• 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
