Ultra Flexible and Scalable Switch

Clustering Technology

• GigaStack™ GBIC delivers a hardware-based,

independent stacking bus with up to 2 Gbps

forwarding rate in a point-to-point conﬁguration, or

1 Gbps forwarding bandwidth when daisy chained

with up to 9 switches

• Clustering now supports the member discovery and

cluster creation over a single routed hop

• Cisco Switch Clustering technology allows the user to

manage up to 16 inter-connected Catalyst 3550-12T,

Catalyst 2950, Catalyst 3500 XL, Catalyst 2900 XL

and Catalyst 1900 switches through a single IP address

without the limitation of being physically located in

the same wiring closet

• GBIC-based Gigabit Ethernet ports give customers

a choice of 1000BaseSX, 1000BaseLX/LH,

1000BaseZX, 1000BaseT or Cisco GigaStack

stacking GBICs to ﬁt their connection needs

• Command switch redundancy allows customers to

designate a backup command switch that takes over

cluster management functions in the event of a failure

of the primary command switch

• Easy interfaces to complex tasks of setting up

Layer 3 functions

Integrated Cisco IOS Switching Solution

• Cisco Group Management Protocol (CGMP) server

functionality enables a switch to serve as the CGMP

router for CGMP client switches and IGMP snooping

is supported in the hardware

• Bandwidth aggregation up to 16 Gbps through

Gigabit EtherChannel

enhances fault tolerance and

offers higher-speed aggregated bandwidth between

switches, to routers and individual servers

• Per-port broadcast, multicast, and unicast storm

control prevents faulty end stations from degrading

overall systems performance

• IOS Command Line Interface (CLI) support provides

common user interface and command set with all

Cisco routers and Cisco desktop switches

• Cisco Discovery Protocol (CDP) enables a CiscoWorks

network management station to automatically

discover the switch in a network topology

• VLAN trunks can be created from any port using

either standards-based 802.1Q tagging or the Cisco

ISL VLAN architecture

• Support for 1005 VLANs per switch and 128

instances of Spanning Tree per switch

• Cisco Virtual Trunking Protocol (VTP) supports

dynamic VLANs and dynamic trunk conﬁguration

across all switches

• Dynamic Trunking Protocol (DTP) enables dynamic

trunk conﬁguration across all ports in the switch

• Port Aggregation Protocol (PAgP) automates the

creation of Fast EtherChannel or Gigabit

EtherChannel groups, enabling linking to

another switch, router, or server.

• Support for Maximum Transmission Units (MTUs)

of up to 2025 Bytes

Superior Manageability

• Built-in Web-based Cisco CMS software provides an

easy-to-use Web-based management interface through

a standard browser such as Netscape Navigator or

Microsoft Internet Explorer

• SNMP and Telnet interface support delivers

comprehensive in-band management, and a

Command Line Interface (CLI)-based management

console provides detailed out-of-band management

• Manageable through CiscoWorks Windows network

management software on a per-port and per-switch

basis providing a common management interface for

Cisco routers, switches and hubs

• Supported by the Cisco Quality Policy Manger (QPM)

solution

• 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

SwitchProbe

Analyzer (SPAN) port which permits

trafﬁc monitoring of a single port, a group of ports, or

the entire switch from a single network analyzer or

RMON probe
