Technical Specifications
DES-1526
PoE 10/100Mbps Smart Switch
Product Features
Quality of Service Support
Port Mirroring
The DES-1526 provides Layer 2 802.1p control for prioritized
network packet transmission. Classification of network data
priorities can be based on Priority Queues. This QoS support
allows you to run bandwidth-intensive and delay-sensitive
applications, and is of particular importance to IP phone and
Internet server cameras attached to your network.
The DES-1526 supports port mirroring to assist network
traffic monitoring. Your network administrator can use this
function as a diagnostic tool or debugging feature, especially
when fending off an attack. It enables you to keep close track
of switch performance and alter it, if necessary. Port mirroring
can be managed locally or remotely. Your administrator places
a protocol analyzer on the port receiving the mirrored data to
monitor each segment separately. The analyzer captures and
evaluates the data without affecting the client on the original
port.
Easy Management
The DES-1526 is designed as an affordable solution for
business to implement security, QoS and power sourcing
without having to go through complex SNMP network
management. All functions can be configured for the switch
from any network station via an Internet browser, dispensing
you of the need to set up consoles and connect console
cables.
