Alerts
- MS390 upgrades from MS 14.10 or later will result in minimal impact to client traffic
- MS390 client authentication may fail closed if RADIUS server passes unsupported AVPs
- Auth session state on RADIUS server may be stale following an MS390 CoA update until RADIUS Accounting is supported
- MS210/225/250 switches cannot forward IPv6 Router Advertisement and Neighbor Solicitation packets when flood unknown multicast is disabled (has always been true)
Bug fixes
- MAC flap events can be created when a MAC is relearned on the same port following a flush or age-out
- MS390 stacks of 4 or more may experience instability
- Downgrading MS390 switches to older firmware can take longer than expected
Known issues
- Non-MS390 switch stacks using Dynamic ARP Inspection can block ARP packets which should actually be permitted
- MS390 stack members may not report client-level detail
- MS390 series switches Max MTU is limited to 9198 bytes
- MS390 series switches will not display packet details in the DHCP Servers page
- MS390 series switches do not support the 'next-server' or 'bootfile' parameters in DHCP messages
- Rebooting a single switch in an MS390 stack will reboot the entire stack
- LLDP frames from MS390 series switches will use a single system name instead of the Dashboard given name
- MS390 series switches will not display the advertising router ID for OSPF
- MS390 series switches with OSPF enabled will default to an IP MTU of 1500 bytes on every OSPF enabled interface
- MS390 series switches do not support the multicast routing livetool
- MS390 series switches do not support tagged traffic bypass for voice on ports with a Multi-Auth access policy
- Dynamic VLAN assignment from a RADIUS server on MS390 series switches must already be an allowed VLAN on the port for it to function
