ZyXEL ES-3024 Layer 2 Stackable Switch 160212.3024 ユーザーズマニュアル

The ES-3024 is a managed stackable layer 2 switch for workgroups or WAN edge applications. It is equipped with twenty-four 

10/100Mbps ports and two expansion slots that accommodate optional 10/100/1000Base-T, 1000Base-SX or GBIC modules. 

With the recent growth of Gigabit Ethernet in Metropolitan Area Networks (MAN), expansion modules provide unparalleled 

flexibility for supporting a wide variety of uplink infrastructures while maintaining a competitive price to performance ratio. 

The IEEE 802 standard-based firmware provides a rich set of features and ensures interoperability with equipment from other 

vendors. Additionally, the firmware includes advanced features such as IGMP snooping, broadcast storm control, and MAC 

address filtering, to enhance security and bandwidth utilization.

With its built-in web-based management, the ES-3024 offers an easy-to-use, platform-independent management and 

configuration facility. The ES-3024 supports standard Simple Network Management Protocol (SNMP) and can be managed via 

any standard-based management software. For text-based management, the ES-3024 can also be accessed via Telnet and the 

console port.

The ES-3024 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. 

The clustering design enables system administrators to 

configure and manage up to 8 units of the ES-3024 through a 

single IP address. This enables service providers to start with a 

minimal initial investment and add more equipment as 

customers increase. Network expansion can be accomplished 

without increasing management efforts. 

The VLAN feature in the ES-3024 offers the benefits of both 

security and performance. VLAN is used to isolate traffic 

between different users and thus provides better security. 

Limiting the broadcast traffic to within the same VLAN 

broadcast domain also enhances performance.

In order to fulfill the needs 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, allowing service providers to offer tiered service. 

Port mirroring copies traffic from a specific port to a target 

port. This mechanism helps track network errors or abnormal 

packet transmission without interrupting the flow of data. 

The IGMP snooping feature forwards traffic only to subscribers 

that request the multicast traffic. This prevents unnecessary 

forwarding of multicast traffic to all subscribers, therefore 

optimizing bandwidth utilization for bandwidth-consuming 

applications such as broadcast video. 

The broadcast storm control gives system administrators the 

choice to either forward or discard broadcast packets created 

by malicious or run-away applications. This prevents 

unnecessary waste of bandwidth to enhance bandwidth 

utilization. 

The ES-3024 supports not only 802.1x port-based access 

control for subscriber authentication, but 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, highly enhances network security. The ES-

3024 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.
