FortiSwitch

Troubleshooting Troubleshooting FortiLink issues If the FortiGate does not establish the FortiLink connection with the FortiSwitch, perform the following troubleshooting checks. Check the FortiGate configuration To use the FortiGate GUI to check the FortiLink interface configuration: In Network > Interfaces, double-click the interface used for FortiLink. Ensure that Dedicated to FortiSwitch is set for this […]

Synchronizing the FortiGate unit with the managed FortiSwitch units You can synchronize the FortiGate unit with the managed FortiSwitch units to check for synchronization errors on each managed FortiSwitch unit. Use the following command to synchronize the full configuration of a FortiGate unit with the managed FortiSwitch unit: execute switch-controller trigger-config-sync <FortiSwitch_serial_number> Use one of […]

Configuring QoS with managed FortiSwitch units Quality of Service (QoS) provides the ability to set particular priorities for different applications, users, or data flows. NOTE: FortiGate does not support QoS for hard or soft switch ports. FortiSwitch supports the following QoS configuration capabilities: Mapping the IEEE 802.1p and Layer 3 QoS values (Differentiated Services and […]

Displaying port statistics Port statistics will be accessed using the following FortiSwitch CLI command: FG100D3G15804763 # diagnose switch-controller dump port-stats S124DP3X16000413 port8 S124DP3X16000413 0 : { “port8”:{ “tx-bytes”:823526672, “tx-packets”:1402390, FortiGate CLI support for FortiSwitch features (on non-FortiLink ports) “tx-ucast”:49047, “tx-mcast”:804545, “tx-bcast”:548798, “tx-errors”:0, “tx-drops”:3, “tx-oversize”:0, “rx-bytes”:13941793, “rx-packets”:160303, “rx-ucast”:148652, “rx-mcast”:7509, “rx-bcast”:4142, “rx-errors”:0, “rx-drops”:720, “rx-oversize”:0, “undersize”:0, “fragments”:0, “jabbers”:0, […]

Configuring storm control Storm control uses the data rate (packets/sec, default 500) of the link to measure traffic activity, preventing traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on a port. When the data rate exceeds the configured threshold, storm control drops excess traffic. You can configure the types […]

Configuring an MCLAG with managed FortiSwitch units A multichassis LAG (MCLAG) provides node-level redundancy by grouping two FortiSwitch models together so that they appear as a single switch on the network. If either switch fails, the MCLAG continues to function without any interruption, increasing network resiliency and eliminating the delays associated with the Spanning Tree […]

Configuring a link aggregation group (LAG) You can configure a link aggregation group (LAG) for non-FortiLink ports on a FortiSwitch. You cannot configure ports from different FortiSwitch units in one LAG. config switch-controller managed-switch edit <switch-id> config ports it <trunk name> set type trunk set mode < static | lacp > Link Aggregation mode set […]

FortiSwitch per-port device visibility In the FortiGate GUI, User & Device > Device List displays a list of devices attached to the FortiSwitch ports. For each device, the table displays the IP address of the device and the interface (FortiSwitch name and port). From the CLI, the following command displays information about the host devices: […]
