New MS 15.14 beta firmware - more MS390 fixes but several remaining stacking bugs

Switch firmware versions MS 15.14 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.
  • Moving or re-provisioning an MS390 stack in dashboard can cause the management plane of at least one member to stay offline until rebooted (present since MS 15.0)
  • MS390 upgrades to this version will result in a full system reload
  • MS390 series switches can only downgrade to MS 12 with an incremental step to MS 14
  • MS390s with a Group Policy ACL containing spaces or non-alphanumeric characters results in ports being initialized with incorrect configurations of trunk, native VLAN 1, until the system finishes booting

Branch additions

  • STP anomaly detection support for MS390 series switches
  • 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
  • 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 series switches
  • Stack power is supported by default for MS390 series switches
  • Netflow and Encrypted Traffic Analytics (ETA) support for MS390s

Bug fixes

  • ARP Table Not Updated Upon Receipt of Gratuitous ARP Request
  • The local status page does not indicate to allow port 443 upstream for Nextunnel capable devices when they fail to connect to dashboard

MS390

  • MS390s with IPv6 only management will fail to connect to dashboard
  • In rare instances, MS390 stacks can experience a management plane restart
  • In rare instances, MS390 stack members can fail to perform an upgrade resulting in an errored state
  • MS390 upgrades can intermittently fail resulting in an upgrade loop
  • Powering off a MS390 member in a stack doesn't result in the member showing as offline in dashboard (present since MS 15)
  • MS390 switches do not generate event logs for guest or critical authentication, RADIUS server timeouts, or EAP status
  • In rare instances, MS390 ports will fail to initialize correctly on boot resulting in one or more ports remaining offline

Known issues

  • IGMP querier is enabled on all VLANs resulting in IGMP messages being sent every 125 seconds. Layer 2 switches use the management IP as the querier address. (always present)
  • Networks containing a large number of switches may encounter issues saving changes on the Switch Settings page
  • In rare instances, RADIUS accounting sessions may not be removed after a client disconnects with an EAPoL logoff message (present since MS 11)
  • 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

Stacking

  • LACP bundles configured across stack members experience brief outages when a stack member goes offline and again when it comes online (present since MS 10)
  • Stack members may experience delays in updating their configuration for up to an hour after a config change (present since MS 9)
  • Stack ports may fail to initialize properly upon reboot. A subsequent reboot of the switch would be needed (present since MS 14)
  • Connecting a stacking cable to a stack that is online may result in a stack member going offline (present since MS 12)
  • Switch stacks will learn MAC addresses from ports in the STP blocking state which can trigger a constant flood of MAC flaps in the event log
  • LACP bundles spanning multiple stack members can result in a temporary loop if one of the stack members is rebooted (present since MS 11)

MS12X

  • In rare instances, MS120 series switches may have empty packet captures until they are rebooted
  • Links being established on an MS120 can result in neighboring ports to flap (present since MS 11)
  • MS120 series switches in extremely rare instances will experience reboots every few minutes (present since MS 11)
  • Ports with an odd-numbered MTU value fail to initialize for MS120/125 series switches (predates MS 11)

MS35X/42X

  • 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)
  • 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)
  • Enabling Combined Power on MS350/355 switches results in events being logged once per minute (present since 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)

MS390

  • MS390 management plane may encounter infrequent restarts (always present)
  • MS390 series switches in rare instances disconnect from dashboard until rebooted (present since MS 14.33)
  • MS390s in rare circumstances will experience a full system restart (preset since MS 14)
  • When the MS390 management plane experiences a restart, LACP flapping can occur
  • MS390s that receive incorrectly flooded CDP packets may incorrectly report VLAN mismatches and SFP port information (present since MS 12)
  • MS390 "Port Up/Down" events will be shown across all members
  • MS390 stacks may send frequent DHCP requests despite having a valid static IP address, which can result in IP flapping (present since MS 14)
  • 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 the management plane of at least one member to stay offline until rebooted (present since MS 15.0)
  • Rebooting an MS390 switch in a stack via the UI will result in the entire stack rebooting
  • MS390s with a Group Policy ACL containing spaces or non-alphanumeric characters results in ports being initialized with incorrect configurations of trunk, native VLAN 1, until the system finishes booting

In regard to the IPv6 static routing support:

Where do we configure the appropriate IPv6 networks and addresses once the Upgrade to 15.18 is installed?

 

Our MS390 is on 15.18, but I can't find any option in the dashboard ..
