MS 12.x release train available

[cmr]

Additions are a process to deal with MAC flap and loops but the ARP entry expiring on L3 is still a known issue...

Switch firmware versions MS 12.8 changelog

Alerts

• MS210/225/250 switches cannot forward IPv6 Router Advertisement and Neighbor Solicitation packets when flood unknown multicast is disabled (has always been true)

Additions

• Support for MS390 Series Switches
• Loop Detection on MS210/225/250/350/355/410/420/425/450 series switches
• MAC Flap Detection on MS210/225/250/350/355/410/420/425/450 series switches

Bug fixes

• Username Received in RADIUS Access-Accept can be sent with different formatting in RADIUS Accounting-Request
• Port mirroring does not work on MS390 series switches

Known issues

• 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
• Stacked MS390 series switches do not report traffic/client analytics correctly in all cases
• 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
• MS390 series switches may not display link state on links at mGig speeds (2.5G, 5G)
• MS390 series switches do not currently support the following features: VRRP, SM Sentry, Syslog server, SNMP, Traceroute, IPv6 connectivity to dashboard, Meraki Auth, URL Redirection, MAC Whitelisting, RADIUS Testing, RADIUS Accounting, RADIUS CoA, QoS, Power Supply State, PoE power status/usage, Loop Detection, UDLD, MAC Flap Detection
• ARP entry on L3 switch can expire despite still being in use (predates MS 10.x)
• SM Sentry does not support Windows based clients (predates MS 10.x)
• MS425 series switches do not forward frames larger than 9416 bytes (predates MS 10.x)
• MS350-24X and MS355 series switches do not negotiate UPoE over LLDP correctly (predates MS 10.x)

Other

• Various performance and stability improvements

I can´t see any advantages or technical inventions for a major release step from 11.x to 12.x

Best guess is: "Support for MS390 Series Switches"

[PhilipDAth]

If I wanted stability in my network I would not be deploying an MS390.  The release notes give a hint to the number of bugs with supporting this new platform.  I bet there are a lot more this early on.

What, you want to be able to use SNMP, syslog, etc?

I'm waiting for the next train to my destination.
