New MS 15.4 beta firmware - general SFP fix and many fixes for MS390

Switch firmware versions MS 15.4 changelog

Alerts

  • HTTP proxy is no longer supported on MS 15+. Nodes that use HTTP proxy without any other means to connect to dashboard may fail to connect.
  • SecureConnect fails on MS355 series switches
  • MS390 ports are not disabled when configured to do so by dashboard
  • Moving or re-provisioning an MS390 stack in dashboard can cause at least one member to stay offline until rebooted (this only affects control plane traffic).
  • MS390 upgrades to this version will experience a full system reload
  • MS390s that have SecureConnect configured may lose uplink connectivity and would require a factory reset to recover
  • If SecureConnect is enabled on the network, MS390 access ports will not be a part of STP or receive broadcast traffic
  • MS390 upgrades to this version will result in a full system reload

Branch additions

  • IPv6 static routing support for MS390 series switches
  • Additional client analytics added for MS390 series switches
  • Meraki authentication support for MS390 series switches
  • Alternate Management Interface (AMI) support for MS390 series switches
  • UDLD support for MS390 series switches
  • Group policy ACL support for MS390 series switches
  • IPv6 management interface support
  • URL redirect support for MS390 series switches
  • UPoE (802.3bt) support for MS390 series switches
  • Netflow export for Adaptive Policy
  • Critical/failed authentication support for MS390 series switches
  • Multi-auth with voice VLAN bypass support
  • MAC flap detection support for MS390 series switches
  • Named VLAN support for MS120/125/210/225/250/350/355/390 series switches
  • Stack power is supported by default for MS390 series switches
  • Netflow support for MS390 series switches

Bug fixes

  • DHCP traffic is dropped on the voice VLAN if MAC allow list is configured
  • In rare instances, DAI inspection may fail to snoop DHCP transactions on stacks leading to those clients being in a blocked state
  • MS250 switches in rare instances could experience a crash when configuring LACP (predates MS 12)
  • MS210/225/250/350/355/410/425 series switches may be unable to initialize 1Gbps SFP modules. Current, only some MA-SFP-1GB-SX modules are in scope (present since MS 15.0)

MS390

  • Rebooting a MS390 switch in a stack via the UI will result in the entire stack rebooting
  • MS390 group policy ACL port ranges are not applied
  • MS390 ports are limited to the lowest link speed since boot if QoS is enabled
  • MS390 ports that have MAC allow list configured will not change between access and trunk once configured in dashboard

Known issues

  • If the voice VLAN authenticates before the data VLAN, the voice VLAN will stop working after the data VLAN authenticates (present since MS 14.28)
  • In rare circumstances, changes made to SVIs may result in connectivity loss for one or more SVIs until reboot (predates MS 12)
  • When applying an access policy to a port, voice VLAN clients will not be updated in the MAC table without bouncing the port (present since MS 14.28)
  • Connecting a stacking cable to a stack that is online may result in a stack member going offline (present since MS 12)
  • In rare instances, a stack member may go offline until rebooted (present since MS 12)
  • Networks containing a large number of switches may encounter issues saving changes on the Switch Settings page
  • Stack members may experience delays in updating their configuration for up to an hour after a config change (present since MS 9)
  • The "clone from" list may fail to load when cloning a switch in an organization with 1,000+ switches or networks
  • Broadcast types of traffic can leak into the Guest VLAN if a port that fails authentication has a voice VLAN configured, and dashboard has a Guest VLAN defined (present since MS 11)
  • AMI IP addresses do not send gratuitous ARP packets which can lead to packet loss if the AMI address has aged out in the network
  • Meraki authentication does not work with guest VLAN

MS120

  • Links being established on an MS120 can result in neighbouring ports to flap (present since MS 11)
  • In rare instances, MS120 series switches may have empty packet captures until they are rebooted
  • MS120s switch ports with MAB authentication may randomly de-authenticate clients. In order to resume client authentication on that port, a switch reboot is required (present since MS 12)

MS35X/4XX

  • Enabling Combined Power on MS350/355 switches results in events being logged once per minute (present since MS 11)
  • mGig switches will have an amber light for all physical ports that do not negotiate to the highest supported speed. Dashboard will continue showing a light green status for all ports above 100Mbps. For example, MS355 switch ports will incorrectly show an amber light for 1G, 2.5G, and 5G, but will show a green light for 10G.
  • MS350-24X and MS355 series switches do not negotiate UPoE over LLDP correctly (predates MS 10)
  • SecureConnect fails on MS355 series switches (present since MS 15)
  • Ports with an odd-numbered MTU value fail to initialize for MS120/125 series switches (predates MS 11)
  • When an SFP module is inserted/removed on MS420/425 series switches, BPDUs can be delayed leading to STP transitions in the network (predates MS 12)
  • MS350/450 series switches in a stack configuration will lose dashboard connectivity if a "Deny Any Any" ACL is added without having higher "Allow" rules in place for dashboard connectivity (predates MS 12)

MS390

  • Packet loss is observed when pinging the MS390 management IP (present since MS 12)
  • In rare circumstances, MS390 series switches may disconnect from dashboard until rebooted. Data plane traffic is not impacted unless RADIUS authentication is used (present since MS 14.28)
  • MS390 "Port Up/Down" events will be shown across all members
  • MS390 control plane may experience brief outages which will show as red lines on the connectivity bar in dashboard. These events do not affect data plane traffic.
  • MS390 series switches do not support loop detection
  • MS390 series switches do not support warm spare/VRRP
  • Moving or re-provisioning an MS390 stack in dashboard can cause at least one member to stay offline until rebooted (this only affects control plane traffic).
  • MS390 ports are not disabled when configured to do so by dashboard
  • MS390 series switches will go offline if a "Deny Any Any" ACL is added without having higher "Allow" rules in place for dashboard connectivity
  • MS390s that have SecureConnect configured may lose uplink connectivity and would require a factory reset to recover
  • If SecureConnect is enabled on the network, MS390 access ports will not be a part of STP or receive broadcast traffic

Cheers @cmr 

 

Love the fact that this is in there twice:

 

  • MS390 upgrades to this version will result in a full system reload

 

And what is with this one:

 

  • MS390s that have SecureConnect configured may lose uplink connectivity and would require a factory reset to recover

 

I think this should just state **"DON'T UPGRADE YOUR MS390's TO THIS VERSION"**

I'm not an employee of Cisco/Meraki. My posts are based on Meraki best practice and what has worked for me in the field.

A factory reset?  really.  This release should be blocked for MS390's give that.

Is the named vlan feature working for anyone? My MS120 is still showing IDs without any names =(

@Greenberet apparently it is only for RADIUS server use at the moment...

Will the MS390 ever work as designed?
