SuperStack II Switch 9300
The SuperStack II Switch 9300 enables
practical, cost-effective, and high-
performance deployment of Gigabit
Ethernet as an effective interswitch,
switch-to-server, and general purpose
backbone technology. As the highest den-
sity Gigabit Ethernet (1000/1000 Mbps)
switch available in a SuperStack II
package, the SuperStack II Switch 9300
delivers full line-rate switching between
its 12 Gigabit Ethernet ports to support
17.85 million pps forwarding rate and
12 Gbps full-duplex throughput. Mul-
tiple Gigabit Ethernet ports can
be trunked together to deliver up to
6 Gbps interswitch link. Full line-rate
Gigabit Ethernet switching is supported
on all ports via 25.6 Gbps switching
fabric.
The SuperStack II Switch 9300 is
available in three versions: a fixed
12-port fiber optic (12 x 1000BASE-SX)
Gigabit Ethernet switch; a fixed 12-port
fiber optic (10 x 1000BASE-SX and 2 x
1000BASE-LX) Gigabit Ethernet switch;
and a fixed 12-port fiber optic (12 x
1000BASE-LX) Gigabit Ethernet switch.
With the SuperStack II Switch 9300,
you can interconnect high densities of
Fast Ethernet switches that are attached
to either dedicated desktops or shared
segments and high-bandwidth network
resources, such as servers.
Key features include:
■ Supports up to 16,000 MAC
addresses
■ Multicast filtering using IGMP
snooping
■ Multicast throttling limits broadcasts
and multicasts on a per-port basis
■ Support for IEEE 802.3x flow
control on all full-duplex ports
■ Roving Analysis Port (RAP) for
copying data from any port to another
port with a network analyzer attached
■ RMON support for four groups
■ Fully standards-based 802.1Q
VLANs, including GVRP support
for automatic VLAN configuration
distribution
■ IEEE 802.1D (incorporating 802.1p)
Class of Service support and dual pri-
ority queuing
■ Web browser interface for manage-
ment and configuration functions
■ Resilient links
