Cisco Product Catalog, February 1999
Security and Redundancy
IEEE 802.1d Spanning-Tree Protocol support for redundant backbone connections and loop-free  networks simplifies
network configuration and improves fault tolerance
User-selectable address learning mode simplifies configuration and enhances security
Support for optional Cisco 600 watt redundant AC power system provides a backup power source for up to four units for
improved fault tolerance and network uptime
Flexible Network Configuration
No per-port Media Access Control (MAC) address limitations--provides flexibility to connect to individual users or
shared hubs. Support for 1024 MAC addresses on the Catalyst 1900 allows the switch to scale with a growing network
Configurable network port that supports unlimited MAC addresses for backbone connectivity
Management
Simple Network Management Protocol (SNMP) and Telnet support delivers comprehensive in-band manageability, and
a menu-based management console provides in-depth, out-of-band manageability
Supports 4 groups of embedded RMON (history, statistics, alarms, and events). Support for all nine RMON groups
through use of a SwitchProbe Analyzer port that permits traffic monitoring of a single port, a group of ports, or the entire
switch from a single network analyzer or RMON probe (Enterprosed Edition only).
Web-based secured interface allows users to configure and manage the switch from any client on the Internet with a web-
browser.
Cisco Discovery Protocol (CDP) enables a CiscoWorks network management station to automatically discover the switch
in a network topology
Autonegotiation on 100BaseTX ports automatically selects half- or full-duplex transmission mode to optimize bandwidth
