More Information of this Item

The WS-C2955T-12 Cisco Catalyst 2955T 12-port switch is a managed Layer 4 switch, meaning it can perform advanced routing and traffic management based on Layer 4 (transport layer) information such as port and protocol. It has 12 Fast Ethernet ports, which supports 100Mbps of data transfer rate. It is rack-mountable, making it suitable for installation in a standard equipment rack.

The switch can be managed through a web interface or the command-line interface (CLI) using Cisco's proprietary iOS software. It provides a wide range of features for network management, security, and reliability. It supports wire-speed performance and has redundant power supplies for added protection against power failures. Additionally, it has a feature called Cisco StackWise technology that allows multiple switches to be connected together and managed as a single entity, providing redundancy and failover in case of a switch failure.

The switch also includes security features such as Access Control Lists (ACLs) and IEEE 802.1x authentication to protect against unauthorized access and malicious activity.

Performance and Reliability

The WS-C2955T-12 Cisco Catalyst 2955T 12-port switch is designed to deliver high performance and reliability in enterprise network environments. The switch provides up to 48Gbps of switching capacity and supports wire-speed performance on all ports. It also supports advanced traffic management features such as Quality of Service (QoS) and access control lists (ACLs) to help ensure that critical network traffic is prioritized and secure.

In terms of reliability, the switch has a number of features that contribute to its ability to maintain uptime and availability. It supports Cisco's Redundant Power System (RPS) for providing power redundancy, which can help prevent network downtime in case of power supply failure. The switch also supports Cisco's StackWise technology, which allows multiple switches to be connected and managed as a single logical unit, providing redundancy and increased scalability. Additionally, the switch is designed with a robust, rack-mountable metal housing, which can help protect it against physical damage.

Compliant Standards

The model Cisco Catalyst 2955T 12-port switch is compliant with several industry standards that ensure compatibility and interoperability with other networking equipment. Some of the compliant standards are:

  • IEEE 802.3: This standard defines the physical layer and data link layer of Ethernet networks. The switch is compliant with IEEE 802.3u (Fast Ethernet) and IEEE 802.3z (Gigabit Ethernet) standards.
  • IEEE 802.1D: This standard defines the spanning tree protocol (STP) which allows the switch to prevent loops in the network when multiple paths to a destination exist.
  • IEEE 802.1Q: This standard defines virtual LANs (VLANs) which allow the switch to segment the network into multiple virtual networks, providing isolation and security.
  • IEEE 802.1p: This standard defines quality of service (QoS) which allows the switch to prioritize different types of traffic based on their importance.
  • IEEE 802.1x: This standard defines port-based network access control which allows the switch to authenticate users before granting them access to the network.
  • SNMP: Simple Network Management Protocol (SNMP) is a standard protocol used for network management. The switch supports SNMP v1, v2c and v3, allowing it to be managed and monitored by network management systems.
  • RSTP (Rapid Spanning Tree Protocol)
  • MSTP (Multiple Spanning Tree Protocol)

By being compliant with these standards, the WS-C2955T-12 Cisco Catalyst 2955T 12-port switch can be easily integrated into existing networks and can communicate with other equipment that conforms to these standards.
