The Cisco Catalyst 4948-10GE delivers wirespeed throughput with low latency for data-intensive applications using a 136Gbps switching fabric with a 102 million packets per second (mpps) forwarding rate in hardware for Layer 2-4 traffic. High-performance switching is delivered regardless of the number of route entries or Layer 3 and 4 services enabled. Hardware-based Cisco Express Forwarding routing architecture allows for increased scalability and performance. X2 10 Gigabit Ethernet optics provide 20 Gigabit Ethernet wire-speed uplinks for maximum throughput of traffic.

This switch comes with robust security features, including prevention of man-in-the-middle and IP-spoofing attacks, access control lists (ACL), Secure Shell (SSH) Protocol versions 1 and 2 and Simple Network Management Protocol Version 3 (SNMPv3) for secure remote access and network management. It also offers comprehensive management options, including a dedicated 10/100 console port and dedicated 10/100 management port as well as remote in-band management through SNMP.
