Features and Benefits
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 web-based management tools offer
numerous services, including software deployment and quick isolation of error conditions.
