PRODUCT OVERVIEW
The Cisco Catalyst 4948-10GE delivers wire-speed throughput with low latency for data-intensive applications using a 136-Gbps 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.
Primary hardware features include:
•
Wire-speed performance for 10/100/1000 connectivity and wire-speed 10 Gigabit Ethernet uplinks
–
136-Gbps switching fabric with 102-Mpps forwarding rate for Layer 2 through 4
•
Power-supply redundancy for nonstop operation
–
1+1 redundant hot-swappable internal AC or DC power supplies
