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.
