The NS4802 can be programmed for advanced switch management function, such as dynamic port link aggregation, Q-in-Q
VLAN, Multiple spanning tree protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD snooping. The NS4802
allows the operation of a high-speed trunk combining multiple ports. It enables up to 3 groups of 6 ports for trunk maximum and
supports connection fail-over as well.
Powerful Security
The NS4802-24P-4S-2X offers comprehensive layer2 to layer4 access control list (ACL) for enforcing security to the edge. It
can be used to restrict to network access by denying packets based on source and destination IP address, TCP/UDP port
number or defined typical network applications. Its protection mechanism also comprises 802.1x Port-based and MAC-based
user and device authentication. With the private VLAN function, communication between edge ports can be prevented to
ensure user privacy.
Enhanced Security and Traffic Control
The NS4802-24P-4S-2X also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent
IP snooping from attack and discard ARP packets with invalid MAC address. The network administrator can now construct
highly secured corporate networks with considerably less time and effort than before.
User-friendly Secure Management
For efficient management, the NS4802-24P-4S-2X managed switch is equipped with console, web and SNMP management
interfaces. With the built-in web-based management interface, the NS4802-24P-4S-2X offers an easy-to-use, platform
independent management and configuration facility. The NS4802-24P-4S-2X supports SNMP and it can be managed via any
management software based on standard of SNMP v1 and v2 protocol. For reducing product learning time, the
NS4802-24P-4S-2X offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new command
from these switches. Moreover, the NS4802-24P-4S-2X offers remote secure management by supporting SSH, SSL and
SNMPv3 connection which can be encrypted the packet content at each session.
Flexible and Extendable Solution
The 4 mini-GBIC SFP slots built in the NS4802-24P-4S-2X support dual speed as it features 100BASE-FX and
1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber-optic modules. Now the administrator can flexibly choose the
suitable SFP transceiver according to not only the transmission distance, but also the transmission speed required. The
distance can be extended from 550 meters to 2km (multi-mode fiber) and up to above 10/20/30/40/50/70 kilometers
(single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
Intelligent SFP Diagnosis Mechanism
The NS4802 supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily
monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature,
laser bias current, and transceiver supply voltage.
