Introduction
The Lenovo CE0152TB 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 CE0152TB switch offers 48x 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.

Did you know?
The CE0152TB switch supports the GARP VLAN Registration Protocol (GVRP) protocol for simplifying and automating VLAN configuration.

The CE0152TB switch supports stacking, enabling up to eight interconnected switch devices to be managed as a single logical device.

The CE0152TB switch supports AutoInstall, which enables a switch to automatically configure itself using the resources available on the network, without manual intervention.

The CE0152TB switch offers the following features and benefits:

High performance
The 1/10 GbE CE0152TB switch provides a combination of low latency and non-blocking, line-rate switching.

Availability and redundancy
The CE0152TB 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 CE0152TB 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 CE0152TB 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 CE0152TB 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 CE0152TB 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 CE0152TB 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 CE1052TB 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.
