In the perfect setup yes, but what I have to work with now is the best we could afford. Even getting a MS320 as core instead of "just" another MS220 was taxing the budget.   At the time I had the choise to get this setup, get a setup based entirely on Cisco SG300 series or a setup based entirely on D-Link.  (The two D-Link had to be added later as we changed the workspace for the teachers ahead of scheduled expansion, I plan to get them changed to Meraki as well)   The way the net is build all switches are dual role as both access and core switches, at least the three larger ones (A1, B1 and B2) ...

Port 12 and 13 on the MX (the Access VLan 16), how are they connected to the MS, and how are those ports on the MS configured ?   Port 1 on the MS, is that the only one connected to the MX and if so on what port on the MX? ... View more

Thanks Chris   The main part of the network are the Meraki switches, the two D-Link (and a third in my office) are not "mission critical" so they get redundant if I feel like it, if not then no big deal. Was just curious if I was wrong about the possibility to create redundant setup like the one I wanted, makes me happy to see I was on the right track.   And yes, all switches are on the same IP subnet. ...

Thanks for the reply, I have tried to pin out the setup a bit more.   Present setup: switch-port: A1-25 SFP - D1-10 SFP backbone A1-26 SFP - C1-10 SFP backbone A1-27 SFP - B1-24 SFP backbone A1-28 SFP - B2-24 SFP backbone C1-8 Cat6 - C2-8 Cat6 D1-8 Cat6 - D2-8 Cat6 Redundant setup by adding: switch-port: B1-23 SFP - B2-23 SFP (or just using Cat6 as they are mounted in the same rack) B1-22 SFP - C1-9 SFP (or C2-9 SFP if it supports stp/rstp proper) B2-22 SFP - D1-9 SFP (or D2-9 SFP if it supports stp/rstp proper) B1-21 + B2-21 SFP's are kept as spare for now, or get fiber to the ESXi host in that rack 😉 The STP are set up with: A1 as 0-root B1 - 4096 B2 - 8192 D1 - 12288 C1 - 24576 RSTP enabled All switches are 1Gb except the 10Gb SFP+ on the MS320 A1 - MS320-24P B1 + B2 - MS220-24P C1 + D1 - MS220-8P C2 is a D-Link DGS-1210-10P only used for two printers and a single workstation D2 is a D-link DGS-1210-10P only used for 5 dockingstations if the teachers need cable and a bigger monitor   Not sure if I need to learn a bit about OSPF to get it to work though.   regards Søren ...
