anaged Layer 3 Switch
The ES-4024 Ethernet switch brings a high level of security and traffic control to your network. With wire-speed Layer 2 and Layer
3 switching capability and resilient routing protocols, the ES-4024 enables hardware-based, IP layer network management that
reduces backbone traffic and enhances performance of the overall network. 24 fast Ethernet ports, two GBIC uplink slots and an
optional dual Gigabit stacking module provide resilient workgroup connectivity.
In addition to providing security, the ES-4024 is also capable of offering Quality of Service (QoS). The Layer 2 to Layer 3 filtering
and IEEE 802.1x based authentication prevent unauthorized users from illegally accessing the network, while intelligent features
such as DiffServ, Layer 4 wire-speed traffic classfier, and bandwidth limiting and multicasting ensure optimal network performance.
The IEEE 802 standard-based firmware provides a rich set of features and ensures interoperability with equipment from other
vendors. The firmware includes advanced features such as IGMP snooping, broadcast storm control, and MAC address filtering,
all of which enhance security and bandwidth utilization.
With its built-in web-based management, the ES-4024 offers an easy-to-use, platform-independent management and
configuration facility. The ES-4024 supports standard Simple Network Management Protocol (SNMP) and can be managed via
any standard-based management software. For text-based management, the ES-4024 can also be accessed via Telnet and through
the console port.
Wire-speed Layer 2 to Layer 3 Switching
The ES-4024 supports MAC and IP switching in wire speed.
Up to 12.8Gbps non-blocking switching capability provides
high performance network tasks.
IP Routing and Service
The ES-4024 supports multiple IP domains, static routing,
RIP v1/v2 and OSPF routing protocol, thus reducing backbone
traffic and increasing IP switching efficiency. The ES-4024
supports DHCP server and relay.
Port Trunking Provides Higher Availability
The ES-4024 supports IEEE 802.3ad with load distribution
control and fail-over recovery. With the exception of
expansion slots, up to 8 ports can be aggregated for bandwidth
up to 1600Mbps. No matter what modules are used for
expansion slots, all traffic is aggregated based on MAC
addresses, thus balancing the traffic load.
Clustering Simplifies Network Configuration and Management
A cluster design enables system administrators to configure
and manage up to 8 units of the ES-4024 through a single IP
address. This enables service providers to start with a minimal
initial investment and add more equipments as customers
increase. Network expansion may be accomplished without
increasing management efforts.
VLAN Offers Both Security and Performance
The VLAN feature in the ES-4024 offers the benefits of both
security and performance. VLAN, which is used to isolate
traffic between different users provides better privacy and thus
better security. Limiting broadcast traffic to within the same
VLAN broadcast domain also enhances performance.
Rate Limitation Allows Service Differentiation
In order to fulfill the requirements of different customers,
service providers need a network infrastructure that combines
guaranteed performance and flexibility in service provisioning.
Rate adaptation on subscriber ports allows increments of
1Kbps, enabling service providers to offer tiered service.
Access Control Enhances Network Security
The ES-4024 not only supports 802.1x port-based access
control for subscriber authentication, it also allows system
administrators to define a limited number of MAC addresses
that can access the network from a particular port.
This feature, which denies unauthorized devices from
communicating through the switch, greatly enhancing network
security. The ES-4024 also supports the ability to limit the
number of users (MAC addresses) that can simultaneously
access the network on a per-port basis, allowing service
providers to offer flexible billing plans.
