logging syslog source-interface
This command configures the syslog source-interface (source IP address) for syslog server
configuration. The selected source-interface IP address is used for filling the IP header of management
protocol packets. This allows security devices (firewalls) to identify the source packets coming from the
specific switch. If a source-interface is not specified, the primary IP address of the originating
(outbound) interface is used as the source address.
Format logging syslog source-interface {unit/slot/port|{loopback
loopback-id}|{vlan vlan-id}}
Mode Global Config
