Wire-Speed Performance for 10/100/1000 Connectivity :
The Cisco Catalyst 4948 delivers wire-speed throughput with low latency for data-intensive applications, using a 96-
Gbps switching fabric with a forwarding rate of 72 million packets per second (mpps) in hardware for Layer 2 to 4
traffic. Switching performance remains high regardless of the number of route entries or Layer 3 and 4 services
enabled. Hardware-based Cisco Express Forwarding routing architecture enables increased scalability and
performance.

Power Supply Redundancy for Nonstop Operation:
The Cisco Catalyst 4948 provides reliability for critical applications, with 1+1 redundant hot-swappable internal AC or
DC power supplies. The 1+1 power supply design provides A-to-B failover when power supplies are connected to
different circuits. AC and DC power supplies can be mixed in the same unit for outstanding deployment flexibility. The
Cisco Catalyst 4948 also has a hot-swappable fan tray with four redundant fans for additional serviceability and
availability.

Comprehensive Management:
The Cisco Catalyst 4948 includes a single, dedicated 10/100 console port and a single, dedicated 10/100
management port for offline disaster recovery. Remote in-band management is available with the Simple Network
Management Protocol (SNMP), Telnet client, Bootstrap Protocol (BOOTP), and Trivial File Transfer Protocol (TFTP).
Support for local or remote out-of-band management is delivered through a terminal or modem attached to the
console interface. The management port helps enable the Cisco Catalyst 4948 to reload a new image from a TFTP
server within seconds.
The Cisco Catalyst 4948 delivers a comprehensive set of management tools to provide the visibility and control
required for server switching. Managed with CiscoWorks solutions and embedded CiscoWorks CiscoView, the Cisco
Catalyst 4948 can be configured and managed to deliver device, VLAN, traffic, and policy management. These webbased
management tools offer numerous services, including software deployment and quick isolation of error
conditions.
