New feature highlights Group Policy ACL on MS130 & MS150 Maximum MAC support in MAC Allowlists 802.1x limited access mode with pre-auth GPACL Local Status Page connectivity diagnostics enhancements Layer 2 multicast live tool Traffic Mirroring: RSPAN & VLAN Based SPAN Fixed issues Fixed a bug in Voice VLAN bypass, which caused Voice clients to get authenticated when re-authentication interval was configured Fixed an issue with MAB authorization that incorrectly placed clients in Critical Auth VLAN when suspend port bounce was enabled Resolved an issue that sometimes prevented SmartPort Automation rules using LLDP from correctly functioning with PoE+ clients on mGig ports Resolved a bug that sometimes caused clients to get stuck in an authentication loop after failing to pass an initial RADIUS authentication General known issues MS130 and MS150 switches may incorrectly remove or update SGT tags when no policy or VLAN mapping is defined. Until a firmware fix is available, correct SGT tags can be preserved by defining a policy for the SGT group in Adaptive Policies, and binding the SGT group to a VLAN using VLAN profiles. Clients authenticating via 802.1X with an access policy using hybrid authentication may not correctly log their RADIUS sessions In rare circumstances switches may experience uplink instability when IPv6 link-local addresses are enabled. If this issue is encountered it can be resolved by enabling IPv6 RA Guard to block ICMPv6 neighbor discovery messages. LACP links may take an extended time to come back up when the Active Member of a stack reboots Some switches may encounter an error, "incompatible configuration for attributes: allowed_vlans" when attempting to aggregate ports regardless of allowed VLANs configured in Dashboard Ms120 known issues Switches may fail to provide PoE power to legacy access points (always present) Cable tests may report incorrect cable lengths Ms225 known issues MS225 switches may infrequently stop forwarding client traffic until the switch is rebooted Ms350x known issues Switches may experience an unexpected reboot (present since MS 15) Ms355 known issues Switches in stack configuration may experience some ports failing to reconnect after a firmware upgrade Ms410 known issues Some MS410 switches may encounter alerts for fan failures that will eventually self-resolve Ms425 known issues In rare circumstances MS425 switches may encounter a software crash that results in a reboot Switches in stack configurations may experience high CPU utilization in multicast scenarios that may result in network instability
