Table 1: New Hardware Features

Hardware Feature	Description	Where Documented
Catalyst 5509 chassis	Provides support for the following: Supervisor Engines II and III Supports up to eight  additional switching modules (Ethernet, Fast Ethernet, Gigabit Ethernet, CDDI/FDDI, ATM, and Token Ring) Supports the RSM and RSM/VIP2 modules Supports redundant supervisor engines (Supervisor Engines II and III); redundancy is supported only with like supervisor engines	Quick Installation Guide ---Catalyst 5509 Catalyst 5000 Series Installation Guide
9-port Gigabit EtherChannel Switching Module (Base unit, WS-X5410) 1000BaseSX GBIC (WS-G5484) 1000BaseLX GBIC (WS-G5485) 1000BaseLH GBIC (WS-G5486)	Provides nine Gigabit Ethernet ports that you can configure with any combination of shortwave (SX), longwave (LX), and long-haul (LH) Gigabit Interface Carriers (GBICs). The module has a 3.6-Gbps connection to the Catalyst 5000 series switch backplane.	Catalyst 5000 Series Gigabit EtherChannel Switching Module Installation and Configuration  Note
48-port 10BaseT Ethernet Module (WS-X5012A)	Provides 48-switched, 10-Mbps (10BaseT Category  3 UTP), full- or half-duplex Ethernet port connections using four telco RJ-21 connectors (12  interfaces per connector).

Table 2 summarizes the new and modified software features for Catalyst 5000 series software release 4.2, and tells you where they are documented.

Table 2: New Software Features

Software Feature	Description	Where Documented
Multiprotocol over ATM (MPOA)	Enables the fast routing of internetwork-layer packets across a nonbroadcast, multiaccess (NBMA) network. MPOA replaces multihop routing with point-to-point routing using a direct virtual channel connection (VCC) between ingress and egress edge devices or hosts.	Catalyst 5000 Series Software Configuration Guide: "Configuring Multiprotocol Over ATM" chapter Catalyst 5000 Series Command Reference
Dynamic Trunking Protocol (DTP)	DTP negotiates with its neighbor port and synchronizes port configuration to be an ISL trunk port or 802.1Q trunk port or an access (non-trunk) port.
