In a constantly changing business environment, companies are calling upon their IT departments to help them reduce costs, improve productivity, and introduce new ways to interact with their customer base. It uses data center-class Cisco ® NX-OS Software for high reliability and ease of management. The switch series is highly serviceable, with redundant, hot-pluggable power supplies and fan modules. The Cisco Nexus 5000 Series is designed for data center environments with cut-through technology that enables consistent low-latency Ethernet solutions, with front-to-back or back-to-front cooling, and with data ports in the rear, bringing switching into close proximity with servers and making cable runs short and simple. The Cisco Nexus 5000 Series portfolio also provides the flexibility to connect directly to servers using 10GBASE-T connections or fiber with Enhanced Small Form-Factor Pluggable (SFP+) transceivers. The switch series is compatible with integrated transceivers and Twinax cabling solutions that deliver cost-effective connectivity for 10 Gigabit Ethernet to servers at the rack level, eliminating the need for expensive optical transceivers. In addition to supporting standard 10 Gigabit Ethernet network interface cards (NICs) on servers, the Cisco Nexus 5000 Series integrates with multifunction adapters called converged network adapters (CNAs) that combine the functions of Ethernet NICs and Fibre Channel host bus adapters (HBAs), making the transition to a single, unified network fabric transparent and consistent with existing practices, management software, and OS drivers. Its ability to connect Fibre Channel over Ethernet (FCoE) to native Fibre Channel protects existing storage system investments while dramatically simplifying in-rack cabling. These features allow the switches to support multiple traffic classes over a lossless Ethernet fabric, thus enabling consolidation of LAN, SAN, and cluster environments. It supports a set of network technologies known collectively as Data Center Bridging (DCB) that increases the reliability, efficiency, and scalability of Ethernet networks. The switch series, using cut-through architecture, supports line-rate 10 Gigabit Ethernet on all ports while maintaining consistently low latency independent of packet size and services enabled. With low latency and choice of front-to-back or back-to-front cooling, copper or fiber access ports, and rear-facing data ports, the Cisco Nexus 5000 Series is designed for a broad range of physical, virtual, storage access, and high-performance computing environments, thus giving customers the flexibility to meet and scale their data center requirements in a gradual manner and at a pace that aligns with their business objectives. The rapid increase in in-rack computing density and the increasing use of virtualization software combine to accelerate the demand for 10 Gigabit Ethernet and consolidated I/O: applications for which the Cisco Nexus ® 5000 Series Switches are an excellent match. Today’s data centers are increasingly filled with dense rack-mount and blade servers that host powerful multicore processors. There are a number of approaches to creating Nessus scanning policies.Latest Additions to the Cisco Nexus 5000 Series SwitchesĬisco Nexus 5000 Series Switches Product Overview To perform this scan an IOS user with privilege 1 is sufficient. You may be running "IP Base" set which doesn't support MPLS but Nessus will show MPLS vulnerability. For example if there is a vulnerability in http server but your device doesn't have it enabled you are not vulnerable. Furthermore there are different feature sets of the same IOS version. You may be running version of IOS that has known vulnerabilities but your device may not be vulnerable. Third: our policy will include checks for IOS, CatOS and Linksys devices.įourth: Probably the most important one. Second: Nessus supports only SSH authentication for Cisco devices. You can export to the list of IPs from CiscoWorks or use NMAP scan and import result to Nessus. The reason for that is that someone could set up a rogue SSH server and intercept the credential you use for scanning. There are a few caveats to scanning Cisco switches with Nessus.įirst: I recommend scanning only specific management IP addresses of devices rather than network ranges.
