The Cisco Catalyst 4500 Series Supervisor Engine II-Plus integrates resiliency for advanced control of converged networks.
Overview
The Cisco Catalyst 4500 Series Supervisor Engine II-Plus meets the needs of value-conscious customers seeking a flexible and scalable LAN solution. Optimized for end-user connectivity for medium-sized enterprises, 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, 3, and 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, Catalyst 4507R, Catalyst 4503E, Catalyst 4506E, and Catalyst 4507E chassis, and with Cisco Catalyst 4500 Series classic 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.
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 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
We prefer to ship UPS or FedEx, we also can ship DHL or US Postal Service. We can usually have it to your location overnight if needed. Additional Fee(s) may apply for special shipping. All equipment will ship from our warehouse located at our office in Springfield, MO. We can also ship overseas if needed and we only charge exact shipping costs. For most customers outside the USA and Canada, wire transfer is the only form of payment we will accept. Overseas customers can either arrange to have the equipment picked up in the USA or we will ship to your location by FedEx. We can also ship to a freight forwarder here in the USA. The purchaser will be required to pay for taxes and duties through customs in your home country.
