Catalyst

2955 Series Switches are industrial-grade switching products that

provide wire-speed Fast Ethernet and Gigabit Ethernet connectivity for deployment in

harsh environments. The Cisco Catalyst 2955 Series operates in environments such as

industrial networking solutions (industrial Ethernet deployments), intelligent transportation

systems (ITS), and transportation network solutions. It integrates into military equipment,

Supervisory Control and Data Acquisition (SCADA) systems, power generation systems,

waste water treatment facilities, building automation systems, warehouses, and any other

facilities or applications where the environmental conditions or suspended solid

concentrations exceed the specifications of other commercial switching products.

The Cisco Catalyst 2955 Series uses industrial-grade components, a compact form

factor, convection cooling, and relay output signaling to extend intelligent services such

as enhanced security, high availability, and advanced quality of service (QoS) to areas

that cannot be served by traditional commercial-grade Ethernet switches.

Embedded in all Cisco Catalyst 2955 Series Switches is the Cisco Device Manager software,

which allows users to easily configure and monitor the switch using a standard Web browser,

eliminating the need for more complex terminal emulation programs and knowledge of the

command-line interface (CLI). Customers can easily initialize the switch with Web-based Cisco

Express Setup, without using the CLI. In addition, with Cisco Network Assistant, a standalone

network management application, customers can simultaneously configure and troubleshoot

multiple Cisco Catalyst desktop switches. Cisco Device Manager, Cisco Express Setup, and

Cisco Network Assistant reduce the cost of deployment by enabling less-skilled personnel to

set up switches quickly. Furthermore, Cisco Catalyst 2955 Series Switches provide extensive

management tools using Simple Network Management Protocol (SNMP) network management

platforms such as CiscoWorks.

This product line offers Cisco IOS

Software functionality for traditional data, video, and voice

services, with enhanced intelligent services features for additional security, advanced QoS, and

high availability. Intelligent services are critical in supporting the reliability and determinism of

proprietary Layer 2 solutions typical of industrial Ethernet deployments, while providing the

advantages (standardization, open connectivity, bandwidth, integration, etc.) of an advanced

Ethernet switching architecture. These intelligent services include Layers 2-4 traffic prioritization,

rate limiting, and security filtering, helping to ensure the high uptime, low latency, deterministic

performance, and data integrity critical for industrial automation control networks.

Cisco Catalyst 2955 Series Switches consist of the following devices:

●

Cisco Catalyst 2955T-12—Twelve 10/100 ports and two fixed 10/100/1000BASE-T uplink

ports

●

Cisco Catalyst 2955C-12—Twelve 10/100 ports and two fixed 100BASE-FX multimode

uplink ports

Data Sheet ● Cisco Catalyst 2955S-12—Twelve 10/100 ports and two fixed 100BASE-LX single-mode uplink ports Intelligence in the New Ethernet Networks Currently, non-Ethernet Layer 2 networks are evolving from traditional field buses or proprietary technologies to standards-based Ethernet networks.

Data Sheet Secure Shell (SSH) Protocol and SNMPv3 protect information from tampering or eavesdropping by encrypting information being passed along the network, thereby guarding administrative information. Private VLAN Edge isolates ports on a switch, helping ensure that traffic travels directly from the entry point to the aggregation device through a virtual path and cannot be directed to another port.
PAGE 4
Data Sheet After the packet goes through classification, policing, and marking, it is assigned to the appropriate queue before exiting the switch. Cisco Catalyst 2955 Series Switches support four egress (outgoing port) queues per port, allowing the network administrator to be more discriminating and specific in assigning priorities for the various applications on the network. At the egress level, the switch performs scheduling—an algorithm that determines the order in which the queues are processed.

Data Sheet Network Management Customers can configure one switch at a time with the embedded Cisco Device Manager or configure and troubleshoot multiple switches with Cisco Network Assistant, a standalone network management software application optimized for LANs of small and medium-sized businesses with up to 250 users. Cisco Device Manager offers a simple and intuitive GUI interface for configuring and monitoring the switch.

Data Sheet Enhanced Hardware Features The Cisco Catalyst 2955 Switch has been designed for deployment in harsh environments. Through the use of special thermal design techniques and industrial-rated components, the Cisco Catalyst 2955 is rated to operate at extreme temperatures (-40° to 60° C; -40° to 140° F). Robust mechanical specifications allow for its deployment as a mobile platform and under extreme vibration and shock environments (50G trapezoidal shock pulse).

Data Sheet Feature Benefit instance per VLAN, enabling Layer 2 load sharing on redundant links. ● VLAN Trunking Protocol (VTP) pruning limits bandwidth consumption on VTP trunks by flooding broadcast traffic only on trunk links required to reach the destination devices. Dynamic Trunking Protocol (DTP) enables dynamic trunk configuration across all ports on the switch.
PAGE 8
Data Sheet Feature Benefit ● Trusted Boundary provides the ability to trust the QoS priority settings if a Cisco IP phone is present and to disable the trust setting if the IP phone is removed, preventing a rogue user from overriding prioritization policies in the network. ● IGMP Filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
PAGE 9
Data Sheet Feature Benefit Management Superior manageability ● An embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis. ● The switch supports all nine RMON groups through the use of a Cisco SwitchProbe® Analyzer Switched Port Analyzer (SPAN) port, permitting traffic monitoring of a single port, a group of ports, or the entire switch from a single network analyzer or RMON probe.
PAGE 10
Data Sheet Feature Benefit Support for CiscoWorks ● Manageable through CiscoWorks network management software on a perport and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs. ● SNMPv1, v2, and v3 (non-crypto) and Telnet interface support deliver comprehensive in-band management, and a CLI-based management console provides detailed out-of-band management.
