OVERVIEW
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus is a Cisco IOS® Software-based supervisor engine that meets the needs of value-conscious
customers seeking a flexible and scalable LAN solution. Optimized for end-user connectivity for medium-sized enterprises, education customers, or
small enterprises or branch offices, this supervisor engine provides the resiliency and control for converged data, voice, and video networks.
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus delivers nonblocking Layer 2–4 intelligent services to power-resilient, multilayer-
switching solutions for converged data, voice, and video networks. It allows customers to deploy networkwide intelligent services, such as advanced
quality of service (QoS), comprehensive security, and management with optimal control and resiliency. Compatible with the Cisco Catalyst 4503,
Catalyst 4506, and Catalyst 4507R chassis, and with existing Cisco Catalyst 4500 Series line cards, the Cisco Catalyst 4500 Series Supervisor Engine
II-Plus helps to ensure an extended window of deployment of the modular Cisco Catalyst 4500 Series (Table 1).

CISCO CATALYST 4500 SERIES SUPERVISOR ENGINE II-PLUS REDUNDANCY FOR BUSINESS RESILIENCY
The Cisco Catalyst 4507R chassis has been designed with optional 1 + 1 redundant supervisor capability using the Cisco Catalyst 4500 Series
Supervisor Engine II-Plus for integrated resiliency. One of these supervisor engines is designated as the primary (active) and is responsible for
normal system operation; the other (secondary) serves as a standby, monitoring the operation of the primary supervisor.
With the support of stateful switchover (SSO), information is synchronized between supervisors to allow the standby supervisor to immediately take
over in subsecond time if the primary fails. Layer 2 links are maintained transparently without the need of renegotiating sessions. As a result,
business-critical applications such as voice-over-IP (VoIP) calls are not dropped.
The redundancy scheme using the Cisco Catalyst 4500 Series Supervisor Engine II-Plus in the Cisco Catalyst 4507R is identical to that used by the
supervisor engines IV and V. When the primary supervisor fails, the secondary supervisor assumes control of the chassis. This algorithm prevents
