy
devices which do not support IEEE 802.3az, D-Link Green Technologies can reduce power consumption
by changing the power state of the link.

Step 2: Switch Installation
For safe switch installation and operation, it is recommended that you:
•Visually inspect the power cord to see that it is secured fully to the AC power connector.
•Make sure that there is proper heat dissipation and adequate ventilation around the switch.
•Do not place heavy objects on the switch.
Desktop or Shelf Installation
When installing the switch on a desktop or shelf, the rubber feet included with the device must be attached on
the bottom, at each corner of the device’s base. Allow enough ventilation space between the device and the
objects around it.

Rack Installation
The switch can be mounted in an EIA standard size 11-inch rack, which can be placed in a wiring closet with
other equipment. To install, attach the mounting brackets to the switch’s side panels (one on each side) and
secure them with the screws provided (please note that these brackets are not designed for palm size switches).
Figure 3-2 – Attach the mounting brackets to the Switch
Then, use the screws provided with the equipment rack to mount the switch in the rack.
Figure 3-3 – Mount the Switch in the rack or chassis
Please be aware of following safety Instructions when installing:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room temperature. Therefore, consideration should be
given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required
for safe operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g. use of power
strips)."

Step 3 – Plugging in the AC Power Cord
Users may now connect the AC power cord into the rear of the switch and to an electrical outlet (preferably one
that is grounded and surge protected).
Figure 3-4 – Plugging the switch into an outlet
Power Failure
As a precaution, the switch should be unplugged in case of power failure. When power is resumed, plug the
switch back in.
Grounding the Switch
This section describes how to connect the DGS-1100/ME Series Switch to ground. You must complete this
procedure before powering your switch.
Required Tools and Equipment
•Ground screws (included in the accessory kit): One M4 x 6 mm (metric) pan-head screw
•Ground cable (not included in the accessory kit): The grounding cable should be sized according to local and
national installation requirements. Depending on the power supply and system, a 12 to 6 AWG copper conductor
is required for U.S installation. Commercially available 6 AWG wire is recommended. The length of the cable
depends on the proximity of the switch to proper grounding facilities.
•A screwdriver (not included in the accessory kit)
The following steps let you connect the switch to a protective ground:
Step 1: Verify if the system power is off.
Step 2: Use the ground cable to place the #8 terminal lug ring on top of the ground-screw opening, as seen in
the figure below.
Step 3: Insert the ground screw into the ground-screw opening.
Step 4: Using a screwdriver, tighten the ground screw to secure the ground cable to the switch.
Step 5: Attach the terminal lug ring at the other end of the grounding cable to an appropriate grounding stud or
bolt on rack where the switch is installed.
Step 6: Verify if the connections at the ground connector on the switch and the rack are securely attached.

USING THE COMMAND LINE INTERFACE
The Switch allows a computer or terminal to perform some basic monitoring and configuration tasks by
using the Command Line Interface (CLI) via TELNET protocol.
NOTE: Switch configuration settings are saved to non-volatile RAM using the save command.
The current configuration will then be retained in the Switch’s NV-RAM, and reloaded when the
Switch is rebooted. If the Switch is rebooted without using the save command, the last
configuration saved to NV-RAM is loaded.
The command line functions are accessed over a Telnet interface. Once an IP address for the Switch has
been set, A Telnet program can be used (in VT-100 compatible terminal mode) to access and control the
Switch.
After the Switch reboots and you have to logged in, the console looks like this:
Figure 5–1 Initial Console Screen after Logging In
Commands are entered at the command prompt, DGS-1100-24P/ME:admin#
There are a number of helpful features included in the CLI. Entering the ? command displays a list of all
of the top-level commands.
