Product Overview
This chapter provides an overview of the Cisco NX-OS software and includes the following sections:
•
Cisco NX-OS Software for the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter
•
Cisco NX-OS Software for the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter
This section describes the Cisco NX-OS software for the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter.
The Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter (also referred in this document as the switch) is a Layer 2 device, which runs Cisco NX-OS. The Cisco NX-OS Release 4.1.2 based software supports the Cisco Nexus 4001I and 4005I Switch Module for IBM BladeCenter including certain features that are specific to the product. The Cisco NX-OS software also interoperates with any networking operating system that conforms to the IEEE and RFC compliance standards.
The switch is a 10/1-Gb Ethernet switch for the IBM BladeCenter chassis. The switch offers a solution in high-end data centers where server virtualization and I/O consolidation are required.
This section includes the following topics:
•
Common Software Throughout the Data Center
The Cisco NX-OS software provides a unified operating system that is designed to run all areas of the data center network including the LAN and Layer 4 through Layer 7 network services.
Modular Software Design
The Cisco NX-OS software supports distributed multithreaded processing on symmetric multiprocessors (SMPs), multi-core CPUs, and distributed data module processors. The Cisco NX-OS software offloads computationally intensive tasks, such as hardware table programming, to dedicated processors distributed across the data modules. The modular processes are created on demand, each in a separate protected memory space. Processes are started and system resources are allocated only when you enable a feature. A real-time preemptive scheduler helps to ensure the timely processing of critical functions.
Serviceability
The Cisco NX-OS software has serviceability functions that allow the device to respond to network trends and events. These features help you with network planning and improving response times.
This section includes the following topics:
Switched Port Analyzer
The Switched Port Analyzer (SPAN) feature allows you to analyze all traffic between ports (called the SPAN source ports) by nonintrusively directing the SPAN session traffic to a SPAN destination port that has an external analyzer attached to it. For more information about SPAN, see Chapter 34 "Configuring SPAN."
Ethanalyzer
Ethanalyzer is a Cisco NX-OS protocol analyzer tool based on the Wireshark (formerly Ethereal) open source code. Ethanalyzer is a command-line version of Wireshark for capturing and decoding packets. You can use Ethanalyzer to troubleshoot your network and analyze the control-plane traffic. For more information about Ethanalyzer, see Chapter 35 "Troubleshooting."
Call Home
The Call Home feature continuously monitors hardware and software components to provide e-mail-based notification of critical system events. A versatile range of message formats is available for optimal compatibility with pager services, standard e-mail, and XML-based automated parsing applications. It offers alert grouping capabilities and customizable destination profiles.You can use this feature, for example, to directly page a network support engineer, send an e-mail message to a network operations center (NOC), and employ Cisco AutoNotify services to directly generate a case with the Cisco Technical Assistance Center (TAC). For more information about Call Home, see Chapter 25 "Configuring Call Home."
Online Diagnostics
The Online Health Management System (OHMS) is a hardware fault detection and recovery feature. It ensures the general health of the switch. For more information about OHMS, see Chapter 24 "Configuring Online Diagnostics."
Manageability
This section includes the following topics:
•
•
Simple Network Management Protocol
The Cisco NX-OS software is compliant with Simple Network Management Protocol (SNMP) version 1, version 2, and version 3. A large number of MIBs is supported. For more information about SNMP, see the chapters related to System Management.
Role-Based Access Control
With role-based access control (RBAC), you can limit access to device operations by assigning roles to users. You can customize access and restrict it to the users who require it. For more information about RBAC, see the chapters related to Switch Security Features.
Cisco NX-OS Device Configuration Methods
You can configure devices using the CLI from a Secure Shell (SSH) session or a Telnet session. SSH provides a secure connection to the switch. For more information on SSH and Talent, see the the chapters related to Switch Security Features.
You can also configure devices using the XML management interface, which is a programmatic method based on the NETCONF protocol that complements the CLI.
Traffic Routing, Forwarding, and Management
This section includes the following topics:
Ethernet Switching
The Cisco NX-OS software supports high-density, high-performance Ethernet systems and provides the following Ethernet switching features:
•
•
•
•
•
•
IP Multicast
The Cisco NX-OS includes the following multicast protocols and functions:
•
•
•
FCoE Initialization Protocol
The Cisco NX-OS supports the FIP snooping bridge feature. The switch operates as a loss-less Ethernet bridge transparently forwarding FCoE packets.
Quality of Service
The Cisco NX-OS Quality of Service (QoS) support allows you to classify the network traffic, police and prioritize the traffic flow, and provide congestion avoidance. For more information, see Chapter 30 "Configuring Quality of Service."
Network Security Features
Cisco NX-OS includes the following security features:
•
•
•
•
•
•
For more information, see the chapters related to Switch Security Features.
Typical Deployment Topology
The switch is typically deployed in a topology that is shown in Figure 1-1:
