• IEEE 802.3z-compliant 1000BaseSX, 1000BaseLX/LH, and

1000BaseZX physical interface support through a

ﬁeld-replaceable GBIC module provides customers

unprecedented ﬂexibility in switch deployment

• Autosensing on each port detects attached device speed and

automatically conﬁgures the port for 10- or 100-Mbps

operation, easing the deployment of the switch in mixed

10BaseT and 100BaseTX environments

• Autonegotiating on all ports automatically selects half- or

full-duplex transmission mode to optimize bandwidth

• Autoconﬁguration eases switch deployment in the network by

automatically conﬁguring multiple switches across a network

via a boot server

• Default conﬁguration stored in Flash memory ensures that a

switch can be quickly connected to the network and can pass

trafﬁc with minimal user intervention, preserving conﬁguration

in case of a power outage

Integrated Cisco IOS Switching Solution

• Cisco Group Management Protocol (CGMP) enables a switch

to selectively and dynamically forward routed IP multicast

trafﬁc to targeted multimedia end stations, reducing overall

network trafﬁc

• CGMP Fast Leave allows end stations to quickly exit from a

multicast session, reducing superﬂuous network trafﬁc

• Virtual LAN trunks can be created from any port using either

standards-based 802.1Q tagging or the Cisco ISL VLAN

architecture

• IEEE 802.1p Layer 2 protocol for prioritization of mission

critical and time sensitive trafﬁc from data, voice, and telephony

applications

• Cisco Virtual Trunking Protocol (VTP) supports dynamic

VLANs and trunk conﬁguration across all switches

• Cisco IOS Command-line interface (CLI) support provides

common user interface and command set across all Catalyst

series switches and Cisco routers

• Cisco Discovery Protocol (CDP) enables a CiscoWorks

network management station to automatically discover a switch

in a network topology

Superior Manageability

• Built-in Web-based management interface provides easy-to-use

management through a standard browser such as Netscape

Navigator or Microsoft Explorer

• Simple Network Management Protocol (SNMP) and Telnet

interface support deliver comprehensive in-band management,

and a CLI-based management console provides detailed

out-of-band management

• Manageable through CiscoWorks2000 network management

software on a per-port and per-switch basis, providing a

common management interface for Cisco routers, switches, and

hubs

• 8 MB DRAM and 4 MB Flash memory onboard, enabling the

addition of a continuous stream of feature upgrades and

maximizing customer investments

• Conﬁgurable network port, supporting unlimited MAC

addresses for backbone connectivity

• Embedded Remote Monitoring (RMON) software agent

supports four RMON groups (History, Statistics, Alarms, and

Events) for enhanced trafﬁc management, monitoring, and

analysis

• Support for all nine RMON groups through use of a switch port

analyzer (SPAN) 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

• Domain Name System (DNS) client support provides IP

address resolution with user-deﬁned device names

• Trivial File Transfer Protocol (TFTP) reduces the cost of

administering software upgrades by downloading from a

centralized location

• Network Time Protocol (NTP) provides an accurate and

consistent timestamp to all switches within the intranet

• Multifunction LEDs per port for port status, half-duplex/

full-duplex, and 10BaseT/100BaseTX indication, as well as

switch-level status LEDs for system, redundant power supply

(RPS), and bandwidth utilization provide a comprehensive and

convenient visual management system

Security and Redundancy

• Cisco Uplink Fast technology ensures quick failover recovery,

enhancing overall network stability and reliability

• Support for TACACS+ authentication enables centralized

control of the switch and restricts unauthorized users from

altering the conﬁguration

• MAC-based port-level security prevents unauthorized stations

from accessing the switch

• User-selectable address learning mode simpliﬁes conﬁguration

and enhances security

• Multilevel security on console access prevents unauthorized

users from altering switch conﬁgurations
