ZyXEL es-4024a ユーザーズマニュアル

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.

The ES-4024 supports MAC and IP switching in wire speed. 

Up to 12.8Gbps non-blocking switching capability provides 

high performance network tasks.

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.

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. 

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. 

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.

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. 

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.
