The WS-C4948 Cisco Catalyst 4948 48 Ports Managed Switch is a
high-performance, high-availability switch designed for use in
enterprise and data center environments. It offers a range of advanced
features and capabilities, including:
High-speed switching: With 48 Gigabit Ethernet ports, the product can
handle large amounts of data traffic with ease, ensuring fast and
reliable performance for all connected devices.
Advanced security: The switch includes a range of security features,
including access control lists (ACLs), port security, and security
protocols such as IEEE 802.1X and RADIUS.
Redundancy and high availability: The switch supports both redundancy
and high availability features, such as hot-swappable power supplies
and fans, and the ability to configure multiple uplinks for failover.
Easy management: The switch can be easily managed and configured using
the Cisco IOS command-line interface (CLI) or the Cisco Network
Assistant software.
Compliant Standards of Catalyst Switch
Compliant standards refer to the specific protocols and guidelines that
a device or system must adhere to in order to be considered compliant
with industry standards and regulations.
The WS-C4948 Cisco Catalyst 4948 48 Ports Managed Switch is compliant
with several standards, including:
IEEE 802.3: This standard defines the physical and data link layers of
the OSI (Open Systems Interconnection) model and sets the
specifications for Ethernet networks. The part is compliant with IEEE
802.3 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet standards.
IEEE 802.3x: This standard defines the flow control mechanism used in
full-duplex Ethernet networks, ensuring that data is transmitted
without error and at a consistent rate.
IEEE 802.1p: This standard defines the prioritization of network
traffic, allowing for the prioritization of time-sensitive data such as
voice and video.
IEEE 802.1Q: This standard defines the tagging of VLANs (Virtual LANs),
allowing for the segregation of network traffic into different virtual
networks.
IEEE 802.1w: This standard defines the Rapid Spanning Tree Protocol
(RSTP), which allows for the efficient and rapid reconfiguration of
network 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, and
supports a variety of security features such as access control lists
and port security.
Robust Security and Dynamic Quality
The WS-C4948 Cisco Catalyst 4948 48 Ports Managed Switch is a
high-performance, enterprise-grade switch that offers robust security
features and dynamic quality of service (QoS) capabilities.
Security features include advanced access control lists (ACLs), 802.1x
authentication, and SSH/SSL encryption for secure remote management.
The switch also supports Cisco TrustSec, which provides identity-based
security and policy enforcement for all users and devices on the
network.
The switch's dynamic QoS capabilities allow for real-time monitoring
and adjustment of network traffic, ensuring that critical applications
and services receive the necessary bandwidth and resources. The switch
also supports Quality of Service (QoS) policies, which can be
configured to prioritize traffic based on application, user, or device.
In addition, this model has a high-performance switching architecture
and supports up to 48 Gigabit Ethernet ports, making it ideal for
high-bandwidth applications such as data centers and large enterprise
networks.
