I am re-iping the exiting network from 10.35.X.X to 10.21.X.X.
This is not my decision of re-iping . This decision was taken before I join the company.
The actual network is like that.
We have the ISP cable from the demark goes to a 3650 which is stacked to another 3650 and these 3650 are connected to 2 Meraki MX84 one is HA.
There are couple of vlans on 3650 with DHCP and exceptions/ Everything is working fine with 10.35.X.X.
Now before I start doing the re-iping I have been given a new Meraki MX100 and a new Cisco Switch 9300 and a new ISP connection.
I have tried to understand the configurations by looking at the actual configurations of the 3650 and MX 84 .
My questions are as follows:
(1)Just looking at the cable I can see that my ISP cable is connected to port 1 on my 3650 and the configurations on that port are.
description INTERNET
switchport access vlan 24
switchport mode access
no cdp enable
spanning-tree portfast
I tried to do the same on the Cisco 9300.Configured same vlans and name but different Ip address and different exceptions but could not get it working.
When I connect a laptop to the switch 9300 , I am getting a new ip address of 10.21.X.X but cannot go to internet.
So my first question is should the ISP line go to the switch or to the Meraki port where it is written Internet.
I want to have the Switch 9300 connected to the Meraki and the ISP connected to the Meraki or Switch (I am not sure how it should be) but want to make sure that I have internet on ports on the Switch and I can connect a cisco VOIP phone to have it registered.
Thanks in advance

we are not sure how your network topology
if the internet connection terminated to internet router, that internet router connected to 9300
internet modem---9300----MX100 is the right way doing.
10.21.X.X - to go this IP address to internet you need to NAT in internet router ?
post router and switch configuration of your exiting one so we can suggest for the migration to 9300 and re-ip.

Hello
I would assume the reason why you have the 3650 in between the MX's is that you only have one ISP connected to (vlan 24 port gig1/0/1- as such I would have expected both the MX's also vlan 24, I do see two other ports gig1/0/-2 -3 in vlan 24 so are these being used for the HA resiliency?
However those ports (gig1/0/-2 -3) have descriptions as ALLSTREAM, can you tell us what this is or is it just a ghost entry.
Port gig1/0/11 is in vlan 10 (10.21.64.0/21) which looks like its the meraki inside lan facing port on the same broadcast network as various other devices including a WLC, is this is separate WLC or a meraki wireless appliance?

I don't see any reference to the 10.31.x.x subnet so where does this L3 subnet reside and also what 10.21.x.x. subnet are you wanting to change this addressing to again I am assume this would be 10.21.64.0/21 (vlan 10) or it is 10.21.0.0/21 (vlan2)

Where does the 9300 come into play with this design, are you wanting to migrate from the 3650 stack to the 9300
