Firmware

Hi All, 

 

So here is a weird one, curious to see if this happened to anyone else,  I had my MS switches on 12.27 and upgraded to 12.28.  As soon as I upgraded two of my servers went down (stopped passing traffic but showed online). Rebooting the switch and server did nothing, the only way to resolve was to revert back to 12.27.  

 

Meraki support did not really have an answer for me so I was curious to see if anyone ran into an issue like this?

Re: Firmware

If they were not accessible from the same VLAN, attached to the same stack, that suggests the switch L2 forwarding tables were not correct.  Usually, that is a rare event.  When it happens the entire stack has to be powered down at the same time and brought back up again.

 

Where the servers dual connected as a matter of interest?

 

Have you made the core switch stack the spanning-tree root?

Re: Firmware

Thanks I checked that and the only one that would fit my stack is the ms425 with the large L2 broadcast domain but it does not seem that large according to the traffic.

Re: Firmware

Were the servers accessible from within the same VLAN that they reside in?  Are these physical or virtual servers?  You mention switches, are they in a stack?

They were not accessible, it basically is a server controlling badge access for employees and it took down the whole badge system.  These are physical servers and yes the switches are in stacks I have a total of 9 stacks

Re: Firmware

A maximum of up to 8 switches can be stacked in a single stack recommended.
