About the Cisco C4948: an advanced networking solution
The Cisco Catalyst 4948 is a high-performance switch designed for wire-speed Layer 2 to Layer 4 network switching, leveraging the reliable Cisco 4500 series architecture. Equipped with 48 Gigabit Ethernet ports, it delivers non-blocking forwarding rates, ensuring efficient data transfer with minimal latency. This makes the Catalyst 4948 ideal for data-intensive applications, such as video calling and other high-bandwidth tasks, with a switching capacity of up to 96 Gbps and a forwarding rate of 72 million packets per second (Mpps).
Key features of the Cisco Catalyst 4948 include high-speed connectivity, ensuring efficient data transfer throughout the network, and flexibility and scalability with its modular design, which includes several expansion slots to accommodate additional modules or line cards. The switch supports advanced Layer 2 and Layer 3 switching, including VLANs, VTP, RSTP, MSTP, OSPF, and BGP, for efficient network design, traffic management, and routing. It also offers robust security features such as ACLs, port security, SSH, and IEEE 802.1X to protect the network.
In terms of redundancy and reliability, the Catalyst 4948 features hot-swappable components, redundant power supplies, and field-replaceable fans, minimising downtime. Quality of Service (QoS) capabilities ensure traffic classification and queueing mechanisms to prioritise high-priority traffic and reduce latency. Network management is enhanced through web-based GUIs, CLIs, and SNMP, providing comprehensive control and troubleshooting options.
