Powerful
Full 12, 24 or 48 10/100/1000 ports and a
non-blocking design provide wire speed
throughput and maximum bandwidth for the most
demanding network environments. Small
Form-factor Pluggable (SFP) modules deliver
choice in 1000Base-SX, 1000Base-LX or
1000Base-ZX (70Km) optics. The Layer 2
management features optimize bandwidth
throughout the network ¡V delivering Gigabit
performance to systems, applications, and
services. Take advantage of forwarding rates up
to 71.4 million pps, and a switching capacity of
96 Gbps.
Easy to Use
Move up to Gigabit power in minutes. Use any of
these solutions as a managed switch out of the
box ¡V just plug and play! All ports are
auto-negotiating and support Auto Uplink™
technology. Choose from two easy-to-use
management interface options ¡VWeb interface or a
command line interface available through console
or Telnet. Comprehensive remote administration
capabilities reduce the need for on-site
administration. Easy to troubleshoot ¡V built-in
testing capability locates cable related network
problems.
Manageable
Meet your management needs with SNMP (v1, v2c
and v3), RMON, Command-Line Interface (CLI) and
complete Web-based GUI. Advanced features
include up to 512 VLANs, DiffServ traffic
prioritization and 802.1p (QoS) for Voice over
IP services (VoIP), broadcast storm protection,
RADIUS, 802.1x, port trunking, rapid spanning
tree, and link aggregation. Full Layer 2
implementation allows you to configure your
network for maximum performance, reliability,
and availability. Manageable with any popular
SNMP-based management software, but optimized
for NETGEAR
ProSafe Network Management Software NMS100.
