Features & Benefits:
- Port-based and IEEE802.1Q Tagged VLAN (4K PVID)
- Intrusion lock, MAC Freeze, MAC filtering &
Static MAC Forwarding for L1/L2 Security Protection
- 802.1x for Access Authentication and Management
over VLAN and Bandwidth per Valid User's Attribute
- MVR Ensure Valid Transmission of Multicasting
Stream on the Network-wide Multicast VLAN
- iStacking™ Clustering Technology, One IP Management
for 24 Devices
- iManage™ Easy Management Tools (GUI, CLI & Text-based
Configuration for Scripting)
Best fit for SMB & Campus for Convergence Network
- ZyXEL ES-2048 is an entry-level, managed L2 Fast
Ethernet Switch, and specially designed for SMB or Campus
to empower multi-tasks in today's dynamic network environment
requiring capability over security, QoS and network
management. Complete product portfolio with optimized
port configuration (26/50 port), embedded two dual-personality
GbE ports and Power over Ethernet (PoE) can easily find
solution and fit in any network very easily.
High-Security Network Edge - The ES-2048 features
wide range security functions to prevent unauthorized
data access. 256 Static VLAN entry enables complicated
VLANs portfolio for policy management. Full range 4K
VLAN (4K PVID) are equipped as well. Besides central
access authentication by 802.1x, it can further assigns
VLAN and bandwidth per pre-defined attribute for valid
user which greatly lifts flexibility over network management.
In addition, extra support of MAC filtering, MAC freezing
and Specific MAC forwarding, allow the network administrator
to set security policy toward device MAC address. The
ES-2048 is designed to offer comprehensive security
features for enforcing security policies to the edge.
Intelligent Traffic Prioritization for Multi-Services
- Multiple priority queues and scheduling mechanism,
makes the ES-2048 easy to perform traffic prioritizing
for delay-service applications. You can also customize
DSCP settings to provide an end-to-end QoS environment.
MVR ensures efficient transmission of multicasting stream
on the network-wide multicast VLAN. For bandwidth management,
the ES-2048 supports bandwidth increment of 64Kbps to
give different bandwidth allocations. Moreover, with
broadcast storm control, network can limit the broadcast
packets once over pre-defined threshold which prevents
the network outrage.
Industry Standard-based Network Management -
Managing the ES-2048 is simple through its iStacking™,
SNMP, Web, telnet and RS-232 support. iStackingTM, ZyXEL-exclusive
clustering technology, allows administrators to manage
up to 24 switches with one single IP. In addition, IT
staff may opt for Web, CLI (Command Line Interface)
or text-based configuration for their convenience and
even encrypt the instructions using SSHv1/v2 and SSL.
Thanks to these sophisticated functionalities, the IT
staff is able to build a highly secure and efficient
corporate network with minimum effort.
Installment Freedom by Power over Ethernet
- The ES-2048 supports IEEE802.3af Power over Ethernet
(PoE) to ease the installment in challenging space,
such as ceiling or top of wall, Device compliant with
IEEE802.3af, like WLAN AP, IP surveillance camera, etc,
can get powered Ethernet connectivity through just single
Cat-5 cable, with up to 100 meters of successful link
distance. There is no need to use extra power adapter
and you can walk away from the headache of how to set
up the power line to devices. In addition, ES-2048 supports
intelligent power management via web GUI. You can set
the priority levels of power-feeding over different
ports to get the best use of power resource.
