Dimension ES-4024
Managed 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.
