ZyXEL ES-4124 is a 24-port premium L3+ managed switch. Besides, comprehensive L2+ features and 

resilient hardware design, advanced routing like RIP, OSPF, VRRP, IGMP and DVMRP are supported to fully 

shoulder the tough tasks in the network core. For service providers, public sectors, healthcare industry, and 

SMB, the ES-4124 is the ideal solution to build up a convergence network empowering high network 

resiliency, superior QoS and strict security protection.

The ES-4124 supports VRRP routing protocol for failover transmissions. BPS, second DC power source, 

protects from internal AC power supply failure. IEEE802.3ad Link aggregation reduces network downtime 

by providing more packet paths and bandwidth aggregation to critical paths. The 4G uplink not only gives 

superb transmission bandwidth, but also allows users to set up Gigabit aggregation to secure critical path 

transmission. IEEE802.1w Rapid spanning tree (RSTP) allows immediate recovery from failed links by 

sending packets via a backup link path.

The ES-4124 comes with comprehensive features sets for QoS, like DVMRP, multi-layer aware ACL 

(L2/L3/L4), 8 hardware priority queues, DSCP and WFQ scheduling algorithm, etc to easily harness IP 

applications, like VoIP, Video streaming, video-conferencing and IP TV. In addition, the ES-4124 supports 

flexible bandwidth control with granularity of 64kbps that enables network operators to perform efficient 

bandwidth administration.

Multi-layer aware ACL (Access Control List) enforces policy-based protection by utilizing parameters (MAC, 

VLAN, IP, Protocol, TCP/UDP, and DSCP). To fine-tune device access control levels, you can configure MAC 

freeze, MAC filtering and limit the number of MAC address on a port. To complement user authentication, 

802.1x can further facilitate the assignment of VLAN and bandwidth. “Intrusion lock” can down the link 

once link status change. In addition, VLAN Stacking (Q-in-Q) can be applied for enterprise-class L2VPN 

application. All the features above allow users to implement strict layer 1 to layer 4 security policies.
