The switch logs the most recent 100 messages of severity 0, 1, or 2 to the NVRAM log. You cannot configure
logging to the NVRAM.
You can configure which system messages should be logged based on the facility that generated the message
and its severity level.

syslog Servers
syslog servers run on remote systems that are configured to log system messages based on the syslog protocol.
You can configure the Cisco Nexus 5000 Series to sends its logs to up to three syslog servers.
To support the same configuration of syslog servers on all switches in a fabric, you can use the Cisco Fabric
Services (CFS) to distribute the syslog server configuration.
When the switch first initializes, messages are sent to syslog servers only after the network is initialized.Note
