SuperStack II Switch 1100 and SuperStack II Switch 3300 Optional High-Speed Accessories (continued)
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.

SuperStack II Switch 1100/3300 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.
