Bug ID | Description |
---|---|
382518, 417024, 417073, 417099, 438441 | DHCP snooping and dynamic ARP inspection (DAI) do not work with private VLANs (PVLANs). |
414972 | IGMP snooping might not work correctly when used with 802.1x Dynamic VLAN functionality. |

When DHCP snooping is enabled on the FSR-112D-POE, the switched virtual interface (SVI) cannot get the IP address from the DHCP server Workarounds:

The time-domain reflectometer (TDR) function (cable diagnostics feature) reports unexpected values. Workaround: When using the cable diagnostics feature on a port (with the |
542031 | For the FS-5xx switches, the diagnose switch physical-ports led-flash command flashes only the SFP port LEDs, instead of all the port LEDs. |
548783 | Some models support setting the mirror destination to “internal.” This is intended only for debugging purposes and might prevent critical protocols from operating on ports being used as mirror sources. |
572052 |
Backup files from FortiSwitchOS 3.x that have 16-character-long passwords fail when restored on FortiSwitchOS 6.x. In FortiSwitchOS 6.x, file backups fail with passwords longer than 15 characters. Workaround: Use passwords with a maximum of 15 characters for FortiSwitchOS 3.x and 6.x. |
585550 | When packet sampling is enabled on an interface, packets that should be dropped by uRPF will be forwarded. |
606044/610149 | The results are inaccurate when running cable diagnostics on the FS-108E, FS-124E, FS-108E-POE, FS-108E-FPOE, FS-124E-POE, FS-124E-FPOE, FS-148E, and FS-148E-POE models. |
609375 | The FortiSwitchOS supports four priority levels (critical, high, medium, and low); however, The SNMP Power Ethernet MIB only supports three levels. To support the MIB, a power priority of medium is returned as low for the PoE MIB. |

When a dynamic LACP trunk has formed between switches in an MRP ring, the MRP ring cannot be closed. Deleting the dynamic LACP trunk does not fix this issue. MRP supports only physical ports and static trunks; MRP does not support dynamic LACP trunks. Workaround: Disable MRP and then re-enable MRP. |
