The Cisco Catalyst 4500 Series
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus is optimized for wiring closets for medium-sized enterprises, education customers, or small enterprise or branch offices. In scenarios that require enhanced routing (Interior Gateway Routing Protocol [IGRP], Enhanced IGRP [EIGRP], Open Shortest Path First [OSPF], Intermediate System-to-Intermediate System [IS-IS], and Border Gateway Protocol [BGP]), NetFlow services, or higher performance and scalability, customers should consider other Layer 3-capable supervisor engines.

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.
Stateful Switchover (SSO) offers continuous packet forwarding during supervisor engine switchover. Information is fully synchronized between supervisors to allow the standby supervisor to immediately take over in subsecond time if the primary fails. In Service Software Upgrade (ISSU) allows customers to upgrade or downgrade complete Cisco IOS
® Software images with minimal to no disruption to the network when using a redundant Cisco Catalyst 4500 Series system with dual supervisors. It enables rapid, nondisruptive software upgrade for new line cards, new power supplies, new features, or bug fixes. ISSU offers continuous packet forwarding during the supervisor engine switchover running different Cisco IOS Software versions.
SSO and ISSU dramatically improve the network reliability and availability in a Layer 2 or Layer 3 environment. SSO and ISSU are essential for business-critical applications such as voice over IP (VoIP) to help ensure that VoIP calls are not dropped.
When the primary supervisor fails, the secondary supervisor assumes control of the chassis. This algorithm prevents oscillations between primary and secondary supervisors. Alerts are generated to the network-monitoring software if either fails. A supervisor switchover can be forced by software, or by the user through the console or with the Simple Network Management Protocol (SNMP).
Predictable Performance and Scalability
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus delivers a 64-Gbps switching fabric with a 48-million-packets-per-second (mpps) forwarding rate in hardware for Layer 2-4 traffic. Switching performance is independent of the number of route entries or advanced Layer 3 and 4 services enabled. The Cisco Catalyst 4500 Series is optimized for multimedia applications with its advanced multicast support and wire-speed switching in hardware. Protocol Independent Multicast (PIM) and Source Specific Multicast (SSM) are supported, providing end users with additional scalability to support multimedia applications.
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus supports Internet Group Management Protocol (IGMP) snooping in hardware, enhancing the performance of multimedia applications 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 4500 Series Supervisor Engine II-Plus offers superior per-port QoS features to help ensure that network traffic is optimally classified, prioritized, and scheduled to efficiently handle multimedia, time-sensitive (voice), and mission-critical applications. This supervisor engine can classify, police, and mark incoming packets, allowing the administrator to differentiate between traffic flows and to enforce policies based on granular QoS fields. Sharing, shaping, and strict priority configurations determine scheduling of egress traffic. This supervisor engine also supports Dynamic Buffer Limiting (DBL), a congestion-avoidance feature.
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus features a single console port and a single IP address to manage all features of the system. 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. This supervisor engine delivers a comprehensive set of management tools to provide the visibility and control required in the network. The supervisor engine can be managed with CiscoWorks or Cisco Network Assistant. Cisco Catalyst switches can be configured and managed to deliver end-to-end device, VLAN, traffic, and policy management. The LAN management solution bundle offers tools such as CiscoWorks Resource Manager Essentials and CiscoView. These Web-based management tools offer numerous services, including automated inventory collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions.
