Hi Adam,   sorry i missed your post.   at it's most simplistic, we have a MPLS line going into a site, the router is setup with HSRP but with one interface that will connect as a trunk port into the Meraki switch (obviously with the correct network settings), our ISP said the HSRP is sort of redundant in this simple instance and will activate if we enable a 2nd interface.   for the more advanced sites we have two lines coming in with two separate routers for our Private MPLS network, in this instance both interfaces are live on the switch ports but the default GW for us will be the virtual interface, which will of course be active/passive mode and will failover to either router in the event of a line failure.   during the troubleshooting i have tried to ping physical and virtual interfaces.   It feels so simple that it should work... but its not   thanks for your ongoing efforts Mark ...

Hi,   thanks for the clarification, confirmed the Vlan ID, Subnet and mask are correct on the Cisco router and the Meraki Vlan. It is on three switches i have tested across two sites (Networks), so must be a configuration issue but just cant see it.   I have posted the Cisco config on my Meraki support ticket and they will have access to my Meraki configuration so will update this post when we get to the bottom of it.   thanks for your help   Mark ...

Hi,   yes we was on a call for around 90 minutes trying to solve. the best i got was some entries in the ARP table showing the ISP router interface   I was reading up on HSRP and it looks like it needs Multicast to communicate to the other interface, the MS225 do not support Multicast but do support IGMP snooping shich i have enabled on the Vlan interface, still no luck. ...

Hi Adam,   Yes thats right, its Private but it does have a FW at the end (which is not commissioned yet)   The Default route for the Meraki devices is still the current ISP (another private MPLS) with a FW and we have obviously been using for some time.   Thanks Mark ... View more

oops, forgot to mention the Meraki devices are MS225-48 ... View more

Hi Shane,   i had a similar issue and was lucky that we had some acoustics engineers who worked for us, they took some measurements "in real world" in an open plan office with switches in a rack (they type you would put in a smaller offices), the link below will give you a good idea of the noise levels and what is considered an acceptable Db in an open office.   https://community.meraki.com/t5/Switching/Are-MS225-loud-fans-fixed/m-p/13765#M1137   hope it's useful   thanks Mark ...
