Timed Configuration Download, MAC-Based
VLANs
To allow centralized control of MAC-based VLANs over multiple
switches, a timed TFTP configuration download allows you to
download incremental configuration files from a primary or
secondary server at specified time intervals. The timed downloads
are configurable in 24-hour intervals. When a switch reboots, the
configuration is automatically downloaded according to primary
and secondary server settings.
To configure the primary and/or secondary server and file name, use
this command:
configure download server [primary | secondary]
<host_name> | <ip_address> <filename>
To enable timed interval downloads, use this command:
download configuration every <hour> <min>
To display timed download information, use this command:
show switch
