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-2024PWR 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-2024PWR 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.
