MS 18.1.4 RC Out, Only Fixes for MS150s

[Mloraditch]

Important fixes for MS150s! and some new known issues

Important notes

• This firmware release only includes updates for MS150 switches. All other MS switches on MS 18.1.4 will run firmware identical to MS 18.1.3.1.

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

Ms150 fixed issues

• Fixed a bug that caused MS150 switches to incorrectly remove or update SGT tags when no policy or VLAN mapping was defined
• Resolved an issue that caused some SFP and QSFP modules to experience intermittent flapping
• Fixed a bug that caused some MS150 switches in stack configurations to lose connectivity while reporting redundant uplinks as blocked
• Resolved a bug that caused some 48 port MS150 switches connected to MX gateways to experience reductions in uplink throughput if the uplink was connected to any port in the 41-48 range

Known issues

General known issues

• MS130 and MS150 switches may not properly display IPv6 RA packets in dashboard packet captures
• 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.
• 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

Ms130 known issues

• 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.
• MS130X mGig ports may fail to establish a link when both sides are forced to 100 Mbps full-duplex. If either side of the connection uses auto-negotiation the link will be established normally

Ms150 known issues

• When a stacking cable is disconnected from MS150 switches in stack configurations the disconnected port will incorrectly continue to be marked as connected while the still-connected stacking port will incorrectly be marked as disconnected
• In rare circumstances MS150 switches in stack configurations may experience a software crash following a stack member reboot, resulting in an unexpected active member election
• In rare circumstances MS150 switches in stack configurations may experience a software crash following a stack member reboot, resulting in a multicast storm and possible interruption of connectivity until the stack has been rebooted
• MS150 switches incorrectly advertise 60-watt PoE++ on all ports. PoE++ is only available on mGig ports; ports 17-24 on MS150 24MP-4X switches, and ports 33-48 on MS150 48MP-4x switches.
• In certain circumstances, MS150 switches using cross-stack LACP may place a port into a discarding state after a stack member reboot, with the affected port failing to transmit LACPDUs until the LAG group is recreated.
• MS150 switches may intermittently negotiate USB-C Ethernet adapters at 10 Mbps half-duplex instead of the expected speed for the switchport, requiring a physical reseat to correct the issue.

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
