What’s new in FortiOS 7.2.1

The following list contains new managed FortiSwitch features added in FortiOS 7.2.1:

• The set fortilink-l3-mode command is now deprecated. Instead, you can create a static inter-switch link (ISL) trunk and then enable or disable automatic VLAN configuration on the manually created (static) ISL trunk:

  config switch trunk

  edit <trunk_name>

  set static-isl enable

  set static-isl-auto-vlan {enable | disable}

  next

  end

• You can now use the FortiOS CLI to specify how often the managed FortiSwitch unit will send IGMP version-2 queries when the IGMP-snooping querier is configured:

  config switch-controller igmp-snooping

  set query-interval <10-1200> seconds

  end

  By default, queries are sent every 125 seconds. The value for aging-time must be greater than the value for query-interval.

• You can now use the FortiOS CLI to specify whether your managed FortiSwitch configuration is automatically backed up each time a user logs out or before a system upgrade is started. By default, both options are disabled.

• The commands for flooding IGMP reports and flooding multicast traffic on a specified managed switch interface have changed from:

  config switch-controller managed-switch

  edit <FortiSwitch_serial_number>

  config ports

  edit <port_name>

  set igmps-flood-reports {disable | enable}

  set igmps-flood-traffic {disable | enable}

  next

  end

  to:

  config switch-controller managed-switch

  edit <FortiSwitch_serial_number>

  config ports

  edit <port_name>

  set igmp-snooping-flood-reports {disable | enable}

  set mcast-snooping-flood-traffic {disable | enable}

  next

  end

  For example:

  config switch-controller managed-switch

  edit S524DF4K15000024

  config ports

  edit port3

  set igmp-snooping-flood-reports enable

  set mcast-snooping-flood-traffic enable

  next

  end
