Switch firmware versions MS 17.1.1 changelog

Ms12x important notes

If DAI is enabled prior to upgrading the network to MS 16, ensure that trusted ports and/or DAI-allow lists are configured prior to upgrading to avoid potential network outages.

Ms420 important notes

Devices configured for this version will run MS 15.22

New feature highlights

DOM (Digital Optical Monitoring)
Intelligent Capture
RSPAN and VLAN Based SPAN
SmartPorts

New ms130x feature highlights

Adaptive Policy on MS130X/R models

Fixed issues

Fixed an issue that caused multicast routing to fail on switches in stack configurations after disruptions to link aggregation
Fixed an issue that caused unexpected LACP discarding states after aggregate links were restarted or reconnected
Fixed an issue that prevented MS130R switches from setting half-duplex mode on switch ports running at 10Mbps/10Mbps HDX
Fixed an issue that prevented some switches in stack configurations from successfully routing multicast traffic
Resolved an issue that prevented successful 802.3bt LLDP negotiation on MS355
Resolved an issue where the option to disable client uplink sampling was only functioning for the default aggregation group (AGGR/0). This feature now works correctly across all aggregation groups.

General known issues

RADIUS communications may not recover after an initial failure when Critical Auth is enabled
Stack port configurations may become isolated or changed upon multiple flaps or when disabled
Switches move LACP ports to an active forwarding state if configured. This can cause loops when connecting to an MS390 or other Catalyst switches unless the bundles are configured on the MS390/Catalyst switches first. All non-catalyst ports are configured in passive LACP mode so that loops do not occur between Meraki switches (always present)

Ms120 known issues

Switches may fail to provide PoE power to legacy access points (always present)

Ms12x known issues

ms120/125s may fail to forward link-local multicast [224.0.0.x] traffic when 'Flood unknown multicast traffic' is disabled

Ms130 known issues

In rare circumstances MS130s may experience management plane congestion that results in UDLD alerts and STP transitions

Ms210 known issues

Stack ports have an orange LED instead of green (present since MS 11)

Ms250 known issues

Multicast traffic may not be properly forwarded between switches in stack configurations when the source and receiver are either in different VLANs or different stacks

Ms2xx/35x/4xx known issues

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

Ms35x known issues

Enabling Auto-stacking on MS350s may remove existing L3 SVIs
In rare instances, stack ports fail to initialize after an upgrade (always present)
Incorrect SFP port mappings may disrupt SFP functionality
Switches may experience an unexpected reboot (present since MS 15)
UPoE does not negotiate over LLDP correctly (always present)
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.

Ms425 known issues

MS425 stacks may become unresponsive under high load
MS425s in stack configurations may periodically trigger New DHCP Server alerts that include mismatched VLANs/subnets

Ms4xx known issues

When an SFP module is inserted/removed, BPDUs can be delayed leading to STP transitions in the network (predates MS 12)

I wish they had put links to documentation of the new features in the release notes (like they have sometime done on major MR updates).

I cant seem to find the documentation of those features anywhere.

Hi @thomasthomsen here is something:

https://documentation.meraki.com/MS/Other_Topics/Digital_Optical_Monitoring

RSPAN and Smart ports are in this latest video and don't seem to be documented yet...

Thanks. - I did not see the last update vid.

But Im just old fashioned, I really like ( Enjoy almost 🙂 ) documentation on released features 🙂

thomasthomsen

I was hoping so much to actually test the new Port Profiles (them now being org. wide, and that has been a major wish from some of my customers for a while), but alas, that feature did not appear after the upgrade.

So Im guessing not everything is made public yet.

Hope this fix whatever issues 16.9 had. Nothing visible but everything worked terrible at least. Apple HomeKit to

mention one of the things. The firmware that has been the worst ever on my count
