Details Information
The WS-C3550-24PWR-SMI is a Cisco Catalyst 3550 series managed switch. It has 24 Ethernet ports and is designed for use in enterprise-level networks.
The switch is managed, which means that it can be configured and monitored using a web interface or command-line interface (CLI). This allows network administrators to set up and control the switch's various features, including VLANs, Quality of Service (QoS), and security settings.
One of the key features of this switch is its Power over Ethernet (PoE) capability. This allows the switch to power devices such as IP phones and wireless access points through the Ethernet cable, eliminating the need for separate power supplies.
The switch also supports advanced features such as:
- Layer 2 switching: The switch can forward and filter data based on MAC addresses, allowing it to create VLANs and control traffic between them.
- Layer 3 routing: The switch can also perform IP routing, allowing it to forward data based on IP addresses and create multiple IP subnets.
- Quality of Service (QoS): The switch can prioritize certain types of network traffic, such as voice or video, to ensure that they are delivered with minimal delay and interruption.
- FlexStack: This feature allows multiple switches to be connected and managed as a single logical unit, increasing the scalability and flexibility of the network.
Resiliency and High Availability
The WS-C3550-24PWR-SMI is a Cisco Catalyst switch that offers 24 ports of Ethernet connectivity, and is designed for use in enterprise-level networks. The switch is a managed device, which means it can be configured and monitored through a web interface or command-line interface.
One of the key features of this product is its support for resiliency and high availability. This means that the switch has built-in features that help to ensure that the network remains up and running, even in the event of a failure or outage.
For example, the switch supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) which helps in loop prevention and redundancy, and also support for Hot Standby Router Protocol (HSRP) which allows for automatic failover to a secondary device in case the primary device fails.
Additionally, the switch also supports Power over Ethernet (PoE) which allows power to be delivered to devices such as wireless access points and IP phones over the Ethernet cables, eliminating the need for separate power cables and outlets.
Compliant Standards
The WS-C3550-24PWR-SMI is a Cisco Catalyst switch that has 24 ports of Ethernet and is managed, which means it can be configured and monitored using Cisco's network management software. This switch is compliant with a number of industry standards, including:
- IEEE 802.3: This standard defines the physical layer and data link layer specifications for Ethernet networks. The switch is compliant with IEEE 802.3 10BASE-T, IEEE 802.3u 100BASE-TX, and IEEE 802.3ab 1000BASE-T standards, which means it can support various speeds of Ethernet network.
- IEEE 802.3af: This standard defines Power over Ethernet (PoE) specifications, which allows the switch to provide power to devices connected to it over the Ethernet cable.
- IEEE 802.3at: This standard is also known as PoE+ and increases the maximum power output to 30 watts per port, providing more power for devices such as wireless access points and IP phones.
- IEEE 802.3x: This standard defines flow control and full-duplex operation for Ethernet networks, which helps to prevent network congestion and improve network performance.
- IEEE 802.1D: This standard defines the Spanning Tree Protocol (STP), which is a network protocol that helps prevent loops in a network by shutting down redundant links.
- IEEE 802.1Q: This standard defines Virtual LANs (VLANs), which allow for the creation of multiple logical networks within a single physical network.
- IEEE 802.1p: This standard defines Quality of Service (QoS) priorities, which can be used to prioritize different types of network traffic.
- IEEE 802.1w: This standard defines Rapid Spanning Tree Protocol (RSTP), which is an evolution of STP that improves network convergence times.
- IEEE 802.1s: This standard defines Multiple Spanning Tree Protocol (MSTP), which allows for the creation of multiple STP instances within a single network.
