sntp source-interface
Use this command to specify
the physical or logical interface to use as the source interface (source IP address) for
SNTP (Simple Network Time Protocol) unicast server configuration. If configured, the
address of source Interface is used for all SNTP communications between the SNTP server
and the SNTP client. 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. If the configured interface is down, the SNTP client falls back to
its default behavior.
