Multiple priority queues and scheduling mechanism make the ZyXEL 2000 Series easy to perform 

traffic prioritizing for delay-service applications, and you can also customize DSCP settings to 

provide an end-to-end QoS environment. The MVR ensures efficient transmission of multicasting 

stream on the network-wide multicast VLAN. For bandwidth management, the 2000 Series supports 

bandwidth increments to give different bandwidth allocations. With broadcast storm control, the 

network keeps the broadcast packets below the pre-defined threshold to prevent network outrages.

The ZyXEL 2000 Series features wide-range security functions to prevent unauthorized data access. 

The 256 Static VLAN entry enables complicated VLANs portfolio for policy management, and the full-

range 4K VLAN (4K PVID) is equipped as well. In addition to 802.1x central access authentication, it 

further assigns VLAN and bandwidth per pre-defined attribution for valid users to add flexibility to 

network management. In addition, extra support of MAC filtering, MAC freezing and Specific MAC 

forwarding allow network administrators to set security policies toward the device MAC addresses. 

The 2000 Series has been designed to offer comprehensive security features for enforcing security 

policies to the edge.

The ZyXEL 2000 Series comes with rich management tools to streamline your management effort. 

With ZyXEL’s exclusive iStacking™ technology, you can manage up to 24 ZyXEL switches through 

one IP address. In addition, through Web-GUI, CLI (Command Line Interface) and text-based 

configuration, network managers can select the one management interface they are most 

comfortable with to get the job done efficiently. Moreover, you can protect your management 

session with SSHv1/v2 authentication and SSL encryption features. With the comprehensive 

features, ZyXEL’s 2000 Series is your first choice for cost-effective networking.
