Fixed issues
Fixed an issue that caused the Switch Port Packet Counter Live Tool to incorrectly underreport packet counts
Resolved an issue where multiple MS390s sharing a VLAN and data link could produce a multicast flood due to mismatched IGMP query interval and timeout settings
General known issues
Meraki native switches move LACP ports to an active forwarding state if configured. This can cause loops when connecting to an MS390 or other Catalyst switch unless the bundles are configured on the Catalyst side first. All Meraki native ports are configured in passive LACP mode so that loops do not occur between Meraki native switches (always present)
Ms390 known issues
MS390 stacks may fail to apply new configurations fetched from the network. This results from an issue with the NETCONF application, leading the system to revert to the previously stored configuration.
MS390s in stack configurations may experience high memory consumption, which can result in authentication failures. Reloading the active switch temporarily resolves the issue.
Packets between clients on separate VLANs may be stripped of their SGT when routed through an MS390
Stacks of 5 or more MS390s may experience a configuration mismatch when making multiple consecutive port configuration changes to several interfaces in a row
