More Features of this Item

The WS-X6748-SFP is a Cisco Catalyst 6000 48-port Gigabit Ethernet Fabric Module. It is designed to provide high-speed, Gigabit Ethernet connectivity for the Cisco Catalyst 6000 series switches. The module supports 48 Gigabit Ethernet ports, which can be configured as either SFP or SFP+ ports. The SFP ports support both standard and enhanced SFPs and the SFP+ ports support both standard and enhanced SFP+ modules. This allows for a flexible and scalable network infrastructure that can adapt to changing network requirements.

The module also supports advanced features such as Quality of Service (QoS), security, and network management. QoS allows for the prioritization of different types of traffic, ensuring that critical data is transmitted more quickly and efficiently. Security features such as Access Control Lists (ACLs) and Virtual LANs (VLANs) can be used to control access to the network and segment it into different virtual networks. Network management features such as Simple Network Management Protocol (SNMP) and CiscoWorks allow for the monitoring and management of the network from a central location.

Scalable and Reliable Networking

The WS-X6748-SFP Cisco Catalyst 48 Ports Managed Switch is designed for scalable and reliable networking. Some of the features that enable this include:

  • High port density: With 48 ports, the switch can support a large number of devices, making it suitable for growing networks.
  • High-performance switching: The switch supports wire-speed switching, which means that it can handle a large amount of network traffic without any performance degradation.
  • StackWise and StackWise Plus technology: This allows multiple switches to be stacked together for increased scalability and redundancy, which can be useful for growing networks.
  • Cisco StackPower technology: This allows power to be shared between multiple switches in a stack, which can increase the availability of the network.
  • Cisco IOS Software: This is a powerful operating system that provides a wide range of features and capabilities, including security, QoS, and IPv6 support.
  • Advanced Quality of Service (QoS): This feature allows you to prioritize network traffic, which can help ensure that critical applications receive the bandwidth they need.
  • Cisco EnergyWise: This feature allows you to monitor and control energy consumption, which can help reduce costs and improve the sustainability of your network.
  • Cisco Security features: This switch supports several security features such as Access Control Lists (ACLs), IEEE 802.1x port-based authentication, and Secure Shell (SSH) for secure remote management.

These features make the WS-X6748-SFP switch suitable for a variety of networking environments, from small to large enterprises.

Compliant Standards

The model Cisco Catalyst 6000 48-Port Gigabit Ethernet Fabric Module is compliant with several standards, including IEEE 802.3 and IEEE 802.3z.

IEEE 802.3 is a standard that specifies the physical layer and Media Access Control (MAC) layer of the Ethernet protocol. It defines the physical characteristics of the Ethernet cable and the format of the data that is transmitted over the cable. The WS-X6748-SFP module is compliant with IEEE 802.3, which means it can be used to connect devices that conform to the standard.

IEEE 802.3z is a standard that defines the Gigabit Ethernet protocol. It specifies the physical layer and MAC layer for Gigabit Ethernet, which is a faster version of Ethernet that supports data rates of 1 Gbps. This module is compliant with IEEE 802.3z, which means it can be used to connect devices that conform to the standard.

Additionally, the model is also compliant with other standards such as IEEE 802.1p, IEEE 802.1Q, and IEEE 802.3ad. IEEE 802.1p is a standard that defines the Quality of Service (QoS) for Ethernet networks, allowing for the prioritization of different types of traffic. IEEE 802.1Q is a standard that defines Virtual LANs (VLANs), which can be used to segment a network into different virtual networks. IEEE 802.3ad is a standard that defines Link Aggregation Control Protocol (LACP), which allows for the bundling of multiple physical links into a single logical link, providing increased bandwidth and improved reliability.
