Syslog Servers - Cisco Nexus 7000 Series Configuration Manual

Syslog Servers

System message logging is based on
the messages that the device generates, see the Cisco NX-OS System Messages Reference.
By default, the device outputs messages to terminal sessions and logs system messages to a log file.
The following table describes the severity levels used in system messages. When you configure the severity
level, the system outputs messages at that level and lower.
Table 10: System Message Severity Levels
Level
0 – emergency
1 – alert
2 – critical
3 – error
4 – warning
5 – notification
6 – informational
7 – debugging
The device 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
The syslog servers run on remote systems that log system messages based on the syslog protocol. You can
configure up to eight IPv4 or IPv6 syslog servers.
To support the same configuration of syslog servers on all switches in a fabric, you can use Cisco Fabric
Services (CFS) to distribute the syslog server configuration.
When the device first initializes, messages are sent to syslog servers only after the network is initialized.
