Feature Function Benefit
dynamic port-based VLAN
configuration as per IEEE
802.1Q.
provides dynamic VLAN
configurations and reduces
administrative tasks associated
with static VLANs.
802.1p Priority Utilizes separate transmission
queues for low and high priority
traffic.
Helps ensure low-latency
delivery of time critical network
traffic, e.g., traffic associated
with voice or video
communication.
Quality of Service (QoS) Prioritizes traffic based upon
user-defined criteria, including
L2, L3 and L4 information.
Helps ensure time-critical
network traffic is delivered as
per network administrator’s
prioritization needs. Helps
expedite traffic based upon L2,
L3 or L4 information, such as
IP ToS, and provides greater
control over traffic flow within
the network.
Link Aggregation (802.3ad) Groups up to seven ports
together into a single, high-
bandwidth trunk. LACP provides
automatic detection of link
aggregation groups.
Helps increase bandwidth for
critical network links (e.g.,
uplinks to a network backbone)
and creates link redundancy.
LACP provides easy to deploy
and resilient link aggregation
groups.
Multicast Support Detects ports that are
participating in IP Multicast
communication, e.g.,
multimedia streams.
Limits broadcast traffic to those
ports that are actually
participating in the
communication.
Spanning Tree Support Automatically configures ports
for speed, duplex mode, flow
control and cabling used. Rapid
spanning tree improves the time
to reconfigure the topology as
compared to standard spanning
tree.
Helps reduce network set-up
time and improves network
availability by automatically
activating standby links when
current link goes down.
Management Enables remote configuration
and monitoring of the switch via
a Web-browser or a SNMP-
based management console
application. Industry standard
CLI provides command line
interface for switch
configuration.
Allows a network administrator
to detect and remedy problems
at local and remote locations.
Industry standard CLI
leverages network
administrator’s knowledge of
industry-standard CLI and
provide a common platform for
switch configurations.
Authentication Support SSL provides encryption of
management traffic when
accessing the switch via the
embedded web server. SSH
Helps enhance the security of
the network by encrypting
network management traffic.
