PRODUCT MIGRATION OPTIONS
The recommended replacements for the affected Cisco Catalyst 2950 Series are the Cisco Catalyst 3560 Series Switches and the Cisco Catalyst 2960
Series Switches. However, higher port-density deployments may be better suited to Cisco StackWise™ technology available only in the Cisco
Catalyst 3750 Series. Table 3 lists the part numbers affected by this end-of-sale announcement and identifies the recommended replacement
product(s). Table 4 provides a comparison between these product lines.
The Cisco Catalyst 2960 Series is a new family of fixed-configuration standalone devices that provide desktop Fast Ethernet and Gigabit Ethernet
connectivity for entry-level enterprise, midmarket, and branch-office networks. All Cisco Catalyst 2960 Series switches support the same software
image, which offers integrated security, including Network Admission Control (NAC), advanced QoS, high resiliency, and intelligent services for
the network edge.
The Cisco Catalyst 3750 and 3560 Series take this further with increased scalability, functionality, and security options. Both series support IEEE
802.3af Power over Ethernet (PoE) and Cisco prestandard PoE functionality, advanced routing capability, enhanced security, and IPv6 in Fast
Ethernet and Gigabit Ethernet configurations. By combining both high-density Gigabit Ethernet and PoE, customers gain maximum productivity
and investment protection by enabling the deployment of new applications such as IP telephony, wireless access, video surveillance, building
management systems, and remote video kiosks. Additionally, the Cisco Catalyst 3750 and 3560 series support features such as Dynamic ARP
Inspection, IP Source Guard, and DHCP Snooping in the Cisco IOS
®
Software IP Base image. These software features mitigate many of the
increasingly common internal security threats seen in LANs and defend against a variety of man-in-the-middle and spoofing attacks.
Unique to the Cisco Catalyst 3750 Series is Cisco StackWise, a revolutionary stacking architecture that brings high levels of resiliency, automation,
and performance to stackable switches. With Cisco StackWise technology, customers can create a single, 32-Gbps switching unit with up to nine
Cisco Catalyst 3750 Series switches. A working stack is self-managing and self-configuring. When switches are added or removed, the master
switch automatically loads the Cisco IOS Software release running on the stack to the new switch, loads the global configuration parameters, and
updates all routing tables to reflect the changes.
