» Include IP-MAC-port binding user

access screening, traffic segmentation,

802.1Q VLANs, 802.1X port-based/

MAC-based access control, external

RADIUS server authentication support.

» 802.1D Spanning Tree/802.1w Rapid

Spanning Tree, STP loopback detection

and broadcast storm control for network

resilience.

» 802.3ad Link Aggregation port trunks for

switch cascading and server link.

(for DES-3028, 3028P, 3052, 3052P only)

» Up to 256 profiles, 256 rules for

individual switch ports or range of ports.

» ACL rules can be based on switch port,

VLAN ID, 802.1p Priority Queues, MAC

address, IPv4 address, DSCP, protocol

type, TCP/UDP port, user-defined

packet content and time-based ACL.

» Fine granularity to define limits down to

64Kbps segments for each port.

» When applied to control of broadcast

storms infected with virus, can limit

level of damage a virus attack can do to

network.

» IGMP snooping to control multicast

transmission.

» Port mirroring to facilitate diagnostics.

» Network administrators can pre-set

configurations and save them in TFTP

server.

» Individual switches can boot their

IP from server and load in pre-set

configurations.

» Multiple switch units can be managed

as a single object (a virtual stack), all

units identified by a single IP address.

» Network administrators can see Tree

View of members of the virtual stack

and network topology showing locations

of the units and their link information.

These managed Layer 2 Ethernet switches provide an entry-level SNMP

management solution for businesses. Workgroups looking for an advanced yet

affordable solution can deploy these switches to bring managed Ethernet connection

to their desktops.

These switches include more advanced software features than similar devices of

the same class. These features allow administrators to set up a secure network and

fine-tune the workgroup performance. For inter-workgroup connection, the switches

provide fiber uplinks to connect together groups of users in, for example, different

classrooms or departments spread across on a campus or between buildings.

Supporting D-Link’s Single IP Management, these switches can be easily configured

with any switches supporting D-Link’s Single IP Management, including the xStack

core switches, for integration with a more comprehensive network structured with

backbone and centralized high-speed servers.
