Benefits:
Robust and Highly Available System Design - ZyXEL ES-3148
is a high-density L2+ managed switch with 48 10/100Mbps RJ-45 ports,
two GbE copper ports and two dual-personality SFP/copper GbE interface.
Coupled with the advanced ASIC hardware and switching capacity of
17Gbps, the ES-3148 is an ideal platform to power premium triple-play
applications. What makes the ES-3148 unique is its robust and highly
available system design. The support of 802.3ad Link aggregation
reduces network downtime by providing more packet paths and bandwidth
aggregation to critical paths. In case a link is down, IEEE 802.1w
RSTP allows the ES-3148 to quickly recover from failed links and
send packets through a backup link. The 4G uplink not only gives
superb transmission bandwidth, but also allows you to set up Gigabit
aggregation. In addition, BPS is also available for feeding in extra
DC back-up power to prepare for any unexpected power failure. All
these great features and more in the ES-3148 give you the network
performance you need with minimum downtime.
Intelligent QoS for Multi-Service Optimization - In today's
changing networking and business environment, one of the keys to
success is in how corporations harness new applications (such as
VoIP and video conferencing) for work efficiency. To take advantage
of these applications, the ability to manage traffic is extremely
important to fully utilize your network bandwidth. The ES-3148 is
equipped with L2+ multi-layer ACL (L2~L4) for QoS, 8 hardware priority
queues, DSCP and WFQ scheduling algorithm. These bandwidth guaranteeing
and priority optimizing features maximize bandwidth usage and provide
premium quality network service.Furthermore, to optimize IP Multicasting
applications, IGMP snooping also get supported. For flexible bandwidth
control, the ES-3148 allows you to limit bandwidth usage to the
granularity of 64Kbps.
Complete, Multi-Layer Protection - The multi-layer ACL
(L2~L4) protection on the ES-3148 shield against potential network
threats. You can create security settings by setting (L2 ~L4) ACL
parameters (such as MAC, VLAN, IP, Protocol type,TCP/UDP port and
DSCP). You can also create up to 4K VLANs to implement different
security policies. For user access control, the ES-3148 supports
port-based IEEE 802.1x user authentication from a centralized RADIUS
server. Foe device access control, you can configure MAC freeze,
MAC filtering and limit the number of MAC address learned on a port.
The ES-3148 also comes with the intrusion lock feature designed
to prevent unauthorized access. In addition, the ES-3148 is capable
of providing enterprise-class L2 VPN with VLAN Stacking (Q in Q)
to enhance security protection. Thus, the ES-3148 allows you to
implement a strict layer1 to layer4 security protection.
Convenient, Hassle-free Network Management - With a number
of management methods (iStacking™, SNMP, Web, telnet and the console
port), the ZyXEL's exclusive iStacking™ technology allows you to
manage a switch cluster (of up to 24 ZyXEL switches) through a single
master ZyXEL switch. This significantly reduces operation cost and
provides the flexibility of maintaining multiple ZyXEL switches.
In addition, network administrators can choose to manage the switch
using the friendly web-based configuration or the convenient text-based
CLI (Command Line Interface.). In addition, SSHv1/v2 and SSL gives
encrypted management sessions. Thanks to these sophisticated features,
network administrators can set up powerful corporate networks and
streamline their management efforts.
