Data Sheet
Cisco Catalyst 4948 Series Switch
High-Performance, Rack-Optimized Server Switching
PRODUCT OVERVIEW
The Cisco® Catalyst® 4948 is a wire-speed, low-latency, Layer 2–4, 1 rack unit (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 Series offers
exceptional performance and reliability for low density, multilayer aggregation of high performance servers and workstations. High
performance and scalability of intelligent network services is made possible with dedicated specialized resources known as ternary content
addressable memory (TCAM). Ample TCAM resources (64,000 entries) enable “high feature capacity,” which provides wire-speed
routing/switching performance with concurrent provisioning of services such as QoS and security. This helps ensure scalability for today’s
network requirements with ample room for future growth.
The Cisco Catalyst 4948 offers 48 ports of wire-speed 10/100/1000BASE-T with 4 alternative wired ports that can accommodate optional
1000BASE-X Small Form-Factor Pluggable (SFP) optics1. 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 (refer to Figures 1 and 2).

The Cisco Catalyst 4948 has 52 physical switching ports (48 10/100/1000 and 4 SFP) on the front panel. Up to 48 of these ports can be active at one time
in any combination.

KEY FEATURES AND BENEFITS
Wire-Speed Performance for 10/1 00/1 000 Connectivity
The Cisco Catalyst 4948 delivers wire-speed throughput with low latency for data-intensive applications using a 96 Gbps switching fabric
with a 72 Mpps forwarding rate in hardware for Layer 2–4 traffic. Switching performance is guaranteed 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.
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 maximum deployment flexibility. The Cisco Catalyst 4948 also has a hot-swappable fan
tray with four redundant fans for additional serviceability and availability.
Robust Security
Multiple server communities can be securely established on a single Cisco Catalyst 4948. 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 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 for auditing.
The Cisco Catalyst 4900 Series offers a rich set of integrated security features to proactively lock down your critical network infrastructure.
It reduces network security risks with a rich set of Network Admission Control (NAC) capabilities and 802.1x-based user authentication,
authorization, and accounting (AAA). The security policy enforcement is uncompromised with the wire-rate, dedicated access-control lists
(ACLs) to fend off ever-increasing virus and security attacks. The Cisco Catalyst 4900 Series offers powerful, easy-to-use tools to
effectively prevent untraceable man-in-the-middle attacks, control plane resource exhaustion, IP spoofing, and flooding attacks, without
any change to the end-user or host configurations. Secure remote access, file transfers, and network management are accomplished with the
Secure Shell (SSH Version 1 and Version 2) Protocol, Secure Copy Protocol (SCP), and Simple Network Management Protocol (SNMP)
v3, respectively.
Network Admission Control (NAC) is a foundational component of the Cisco Self-Defending Network strategy, improving the network’s
ability to automatically identify, prevent, and respond to security threats. NAC enables the Cisco Catalyst switches to collaborate with
third-party solutions for security-policy compliance and enforcement before a host is permitted to access the network.
NAC performs posture validation at the Layer 2 network edge for hosts with or without 802.1x enabled. Vulnerable and noncompliant
hosts can be isolated, given reduced network access or directed to remediation servers based on organizational policy. By ensuring that
every host complies with security policy, organizations can significantly reduce the damage caused by infected hosts. NAC is available
through standard software upgrades or Cisco SMARTnet contracts on Cisco Catalyst switches.
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 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 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 Cisco Works solutions and embedded Cisco View, 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.

New Cisco IOS Software Packaging for the Cisco Catalyst 4900 Series
Cisco Systems® announces a new Cisco IOS Software package for the Cisco Catalyst 4900 Series, creating a new foundation for features
and functionality, and offering consistency across all Catalyst switches. The new Cisco IOS Software release train is designated as 12.2SG.
Prior Cisco IOS Software images for the Catalyst 4900 Series, formally known as “Basic L3” (SMI) and “Enhanced L3” (EMI) images,
now map to “IP Base” and “Enterprise Services,” respectively. Unless otherwise specified, all currently shipping Catalyst 4900 software
features based on Cisco IOS Software are supported in the 12.2(25)SG, IP Base image with a few points to note:
The IP Base image will not support the following routing related features: BGP, EIGRP, OSPF, IS-IS, IPX, Apple Talk, Virtual
Route Forwarding [VRF]-lite, and Policy-Based Routing [PBR])
The IP Base image will support EIGRP-Stub for Layer 3 routing on all Catalyst 4900 Series Supervisor Engines. For more
information on EIGRP¬Stub functionality, go to
http://www.cisco.com/en/US/tech/tk365/technologies_white_paper0900aecd8023df6f.shtml
The Enterprise Services image supports all Catalyst 4900 Series software features based on Cisco IOS Software, including enhanced
routing. Table 1 shows a more detailed description of the feature differences between the IP Base and Enterprise Services (ES) images.
