Switched Port Analyzer
• Distributed device alias service
• SAN port channels
QoS
Cisco Nexus 5000 Series switches provide quality of service (QoS) capabilities such as traffic prioritization
and bandwidth allocation on egress interfaces.
The default QoS configuration on the switch provides lossless service for Fibre Channel and FCoE traffic.
QoS can be configured to provide additional classes of service for Ethernet traffic.
Virtual Port Channels
A virtual port channel (vPC) allows links that are physically connected to two different Cisco Nexus 5000
Series switches or Cisco Nexus 2000 Series Fabric Extenders to appear as a single port channel. A vPC can
provide multipathing, which allows you to create redundancy by enabling multiple parallel paths between
nodes and load balancing traffic where alternative paths exist.
Serviceability
The Cisco Nexus 5000 Series switch serviceability functions provide data for network planning and help to
improve problem resolution time.
Switched Port Analyzer
The switched port analyzer (SPAN) feature allows an administrator to analyze all traffic between ports by
nonintrusively directing the SPAN session traffic to a SPAN destination port that has an external analyzer
attached to it.
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.
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. The feature offers alert
grouping capabilities and customizable destination profiles. This feature can be used, 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). This
feature is a step toward autonomous system operation, which enables networking devices to inform IT when
a problem occurs and helps to ensure that the problem is resolved quickly.
