The CE0128T Switch is designed to deliver non-blocking, line-rate throughput.

The CE0128T Switch supports the GARP VLAN Registration Protocol (GVRP) protocol for simplifying and automating VLAN configuration.

The CE0128T Switch supports stacking, enabling up to eight interconnected CE0128T Switch devices to be managed as a single logical device.

The CE1028T Switch supports Zero Touch Provisioning, which enables a switch to automatically provision itself using the resources available on the network, without manual intervention.

The CE0128T Switch is considered particularly suited for the following customers:

• Customer who need economical network connectivity solution for access layer deployments in branch and remote offices, as well as enterprise campus networks.
• Customers who want to use GbE in their infrastructure (servers and networking).
• Customers who are implementing a virtualized environment and require multiple GbE ports.
• Customers who want to reduce total cost of ownership (TCO) and improve performance while maintaining high levels of availability and security.
• Customers who want to implement a converged infrastructure with NAS or iSCSI.

The CE0128T Switch offers the following key features and benefits:

• High performance

  The CE0128T Switch provides a combination of non-blocking line-rate GbE switching with as low as 4 microseconds latency and 256 Gbps switching capacity.

• Layer 3 functionality

  In addition to Layer 2 switching, the CE0128T Switch includes Layer 3 functionality, which provides security and performance benefits of inter-VLAN routing with support for static routes.

• Quality of Service

  The CE0128T Switch supports traffic classification and processing to provide consistent network performance and efficient use of network bandwidth by allocating and scheduling resources based on service levels requirements for different data streams.

• Security

  Working as an enforcement point, the CE0128T Switch provides standards-based 802.1x port-level access control for multiple devices per port, as well as Layer 2-4 policy enforcement with Access Control Lists (ACLs).

• Simplified management

  To ease deployment, the CE0128T Switch supports the industry-standard Link Layer Discovery Protocol (LLDP) and GARP VLAN Registration Protocol (GVRP) protocols, enabling the switches to automatically discover Ethernet-enabled devices and automate VLAN configuration.

• Stacking

  The CE0128T Switch supports stacking, enabling up to eight interconnected CE0128T Switch devices to be managed as a single logical device, delivering a scalable, pay-as-you-grow solution for expanding network environments.

• Zero Touch Provisioning

  The CE1028T supports CPE WAN Management Protocol (CWMP) for zero-touch provisioning (ZTP). ZTP enables a switch to automatically provision itself using the resources available on the network, without manual intervention. ZTP automatically handles the process of upgrading the switch software image and installing configuration files.
