Interface for System Log Messages To Use
source-interface interface-name
Configure outgoing system log messages to use a specific interface. The interface name can be a physical interface or a subinterface (a VLAN-tagged interface). The interface must be located in the same VPN as the syslog server. Otherwise, the configuration is ignored. If you configure multiple syslog servers, the source interface must be the same for all of them.
Message Priority
priority priority
Severity of the syslog message to save. The severity indicates the seriousness of the event that generated the message. priority can be one of the following:
emergency—System is unusable (corresponds to syslog severity 0).
alert—Action must be taken immediately (corresponds to syslog severity 1).
critical—A critical condition (corresponds to syslog severity 2).
error—An error condition that does not fully impair system usability (corresponds to syslog severity 3).
warn—A warning condition (corresponds to syslog severity 4).
notice—A normal, but significant condition (corresponds to syslog severity 5).
information—Routine condition (the default) (corresponds to syslog severity 6).
Server Name
name (dns-name | host-name | ip-address)
DNS name, hostname, or IP address of the system on which to store syslog messages. You can configure multiple syslog servers.
