Lenovo CE0128TB Gigabit Ethernet Campus Switch

Product Guide (withdrawn product)

The Lenovo CE0128TB Switch is a 1/10 Gb Ethernet (GbE) switch that delivers a compact, high-density,

cost-effective GbE solution for 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 campus networks. It can also be used as a management network switch in the data center

infrastructures.

The CE0128TB switch offers 24x 10/100/1000BASE-T (RJ-45) fixed ports and 4x SFP+ ports that support

1 GbE and 10 GbE optical transceivers, 10 GbE active optical cables (AOCs), and 10 GbE direct attach

copper (DAC) cables. The switch supports a wide range of L2 and L3 features that provide performance,

availability, security, and manageability for campus networks.

Key features

The CE0128TB switch is considered particularly suited for the following environments:

Economical network connectivity for 1 GbE access layer deployments in branch and remote offices, as

well as enterprise campus networks.

1 GbE management network connectivity in data center infrastructures.

1 GbE network connectivity with 10 GbE SFP+ ports for additional server, storage, or switch

connections.

Virtualized and cloud environments with multiple 1 GbE ports.

Scalable 1 GbE networking deployments with switch stacking.

Converged infrastructures with 1 GbE NAS or iSCSI.

The CE0128TB switch offers the following features and benefits:

High performance

The 1/10 GbE CE0128TB switch provides a combination of low latency and non-blocking, line-rate

switching.

Availability and redundancy

The CE0128TB switch offers learns alternate routes automatically and performs faster convergence in

case of a link or switch failure.

Layer 3 functionality

In addition to Layer 2 switching, the CE0128TB switch includes Layer 3 functionality, which provides

security and performance benefits of inter-VLAN routing with support for static routes and dynamic

routing protocols, including Routing Information Protocol (RIP) and Open Shortest Path First (OSPF).

Quality of Service

The CE0128TB 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 CE0128TB 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).

Stacking

The CE0128TB supports stacking of up to eight campus switches (including intermix of CE0128TB,

CE0128PB, CE0152TB, and CE0152PB switches), enabling simplified, centralized management of a

single logical entity that uses a single switch image, configuration file, management IP address, and

management interface.

Simplified management

To ease deployment, the CE0128TB 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.

AutoInstall

The CE1028TB switch supports the AutoInstall feature, which enables upgrading the switch software

image and installing configuration files via TFTP automatically during the boot process by using the

resources available on the network.
