Affordable, Managed Gigabit Switching with Flexible Uplinks
The "smart" voice-ready 3Com® Baseline Plus Switch 2952 is a web-managed Gigabit switch with extensive layer 2 functionality and layer 3 static routes. It offers enterprise-class features, customized and priced for small- and mid-sized organizations.
With an easy-to-use switch interface and advanced features (VLANs, IEEE 802.1X authentication and QoS), this switch is the most cost-effective way to provide a converged network.
Layer 2 Switching with Advanced Features
The Baseline Plus Switch 2952 has forty-eight 10/100/1000 Mbps ports and four 1000 Mbps SFP ports (fiber) to connect to high-performance computers, servers, or core network backbones.
This "smart" switch has the features that help build a voice ready network, with support for auto-voice VLAN, LLDP, SNMP-based management, IGMP snooping, and IEEE 802.1X and advanced Access Control Lists (ACLs) for strengthening security.
The switch provides non-blocking performance— all 52 ports perform at wirespeed which helps to eliminate network traffic bottlenecks. LACP link aggregation (IEEE 802.3ad) allows ports to be automatically grouped together to form an ultra-high-bandwidth connection that greatly expands bandwidth capacity to the network backbone.
The Baseline Plus Switch 2952 also supports Spanning Tree, Rapid Spanning Tree and Multiple Spanning Tree, traffic prioritization, priority queuing and VLANs. These switching features ensure optimal use of available bandwidth as traffic flow is directed according to the needs of the business.
No Switch Setup Required
This Baseline Plus switch is operational straight out-of-the-box; as long as default settings are acceptable, there is no need to configure the switch. If desired, the switch can be configured using a web browser or SNMP management software.
Enhanced Intuituve Management Options
For networks that require more control, the switch web management interface provides an intuitive, menu driven process for even novice users to quickly and confidently configure the switch during initial setup and manage it during normal operation. Graphical switch and port views provide a clear understanding of switch status and configuration.
In addition, the web interface features individual port-traffic monitoring (port mirroring) and MAC address port mapping tables. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web management interface further simplifying network installation.
With single IP management, up to 32 devices of the same family (3CRBSGxxx models) can be managed from one IP address via the IRF Lite functionalit.
This Baseline Plus Switch is also supported by IMC (Intelligent Managent Center), 3Com Network Supervisor (3NS) and 3Com Network Director (3ND) management software.
IMC can be used to map the network topology, indicating what devices are connected, and on what ports. Switch management and software upgrades can be easily done. Other SNMP-based management tools may also be used.
The Switch family also supports a compact Command Line Interface (CLI) that is accessed via the front panel console port. Using the CLI, initial switch setup options can be quickly configured.
