Reference Guide

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. If the configured interface is down, the DNS client falls back to its default
behavior.
