The Cisco Catalyst 4500 Supervisor Engine 6-E is compatible with classic Cisco Catalyst 4500 line cards, chassis, and power supplies, providing full investment protection. The Supervisor Engine 6-E delivers 24 Gbps per slot of switching capacity when deployed with the E-Series line cards in a Cisco Catalyst 4500 E-Series chassis. You can mix and match classic line cards and E-Series line cards within a Cisco Catalyst 4500 E-Series chassis with no performance degradation. When you deploy the Cisco Catalyst Supervisor Engine 6-E with classic line cards, all of the new features except the 24-Gbps per-slot switching capacity are inherited.
The Cisco Catalyst Supervisor Engine 6-E also provides flexibility and an easy migration path to 10 Gigabit Ethernet uplinks with dual-purpose X2 slots that can accommodate wire-speed 10 Gigabit Ethernet optics or Cisco Twin Gigabit Converter modules (Figure 2), enabling Gigabit Ethernet SFP optics.
The Cisco Twin Gigabit Converter Module, which ships standard with the Supervisor Engine 6-E (unless you order 10 Gigabit Ethernet optics on the configuration tool), converts a single 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet port slots that can be populated with appropriate SFP optics, providing a total of 4 Gigabit Ethernet uplinks if used in both X2 interface slots. With the flexibility offered by the Cisco Twin Gigabit Converter Module, you can initially use the gigabit uplinks and then, as your business demands change, you can simply remove the Cisco Twin Gigabit Converter Module and insert 10 Gigabit Ethernet X2 optics to provide full line-rate 10 Gigabit Ethernet uplinks without having to upgrade. The ability to support both Gigabit Ethernet uplinks and 10 Gigabit Ethernet uplinks on a single supervisor engine further demonstrates the flexibility and the investment protection of the Cisco Catalyst 4500 Series.

High Availability and Uplinks

The Cisco Catalyst 4500 Series was designed for nonstop communications with uninterrupted hardware switching. In addition to redundant power supplies, fans, and clock modules, the Cisco Catalyst 4510R-E, 4510R+E, 4507R+E, and 4507R-E chassis models support 1 + 1 supervisor engine redundancy, using the Supervisor Engine 6-E. The primary supervisor engine is active and is responsible for normal system operation. The other supervisor engine serves as a secondary standby, monitoring the operation of the primary supervisor engine.
Alerts are generated to the network monitoring software if either of the redundant supervisors fails. Hot-swapping of supervisor engines is supported without disrupting system operation. You can configure software to force switchover of supervisor engines, or you can use the Simple Network Management Protocol (SNMP) to perform switchover. The resiliency features of the Cisco Catalyst 4500 prevent network outages that could result in lost business and revenue.
Nonstop Forwarding with Stateful Switchover (NSF/SSO) offers continuous packet forwarding during supervisor engine switchover. Information is fully synchronized between supervisor engines to allow the standby supervisor engine 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 network disruption when using a redundant Cisco Catalyst 4500 E-Series system with dual supervisor engines. Facilitating rapid, undisruptive 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 releases.
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). These features help ensure that VoIP calls are not dropped.

Simplified and Scalable Network Virtualization with Easy Virtual Network (EVN)

Enterprise networks use single foundational infrastructure to build multiple logical overlay networks for diversified closed usergroups, regulatory, secure IT applications, etc. On campuses the traditional Multi-VRF solution is widely adopted and deployed to solve such network segmentation challenges. The Cisco Catalyst 4500E Series platform simplifies virtual network operation and maximizes scalability with the Cisco campus end-to-end Easy Virtual Network (EVN) technology.

Figure 3. Simplified Campus Network Virtualization with Cisco EVN

Cisco EVN is a successor solution that offers numerous advantages over traditional Multi-VRF technology:

• Simplified: To simplify campus virtual-network solutions, the Cisco EVN is designed with following three major components:

– Virtual network (VNET) trunk: The Cisco EVN solution reduces 98 to 99 percent of configuration complexities.

– Route replication: A simplified unicast and multicast route-leaking capability enables shared network and application services to virtual-network users. It replaces traditional Border Gateway Protocol (BGP)-based route-leaking mechanics.

– Routing context: Simplified and optimized virtual-network operation and troubleshooting are supported on a per-VRF basis.

• Scalable: Cisco EVN enables flexibility to scale up to 32 virtual network solutions - operationally 4x virtual-network scalability capacity over Multi-VRF technology.

• Interoperable: Cisco EVN provides network topology isolation based on an RFC-defined control plane; for example, Enhanced IGRP (EIGRP), Open Shortest Path First (OSPF), Multicast etc. The data-plane security and protection are maintained through industry-standard IEEE 802.1Q. In addition, the Cisco EVN-supported system interoperates with peer Cisco EVN, Multi-VRF, and MPLS systems.

Comprehensive Centralized Management

The Cisco Catalyst Supervisor Engine 6-E features a single console port and a single IP address to manage all system features. 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. USB drive support will be provided in a future software release. The Cisco Smartports macro for Cisco Catalyst switches is also supported, simplifying the configuration of the critical features for Ethernet networks.
The Cisco Catalyst 4500 Supervisor Engine 6-E is also FAT file system-capable, allowing images to be copied, saved, etc. with Windows-based machines with a Compact Flash. This capability will be available in a future software release.

Managed with CiscoWorks solutions, Cisco Catalyst switches can be configured and managed to deliver end-to-end device, VLAN, traffic, and policy management. The CiscoWorks LAN Management Solution (LMS) bundle offers tools such as CiscoWorks Resource Manager Essentials and CiscoView. These Web-based management tools offer several services, including automated inventory collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions.

Lower Total Cost of Ownership and Ease of Use with Smart Install Director

Smart Install Director simplifies management of images and configurations for enterprise switches in campus and branch networks. The Cisco Catalyst 4500E, now acting as Smart Install Director, provides a single management point for images and configuration of directly or indirectly connected Cisco Catalyst 2960, 3560, 3750, and 3850 Series Switches. It provides for:

• Plug and play in switch deployment

• Zero-touch replacement of switches with the same configuration and image as the switch it is replacing

• Single point of image and configuration management, in which configuration and image management are centralized

• On-demand image and configuration updates across all downstream switches from a single touchpoint

Smart Install Director reduces the customer's TCO and operational expense, while providing ease of use to the user.

Advanced Security

The Cisco Catalyst 4500 Supervisor Engine 6-E extends the rich set of industry-leading, integrated security features (Table 8) to proactively lock down a critical network infrastructure by supporting URPF in hardware. URPF helps prevents traffic spoofing by identifying traffic coming in on an unexpected port. The Cisco Catalyst 4500 Supervisor Engine 6-E also reduces network security risks with a rich set of Cisco 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 Supervisor Engine 6-E 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 Versions 1 and 2) Protocol, Secure Copy Protocol (SCP), and SNMPv3, respectively.
