What’s new in FortiOS 7.4.1
The following list contains new managed FortiSwitch features added in FortiOS 7.4.1:
-
You can now make your Security Fabric more secure with the FortiLink secured fabric. The FortiLink secured fabric provides authentication and encryption to all fabric links, wherever possible. Zero-touch support is available for FortiLink mode over a layer-2 network and over a layer-3 network.
-
More tests have been added to the FortiSwitch recommendations to help optimize your network:
-
When a connected tier-1 multichassis link-aggregation group (MCLAG) peer group is detected and FortiOS detects a possible tier-2 MCLAG pair of switches, FortiOS recommends forming a tier-2 MCLAG.
-
When a connected tier-2 MCLAG peer group is detected and FortiOS detects a possible tier-3 MCLAG pair of switches, FortiOS recommends forming a tier-3 MCLAG.
-
-
You can now enable or disable the locking down of inter-switch links (ISLs) on a single FortiLink interface in the Edit FortiLink Interface page (WiFi & Switch Controller > FortiLink Interface).
-
The FortiOS switch controller now supports the synchronization of the FortiGate system interface description to the switch VLAN description (up to the first 63 characters of FortiSwitch VLAN description field in FortiOS). This allows a more flexible use of the Tunnel-Private-Group-Id RADIUS attribute.
-
The CLI commands for configuring Precision Time Protocol (PTP) transparent-clock mode have changed. FortiOS supports the previous CLI commands, as well as the new ones.
-
A new CLI command controls whether intra-VLAN traffic is blocked or allowed when the connection to the FortiGate device is lost. Before FortiOS 7.4.1, intra-VLAN traffic on the managed FortiSwitch units was blocked when the connection to the FortiGate device is lost.
-
Managed FortiSwitch VLANs can now mirror traffic on a client, and the FortiGate device will analyze the remote traffic.
-
Managed FortiSwitch units can now perform inter-VLAN routing. The FortiGate device can program a FortiSwitch unit to do the layer-3 routing of trusted traffic between specific VLANs.
-
When using FortiLink mode over a layer-3 network and DHCP discovery with DHCP option 138, the top FortiSwitch unit (with the _FlinkDhcpDisc_ trunk) will now automatically have a Spanning Tree Protocol (STP) priority of 24576, instead of an STP priority of 32768.
