Overview
FabricPath
FabricPath brings the benefits of Layer 3 routing to Layer 2 switched networks to build a highly resilient and
scalable Layer 2 fabric. The system manager is responsible for starting the FabricPath resources process and
monitoring heartbeats.
EEE
Energy Efficient Ethernet (EEE) is an IEEE 802.3az standard that is designed to reduce power consumption
in Ethernet networks during idle periods. EEE can be enabled on devices that support low power idle (LPI)
mode. Such devices can save power by entering LPI mode during periods of low utilization. In LPI mode,
systems on both ends of the link can save power by shutting down certain services. EEE provides the protocol
needed to transition into and out of LPI mode in a way that is transparent to upper layer protocols and
applications.
Troubleshooting Features
Cisco NX-OS provides troubleshooting tools such as ping, traceroute, Ethanalyzer, and the Blue Beacon
feature.
When a service fails, the system generates information that can be used to determine the cause of the failure.
The following sources of information are available:
• Every service restart generates a syslog message of level LOG_ERR.
• If the Smart Call Home service is enabled, every service restart generates a Smart Call Home event.
• If SNMP traps are enabled, the SNMP agent sends a trap when a service is restarted.
• When a service failure occurs on a local module, you can view a log of the event by entering the show
• When a service fails, a system core image file is generated. You can view recent core images by entering
• CISCO-SYSTEM-MIB contains a table for cores (cseSwCoresTable).
processes log command in that module. The process logs are persistent across supervisor switchovers
and resets.
the show cores command on the active supervisor. Core files are not persistent across supervisor
switchovers and resets, but you can configure the system to export core files to an external server using
the file transfer utility Trivial File Transfer Protocol (TFTP) by entering the system cores command.
