We received two network switches from D-Link, a managed and an unmanaged one.
Let’s dwell on their features and analyze their performance based on the
benchmark results.

This is a 24 port 10/100 Mbps Fast Ethernet Managed Layer 2 Switch. As you would
expect from a managed network device, the switch is easy to configure through a
Web based interface. It supports all Standard L2 features such as VLANs, Link
Aggregation, IGMP Snooping, Spanning Tree, etc.

In its security features, the switch provides traffic control and
segmentation, port security, trusted hosts, etc. It also comes with some QoS
features such as IEEE 802.1P port default priority, IEEE 802.1P user priority,
etc. Port Bandwidth is another useful feature in QoS, which provides control on
transmitting and receiving data rates for any selected port.

Price and Warranty:

DGS-1024D: Rs 15,000 (1 yr); DES-3026: Rs 23,000 (1 yr)

Meant For:

Managed switch for SMBs and unmanaged for data centers

Key Specs:

Managed switch is Fast Ethernet and supports QoS, VLAN, link aggregation, etc, while unmanaged is 24-port, Gbe, with auto-negotiation and flow control


Managed switch is easy to configure, good management software

The product also ships with D-View SNMP network management software. This
software has useful tools that allow you to effectively manage device
configurations, fault tolerance, and security. For non-D-Link switches, it has
an MIB compiler to compile MIB files of the third party device into a
system-recognized format.

We stressed the switch with NetIQ Qcheck. It gave an average throughput of 94
Mbps and a maximum throughput of ’96 Mbps’ in an isolated network while
transferring 1000 Kbytes of payload from one end to another and in a response
time of 1ms. Overall, the switch is very easy to use and configure.

This one is a plug n play 24-port unmanaged Layer 2 Gigabit Ethernet Switch. It
supports IEEE 802.3 Ethernet, 802.3u Fast Ethernet, 802.3x Flow Control and
802.3ab Gigabit Ethernet standards. According to D-Link, it has a MAC Address
table size of 8K to facilitate scalability. The larger the MAC address table
size the larger the number of networks that the switch can support.

According to D-Link, this switch provides flow control for full-duplex mode,
and back pressure flow control for half-duplex mode which eases traffic
congestion and ensures reliable data transmission. The back-pressure flow
control allows loss-free transmission by having gateways verify that the next
gateway has sufficient buffer space available before sending data.

It also has Auto-Negotiation on its each port, which senses the link speed of
a network device connected (either 10, 100 or 1000 Mbps) and ensures
compatibility of the port’s speed with that of the network device.

Its each port supports a cable diagnostic feature which informs the user
about cable related problems through LED’s. However, this feature is only
available at Switch Bootup.

This switch was again tested using NetIQ’s Qcheck. It gave an average
throughput of 728 Mbps on transferring 1000 Kbytes of payload from one end to
another, which is pretty much similar to the other Gigabit switches we have
tested in the past.

Bottom Line: Considering its performance and features, DGS-1024D
switch is ideal for briskly adding Gigabit Ethernet LAN functionality to your
servers, network backbone connections, etc, even though the price is a little
high. The managed DES-3026 switch has customizable features and its performance
and price make it worth a buy.
