Scalable and High-Performance
Scalability refers to the ability of a device or system to handle an increasing amount of workload or traffic without a significant decrease in performance. The WS-C4948-E Cisco Catalyst 4948 is scalable because it can support a large number of devices and users, and it can handle a high amount of traffic without becoming overwhelmed. This is achieved through the use of advanced hardware and software technologies, such as specialized processors and memory, and high-speed switching fabrics.
High-performance refers to the ability of a device or system to process and transmit data quickly and efficiently. The WS-C4948-E Cisco Catalyst 4948 is high-performance because it can handle a large amount of traffic at high speeds, and it can process data quickly using specialized hardware and software technologies. This allows the switch to handle demanding applications and services such as video conferencing, data backup and recovery, and virtualization. Additionally, The switch also support advanced features such as Quality of Service (QoS), Access Control Lists (ACLs), and Link Aggregation Control Protocol (LACP) which allows to prioritize, filter and bundle multiple physical links to provide high-performance and redundancy.
Secure and Efficient Network Management
The WS-C4948-E Cisco Catalyst 4948 supports secure and efficient network management through a variety of features and protocols.
One way it provides security is by supporting advanced security features such as access control lists (ACLs), which can be used to restrict access to the network based on specific criteria such as IP address or port number. Additionally, the switch also support features such as 802.1X authentication and Role-Based Access Control (RBAC) which allows to restrict access based on user roles.
Another way it provides security is by supporting various security protocols such as SSH, SSL, and SNMPv3 which encrypts the communication between the switch and the management station.
In terms of efficient network management, the WS-C4948-E Cisco Catalyst 4948 supports various management protocols such as Simple Network Management Protocol (SNMP), which allows for the monitoring and management of the switch through a network management system. The switch also supports Cisco's proprietary protocol, Cisco Discovery Protocol (CDP), which allows for the discovery and management of other Cisco devices on the network. Additionally, the switch also supports web-based management through a web interface, which allows for easy and intuitive management of the switch.

Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
