OVERVIEW
The "smart" voice-ready 3Com
®
Baseline Plus Switch
2920 delivers Layer 2 enterprise-class Gigabit
switching solutions along with layer 3 static routes,
customized and priced for small and mid-sized
organizations.
These managed switches offer tremendous value to
small and medium businesses looking for a low cost
solution who need a level of control over their network
not offered by unmanaged switching products, without
sacrificing the advanced functionality normally found
on higher-end managed switching products.
KEY BENEFITS
LAYER 2 SWITCHING WITH ADVANCED FEATURES
The Baseline Plus Switch 2920 helps build a voice
ready network—with 3Com’s unique auto-voice VLAN,
advanced voice QoS, SNMP-based management and
other features.
To ensure optimal use of the network bandwidth and
deliver maximum voice and data quality, traffic flow
can be directed according to the needs of the business
using Spanning Tree and Rapid Spanning Tree, traffic
prioritization, priority queuing and VLANs.
Link aggregation can be done via IEEE 802.3ad LACP
or manually, allowing ports to be grouped together to
form an ultra-high-bandwidth connection that greatly
expands bandwidth capacity to the network core or
other parts of the network.
ENTERPRISE-QUALITY SECURITY
Enterprise-quality security is provided with IEEE
802.1X network login and advanced Access Control
Lists (ACLs), which enable usage policies via the
switch at each point of access to the network. Time
based policies can also be configured on these
switches. All management communications are
encrypted with HTTPS.
NO SWITCH SETUP REQUIRED
Baseline Plus switches are 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,
console port, or SNMP management software.
ENHANCED INTUITIVE 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.
