Secure Shell (SSH) Protocol and SNMPv3 protect information from tampering or eavesdropping by encrypting information being passed along the network, thereby guarding administrative information. These features are available only on the enhanced image.

With the Cisco Catalyst 2955, network managers can implement high levels of console security. Multilevel access security on the switch console and the Web-based management interface prevent unauthorized users from accessing or altering switch configuration. TACACS+ and RADIUS authentication enable centralized access control of the switch and restrict unauthorized users from altering the configuration. Deploying security can be done through Cisco Cluster Management Suite (CMS) Software Security Wizards, which ease the deployment of security features that restrict user access to a server, a portion of the network, or the entire network.

Q. Do Cisco Catalyst 2955 switches support switch clustering?

A.Yes. Cisco Catalyst 2955 switches can be managed using Cisco CMS Software, which uses Cisco switch clustering technology. Cisco CMS is Web-based software that is embedded in Cisco Catalyst 3550, 2955, 2950, 2950ST-LRE, 3500 XL, 2900 XL, 2900 LRE XL, and 1900 switches. Through Cisco switch clustering technology, users can access Cisco CMS with any standard Web browser to manage up to 16 of these switches at once, regardless of their physical proximity—with the option of using a single IP address if desired.

Cisco CMS provides an integrated management interface for Cisco Catalyst 2955 switches to deliver intelligent services such as multilayer switching, QoS, multicast, and security access control lists (ACLs). Cisco CMS allows administrators to take advantage of benefits formerly reserved for only the most advanced networks—without having to learn the command-line interface (CLI) or even the details of the technology. The new Cisco CMS Guide Mode leads the user step-by-step through the configuration of high-end features and provides enhanced online help for context-sensitive assistance. In addition, wizards provide automated switch configuration to optimally support video streaming or videoconferencing, voice over IP (VoIP), and mission-critical applications. Wizards for LAN security and multicast are also provided.

Cisco CMS supports standards-based connectivity options such as Ethernet, Fast Ethernet, Fast EtherChannel, Gigabit Ethernet, and Gigabit EtherChannel connectivity. Because Cisco switch clustering technology is not limited to a single stack of switches, Cisco CMS expands the traditional cluster domain beyond a single wiring closet, saving time and effort for network administrators.

Cisco Catalyst 2955 Series switches can be configured either as command or member switches in a Cisco switch cluster. Cisco CMS also allows the network administrator to designate a standby or redundant command switch, which takes the commander duties if the primary command switch fails. Other key features include the ability to simultaneously configure multiple ports and switches, perform software updates across the entire cluster at once, and clone configurations to other clustered switches for rapid network deployments. Bandwidth graphs and link reports provide useful diagnostic information, and the topology map gives network administrators a quick view of the network status.

Q. Does the Cisco Catalyst 2955 Series support Inter-Switch Link (ISL) trunking?

A. No. The Cisco Catalyst 2955 Series hardware does not support ISL trunking. For customers with a requirement to deploy ISL trunking, Cisco Catalyst 3550 switches support both ISL and 802.1Q trunks.

2955 specifications

The Cisco Systems 2955 series, a robust family of integrated services routers, symbolizes versatility and reliability for businesses in need of scalable networking solutions. Designed to provide a seamless connection for enterprise branches, the 2955 series is engineered for superior performance, security, and low operational costs, making it an ideal choice for businesses aiming for efficiency.

One of the standout features of the Cisco 2955 is its modular design, which allows for the customization of WAN and LAN interfaces. This flexibility enables enterprises to adapt their networking capabilities as their requirements evolve. The router supports a variety of interface types, including Serial, T1/E1, and EtherSwitch, providing solutions for diverse applications and ensuring compatibility with a wide range of network deployments.

A key technology incorporated into the 2955 is Cisco IOS Software, which delivers advanced routing, switching, and security features. This operating system is foundational for managing network traffic efficiently and ensures high availability, security, and performance. The router also supports Voice over IP (VoIP) applications, facilitating improved communication across the enterprise by enabling businesses to combine voice and data traffic over a single network.

Security is paramount in modern networking, and the Cisco 2955 series does not disappoint. Integrated security features, such as VPN support, firewall capabilities, and intrusion prevention, provide a comprehensive approach to protecting enterprise networks from threats. The router also supports secure access methods, ensuring that only authorized users can connect to the network.

In addition, the Cisco 2955 is designed with enhanced management features. The integration of tools for network monitoring and troubleshooting simplifies the management of complex network environments, enabling IT teams to maintain optimal performance and quickly resolve issues.

With support for Power over Ethernet (PoE), the 2955 can power connected devices directly through the Ethernet cables, reducing the need for separate power sources and simplifying deployment for devices like IP phones and wireless access points. This capability enhances the overall efficiency of network infrastructure while contributing to a reduction in operational costs.

In summary, the Cisco Systems 2955 series stands out as a powerful and flexible router solution for enterprises seeking reliability and advanced features. With its modular design, integrated security, and support for various network technologies, the 2955 enables organizations to build robust and scalable networks that can adapt to the evolving demands of their operations.
