CISCO CATALYST 4948-10GE SWITCH

10 Gigabit Ethernet Switching for High-Performance, Rack-Optimized Server Switching

PRODUCT OVERVIEW

The Cisco® Catalyst® 4948-10GE Switch is a wire-speed, low-latency, Layer 2–4, 1-rack-unit (1-RU), fixed-configuration switch for rack-optimized
server switching. Based on the proven Cisco Catalyst 4500 Series hardware and software architecture, the Cisco Catalyst 4948-10GE offers
exceptional performance, bandwidth, and reliability for low-density, multilayer aggregation of high-performance servers and workstations.

The Cisco Catalyst 4948-10GE offers 48 ports of wire-speed 10/100/1000BASE-T with 2 ports of wire-speed 10 Gigabit Ethernet (X2 optics).
Exceptional reliability and serviceability are delivered with optional internal AC or DC 1+1 hot-swappable power supplies and a hot-swappable
fan tray with redundant fans (Figures 1 and 2).

KEY FEATURES AND BENEFITS
Wire-Speed Performance in All Directions

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 maintained
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.

Power-Supply Redundancy for Nonstop Operation

The Cisco Catalyst 4948-10GE 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 maximum deployment flexibility. The Cisco Catalyst 4948-10GE also has a hot-swappable fan tray with four redundant
fans for additional serviceability and availability.

Robust Network Security

Multiple server communities can be securely established on a single Cisco Catalyst 4948-10GE. The switch can isolate different Layer 2 community
traffic simultaneously, while conserving IP address space. In an unlikely event that a server is compromised, the Cisco Catalyst 4948-10GE can
prevent man-in-the-middle and IP-spoofing attacks to the rest of community with no change to the server configuration. Such attacks can be logged
by the Cisco Catalyst 4948-10GE for auditing.

The Cisco Catalyst 4948-10GE offers a rich blend of network-traffic security capabilities. Security policies can be easily defined with access control
lists (ACLs). All ACL lookups are done in hardware, so wire-speed forwarding and routing performance are not affected when enabling ACL-based
wire-rate security in the network. The Cisco Catalyst 4948-10GE also supports Secure Shell (SSH) Protocol Version 1 and 2 and Simple Network
Management Protocol Version 3 (SNMPv3) for secure remote access and network management.

Comprehensive Management

The Cisco Catalyst 4948-10GE 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 SNMP, Telnet client, 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 4948-10GE to reload a new image from a TFTP server within seconds.

The Cisco Catalyst 4948-10GE 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 4948-10GE 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.

PREDICTABLE PERFORMANCE AND SCALABILITY

The Cisco Catalyst 4948-10GE is optimized for multimedia applications with its advanced multicast support. It supports Protocol Independent
Multicast (PIM), Source Specific Multicast (SSM), and Pragmatic General Multicast (PGM), providing end users with additional scalability to
support multimedia applications. Also supported is Internet Engineering Task Force (IGMP) snooping in hardware, enhancing performance and
reducing network traffic by allowing a switch to dynamically add and remove hosts from a multicast group.

INTELLIGENT NETWORK SERVICES WITH QOS AND SOPHISTICATED TRAFFIC MANAGEMENT

The Cisco Catalyst 4948-10GE offers superior per-port quality of service (QoS) features to help ensure that network traffic is classified, prioritized,
and scheduled optimally to efficiently manage bandwidth-hungry multimedia, and time-sensitive and mission-critical applications. The Catalyst
4948-10GE can classify, police, and mark incoming packets, allowing the administrator to differentiate between traffic flows and enforce policies.
