I am trying to stack 4 switch on a ring topology. All switch will be on layer 3

Vlan 1 will be on 192.168.21.X (ports 1-18)

Vlan 2 will be on 192.168.22.X (port 19-24)

Vlan 3 will be on 172.28.X.X (planning to make port 25-26)

We will have  2 sfp up links coming in and LACP must be enabled on these ports, whats the best way to connect these two up links? I am thinking on combining/link aggregation on ports(25) on switch 1 and 2 and then port 26 on switch 3 and 4. Assigning these to VLAN 3, then connect these 2 uplinks at each bonded ports.

Will this work? Any better ways to do this?

Also, Can traffic by default be able to communicate with each VLAN, since its on layer 3 ?

Any suggestions would be highly appreciated.

Hello everyone I would like to ask for the help of the community to solve a problem I've been having for some time. I have a Catalyst 3500XL series switch that doesn't have an iOS on it (purchased off eBay for my home lab) I've been trying to find an iOS for it here on the cisco website and have been very unlucky. I downloaded an iOS from a shady site that I haven't tried putting it on the switch as of yet mostly because I can't get past the flash_int command, the switch just freezes / locks up after that command and I don't know what else to do. Is there a place for old legacy iOS where I can get an image for this router?

Thank You!!!

I didn't find the right solution from the Internet.

Hi

I'd like vlan 102 to be the native vlan instaead of vlan 1. What do I need to do to make this happen. My thoughts were to shutdown vlan1 and add vlan102 as an interface. Am I right?
