The ZyXEL ES3500-24 has been specially designed for small- and medium-scale businesses
(SMB) to deliver valuable Ethernet services. With the high-performance hardware platform,
businesses can easily extend network topologies while enabling robust security, QoS and
management functions to help customers fulfilling different needs and to support the IPv6
for trouble-free future network expansions.
Benefits
Advanced QoS for significant services
Consistent service quality and reliable connecting ability in a converged network is the key for SMB
to connect and satisfy customers; therefore the ability to control traffic flow and set traffic policy
becomes more critical than ever. The ZyXEL ES3500-24 24-port FE L2 Switch offers wire-speed flow
control that classifies and prioritizes the incoming packets according to the predefine QoS policies
that meet requirements of SMB.
In terms of classification, the Differentiated Services Code Point (DSCP) field and the 802.1p Class of
Service (CoS) field are identified to assess the priority of incoming packets. Classification and
reclassification can be based on criteria as specific as rules based on IP, MAC addresses, VLAN ID or
TCP/UDP port number. For bandwidth management, the ES3500-24 provides 8 priority queues per
port for different types of traffics, allowing SMB to set policy-based rate limitations that take full
advantage of constrained network resources and guarantee the best performance.
Enhanced security for protection among customers
Avoiding subscribers affecting each other on a shared network or shared device is a major concern
for SMB. The ZyXEL ES3500-24 offers a complete set of security features to protect user data while
administrating the traffics. Port security provides the ability to deny unauthorized users from
accessing the network. Moreover, the 802.1X feature cooperating with RADIUS is useful to prevent
unauthorized access based on username and password (or other credentials) and acts as powerful
access control for converged networks with mixed wired and wireless access.
The ES3500-24 provides a multilayer (L2/L3/L4) ACL suite of sophisticated policy-based control
mechanisms that enables SMB to deploy easily based on actual network environment needs via a
Web GUI or command line interface to prevent abnormal or illegal access. The policies can be
defined to deny packets based on source and destination MAC addresses, IP addresses or TCP/UDP
ports.
