The WS-C4948 Cisco Catalyst 4948 48 Ports Managed Switch is ahigh-performance, high-availability switch designed for use inenterprise and data center environments. It offers a range of advancedfeatures and capabilities, including:High-speed switching: With 48 Gigabit Ethernet ports, the product canhandle large amounts of data traffic with ease, ensuring fast andreliable performance for all connected devices.
Advanced security: The switch includes a range of security features,including access control lists (ACLs), port security, and securityprotocols such as IEEE 802.1X and RADIUS.
Redundancy and high availability: The switch supports both redundancyand high availability features, such as hot-swappable power suppliesand fans, and the ability to configure multiple uplinks for failover.
Easy management: The switch can be easily managed and configured usingthe Cisco IOS command-line interface (CLI) or the Cisco NetworkAssistant software.
Compliant Standards of Catalyst Switch
Compliant standards refer to the specific protocols and guidelines thata device or system must adhere to in order to be considered compliantwith industry standards and regulations.The WS-C4948 Cisco Catalyst 4948 48 Ports Managed Switch is compliantwith several standards, including:IEEE 802.3: This standard defines the physical and data link layers ofthe OSI (Open Systems Interconnection) model and sets thespecifications for Ethernet networks. The part is compliant with IEEE802.3 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet standards.
IEEE 802.3x: This standard defines the flow control mechanism used infull-duplex Ethernet networks, ensuring that data is transmittedwithout error and at a consistent rate.
IEEE 802.1p: This standard defines the prioritization of networktraffic, allowing for the prioritization of time-sensitive data such asvoice and video.
IEEE 802.1Q: This standard defines the tagging of VLANs (Virtual LANs),allowing for the segregation of network traffic into different virtualnetworks.
IEEE 802.1w: This standard defines the Rapid Spanning Tree Protocol(RSTP), which allows for the efficient and rapid reconfiguration ofnetwork topology in the event of a link failure.
The product also conforms to several other industry standards,including SNMP, Telnet, and SSH for network management and control, andsupports a variety of security features such as access control listsand port security.Robust Security and Dynamic Quality
The WS-C4948 Cisco Catalyst 4948 48 Ports Managed Switch is ahigh-performance, enterprise-grade switch that offers robust securityfeatures and dynamic quality of service (QoS) capabilities.Security features include advanced access control lists (ACLs), 802.1xauthentication, and SSH/SSL encryption for secure remote management.The switch also supports Cisco TrustSec, which provides identity-basedsecurity and policy enforcement for all users and devices on thenetwork.The switch's dynamic QoS capabilities allow for real-time monitoringand adjustment of network traffic, ensuring that critical applicationsand services receive the necessary bandwidth and resources. The switchalso supports Quality of Service (QoS) policies, which can beconfigured to prioritize traffic based on application, user, or device.In addition, this model has a high-performance switching architectureand supports up to 48 Gigabit Ethernet ports, making it ideal forhigh-bandwidth applications such as data centers and large enterprisenetworks.General Information
