The Cisco® Catalyst® 4500 Series integrates resiliency for advanced control of converged networks (Figure 1).

Figure 1.      Cisco Catalyst 4500 Series Supervisor Engine IV

Overview

The Cisco Catalyst 4500 Series Supervisor Engine IV integrates nonblocking Layers 2–4 switching with integrated resiliency, further enhancing control of converged networks. Converged data, voice, and video networks with high availability enable business resiliency for enterprise and Metro Ethernet customers deploying Internet-based business applications. Network control extends from the backbone to the edge with intelligent services such as granular quality of service (QoS), Internet security, and network management. Scalability of these intelligent network services is made possible with dedicated specialized resources known as ternary content addressable memory (TCAM). Ample TCAM resources (192,000 entries) enable “high feature capacity,” which provides wire-speed routing and switching performance with concurrent provisioning of services such as QoS and security, helping ensure scalability for today’s network requirements with ample room for future growth.

The modular architecture, media flexibility, and expandability of the Cisco Catalyst 4500 Series help enable an extended window of deployment in converged networks, reducing the total cost of ownership (TCO) by minimizing recurring operational expenses, in turn improving return on investment (ROI).

The Cisco Catalyst 4500 Series Supervisor Engine IV delivers next-generation switching technology with proven Cisco IOS® Software to power scalable, intelligent multilayer switching solutions for converged data, voice, and video networks. Optimized for the enterprise wiring closet, branch office, or Layer 3 distribution points, the Cisco Catalyst 4500 Series Supervisor Engine IV provides the performance and scalability to handle the network applications of today and the future.

* The amount of Software Based IPv6 entries supported is dependent on the DRAM spaceThe Cisco Catalyst 4500 Series is optimized for multimedia applications with its advanced multicast support. Protocol Independent Multicast (PIM), Source Specific Multicast (SSM), and Pragmatic General Multicast (PGM) are supported, giving you additional scalability to support multimedia applications. The supervisor engine IV also supports Internet Group Management Protocol (IGMP) Snooping in hardware, enhancing performance and reducing network traffic by allowing a switch to dynamically add and remove hosts from a multicast group.

Supervisor Engine IV Redundancy for Business Resiliency

The Cisco Catalyst 4507R chassis using the supervisor engine IV has been designed with an optional 1+1 redundant supervisor capability for integrated resiliency. One supervisor engine IV is designated as the primary (active) supervisor and is responsible for normal system operation; the other (secondary) can serve as a standby, monitoring the operation of the primary supervisor.

Nonstop Forwarding with Stateful Switchover (NSF/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 you to upgrade or downgrade complete Cisco IOS Software images with minimal to no disruption to the network when using a redundant Cisco Catalyst 4500 system with dual supervisors. It allows for a 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.

NSF/SSO and ISSU dramatically improve the network reliability and availability in a Layer 2 or Layer 3 environment. NSF/SSO and ISSU are essential for business-critical applications such as voice over IP (VoIP). With these features, VoIP calls are not dropped.

The supervisor engine IV redundancy scheme is similar to that of the supervisor engine V and V-10GE models. Alerts are generated to the network monitoring software if either supervisor fails, and hot-swapping of supervisors is supported without disrupting system operation. Either the software or you can force switchover of supervisor engines with Simple Network Management Protocol (SNMP). The resiliency features of the Cisco Catalyst 4500 Series help prevent network outages that could result in lost business and revenue. Table 3 gives high-availability and uplink options for the supervisor engines.

Advanced Security

The Cisco Catalyst 4500 Series offers a rich set of industry-leading, integrated security features to proactively lock down your critical network infrastructure. It reduces network security risks with a rich set of 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 4500 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 SNMPv3, respectively.

Cisco NAC is a foundational component of the Cisco Self-Defending Network strategy, improving the ability of the network to automatically identify, prevent, and respond to security threats. NAC helps enable 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.

Cisco NAC performs posture validation at the Layer 2 network edge for hosts with or without 802.1x enabled. You can isolate vulnerable and noncompliant hosts, give them reduced network access, or direct them to remediation servers based on organizational policy. By helping ensure that every host complies with security policy, you can significantly reduce the damage caused by infected hosts. NAC is available through standard software upgrades or Cisco SMARTnet® contracts on Cisco Catalyst switches.Table 6 gives security features of the supervisor engines.

Cisco Catalyst 4500 Series Netflow Services Card for Supervisor Engine IV

The Cisco Catalyst 4500 Series NetFlow Services Card (Figure 2) is an optional daughter card for the Cisco Catalyst 4500 Series Supervisor Engine IV or V, providing Layer 3 statistics and enhanced VLAN statistics without affecting the forwarding performance rates on the supervisor engine.

Figure 2.      Cisco Catalyst 4500 Series NetFlow Services Card and Supervisor Engine IV

NetFlow Services Card Product Description

NetFlow is a versatile feature that allows you to monitor traffic flows for the purpose of billing, network planning, or security purposes. The NetFlow services card supports per-packet statistics capture in hardware for flow- and VLAN-based statistics monitoring. NetFlow services capture and cache detailed information about each data flow (a stream of packets traveling in one direction from one endpoint to another across the network). Data in the NetFlow cache includes information about specific flows, including details such as IP addresses, packet and byte counts, time stamps, and application ports. You can export, collect, and analyze this data for numerous purposes such as virus and denial-of-service (DoS) mitigation. More information about NetFlow technology is available at: http://www.cisco.com/en/US/products/ps6601/products_ios_protocol_group_home.html.

NetFlow Services Card Applications

NetFlow technology efficiently provides the metering base for critical applications, including network traffic accounting, usage-based network billing, network planning, network monitoring, and data-mining capabilities for both service provider and enterprise customers.

An enterprise customer might use NetFlow information for departmental charge-backs, cost allocation, network budget justification, network monitoring and planning, application monitoring and planning, use monitoring and planning, enterprise accounting, usage-based billing, data warehousing, or management reports.

A service provider customer can use NetFlow information to charge customers according to bandwidth, application usage, QoS, or distance, rather than at a flat rate.

A more detailed list of general NetFlow applications is available at: http://www.cisco.com/en/US/products/ps6601/products_ios_protocol_group_home.html.

NetFlow Services Card Features

With Cisco IOS Software Release 12.1(13)EW, the Cisco Catalyst 4500 Series with the supervisor engine IV supports NetFlow statistics. The NetFlow daughter card provides line-rate flow statistics as well as Layer 2 VLAN statistics without a performance penalty. NetFlow Data Export (NDE) Versions 1 and 5 are supported in Cisco IOS Software Release 12.1(13)EW. Cisco IOS Software Release 12.1(19)EW provides several enhancements to the NetFlow daughter card, including support for NetFlow Version 8. NetFlow Version 8 enables aggregation of the NetFlow Data Export stream. Cisco IOS Software Release 12.1(19)EW also provides additional fields for NetFlow Version 5.

The default is NetFlow Statistics Collection and NetFlow Data Export Versions 1 and 5. The supported fields within NDE Version 5 with Cisco IOS Software Release 12.1(19)EW are identified as follows:

   Source and destination IP address (hardware)

   IP Protocol (hardware)

   Layer 4 source and destination ports (for TCP/User Datagram Protocol [UDP] or 0 otherwise) (hardware)

   Start and end time stamps (hardware)

   Packet counts and byte counts (hardware)

   Input/output interface (software)

   Next-hop router (software)

   Source and destination autonomous system number (software)

   Source and destination prefix mask (software)

   VLAN statistics collection

   Command-line interface (CLI) support for NetFlow and VLAN statistics

   SNMP support for VLAN statistics

   NetFlow Aggregation Support (NFX) (NetFlow Version 8)

NetFlow Services Card Hardware and Software Requirements

The NetFlow services card is supported only on the supervisor engine IV and V models with Cisco IOS Software and is not supported in the Cisco Catalyst OS Software.

Software Requirements

The minimum software versions are as follows:

   Supervisor engine IV with NetFlow services card: Cisco IOS Software Release 12.1(13)EW or later

   Supervisor engine V with NetFlow services card: Cisco IOS Software Release 12.2(18)EW or later

 

NetFlow Collection (NFC) and Network Data Analyzer (NDA) requirements:

   Cisco CNS NetFlow Collection Engine (NFC) Version 3.5 or later

   Cisco Network Data Analyzer (NDA) Version 3.6 or later

Hardware Requirements

   Supervisor engine IV or V is required.

   Redundant supervisor engine IV daughter card configurations must match. If a NetFlow services card is deployed on a primary supervisor engine, then a second NetFlow services card must be deployed on a secondary supervisor engine IV in the same chassis.

 

The NetFlow services card can be shipped preinstalled with a supervisor engine IV from the factory or as a separate, field-replaceable unit. The supervisor engine IV must be removed from the chassis to install the NetFlow services module; it is not hot-swappable.

New Cisco IOS Software Packaging for the Cisco Catalyst 4500 Series

Cisco announces a new Cisco IOS Software package for the Cisco Catalyst 4500 Series switches. This package creates a new foundation for features and functions, and provides consistency across all Cisco Catalyst switches. The new Cisco IOS Software release train is designated as 12.2SG.

Prior Cisco IOS Software images for the Cisco Catalyst 4500 Series, formally known as Basic L3 and Enhanced L3 images, now map to IP Base and Enterprise Services, respectively. BGP is now included in the Enterprise Services image. Unless otherwise specified, all currently shipping Cisco Catalyst 4500 software features based on Cisco IOS Software are supported in the Cisco IOS Software Release 12.2(25)SG, IP Base image with a few points to note:

   The IP Base image does not support the following routing-related features: BGP, EIGRP, OSPF, IS-IS, IPX, Apple Talk, VRF-lite, and PBR.

   The IP Base image supports EIGRP Stub for Layer 3 routing on all Cisco Catalyst 4500 Series Supervisor Engines. For more information about EIGRP Stub functions, visit: http://www.cisco.com/en/US/technologies/tk648/tk365/technologies_white_paper0900aecd8023df6f.shtml.

   The Enterprise Services image supports all Cisco Catalyst 4500 Series software features based on Cisco IOS Software, including enhanced routing. Customers planning to enable BGP on supervisor engine IV, V, or V-10GE models no longer need to purchase a separate BGP license (FR-IRC4); BGP capability is included in the Enterprises Services package.
