Lenovo CE0128T Switch (Gigabit Ethernet)

Product Guide

The Lenovo CE0128T Switch is a 1 Gb Ethernet (GbE) switch that delivers a compact, high-density, cost-

effective GbE solution for small network environments where space and power are at a premium. Featuring

a small, 1U footprint, this switch is designed for access-layer deployments in branches, retail and

workgroup environments, and network access in larger networks.

The CE0128T Switch offers 24x 10/100/1000BASE-T ports for server, storage, and network connectivity

and 4x 1 GbE SFP uplink ports for connections to higher-layer devices.

The CE0128T Switch supports a wide range of L2 and L3 features that provide performance, availability,

security, and manageability for campus networks.

The Lenovo CE0128T Switch is shown in the following figure.

Key features

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.
