SuperStack II Switch
Layer 3 Module
The SuperStack II Switch Layer 3
module lets you cost effectively add
routing capabilities to your switched
10/100/1000 Mbps workgroups to boost
intranet performance and off-load legacy
routers of LAN traffic. SuperStack II
Switch 1100, 3300, and 3300 FX
switches with the easy-to-install Layer 3
module seamlessly route IP traffic
between subnets. IPX, AppleTalk, and
other legacy protocols will be switched
within their subnet (VLAN). One
SuperStack II Layer 3 module can
manage routing for the entire stack.
■ Extensive standards-based routing pro-
tocol support (including RIP and
OSPF) enables the switches to operate
in any networking environment.
■ Distance Vector Multicast Routing
Protocol (DVMRP) optimizes multi-
media traffic delivery.

ATM Expansion Module
The SuperStack II Switch 1100/3300
ATM expansion module provides one
high-speed ATM port for connection to
a high-speed ATM backbone. The port
is software-configurable to run at either
OC-3c (155 Mbps) or OC-12c (622
Mbps) speeds, so you can run at OC-3c
speeds today and upgrade to higher
OC-12c capability in the future with no
additional hardware investment. The
SuperStack II Switch 1100/3300 ATM
expansion module delivers cost-effective
functionality and performance.
Advanced, built-in ATM switching and
Ethernet-to-ATM internetworking fea-
tures include 802.1Q Ethernet VLANs
to ATM-based ELANs mapping, and
Ethernet 802.1p (amendment to
802.1D) prioritization traffic to ATM
Quality of Service mapping. When
SuperStack II Switch 1100, 3300, or
3300 FX are configured in a stack, mul-
tiple expansion modules can provide
resiliency and load sharing across all
ATM ports.
■ The expansion module’s innovative
software-configurable OC-3c/OC-
12c ATM port accommodates future
backbone bandwidth needs without
additional hardware or software.
■ The module supports industrywide
ATM standards, including UNI
3.0/3.1, and 4.0 signaling and
LAN Emulation (LANE) 1.0
and 2.0 for interoperability in
ATM environments.
