No internet via 3750 to 3560... How to connect a 3560v2 to a 3750?

[BamBamm]

Here is the setup:

Router goes into the Cisco 3750...

the 3750 connects all the computers and servers in my house...

I am wanting to install POE security cameras around my property and since I have a Cisco 3560v2 w/POE just laying around, I was wanting to use it. I attached a working jumper going from port #32 of the 3750 into port #32 of the 3560v2. I attached another jumper from the independent security camera server into port #1 of the 3560v2. The camera server doesn't connect to the internet. I removed the jumper from port #1 of the 3560v2 and put it into port #19 on the 3750 and the server gets internet.

So, if running a jumper from the 3750 into the 3560 doesn't give that switch internet, how can I connect the 3560 to the same network as the 3750? I should also note that I do not know if the 3560 even works. It lights up and seems to work, but I don't know how to test the functionality of it.

There may be a configuration on the 3560. You are using very high end managed switches they can be configured to do lot of things and it would extremely common to have vlan settings on a switch. You generally do not use switches like this if you are going to use them as dumb level 2 devices so it is highly likely someone configured something on them.

Pretty much you are going to have to get into the 3560 and see what the configuration looks like. Worst case you are going to have to factory reset it and a switch is a pain to do that with.

I am assuming you have a router someplace since even though the devices can run as routers the main function they can not do is NAT.

Yes, I have an ASUS RT‑AC66U router.
I am not sure what you mean by "dumb level 2 devices".
I have 8 work servers attached to the Cisco 3750, with an additional 20 rackmount servers being used as a 3D render node.
The 3560 will have 30 POE security cameras attached to it. If you know a cheaper way to do all this, please let me know!

These switches can actually run as routers. Even if you run them only layer 2 most the time you would have vlans to keep different data types separate.

The dumb level 2 comment is based on you just thinking you can plug the switches together and it will in effect add more ports. They can work that way but nobody spends the money on these devices and does not use any of the features. This is how dumb unmanged switches work.

Still you can run them as dumb switches with a single vlan on all ports but you must configure it that way. If you delete the config I think it leaves all ports active on vlan 1 but I forget. To use the PoE function though you may have to enable this feature. Cisco is somewhat inconsistent in what the devices do with a default configuration.

I have installed the Cisco Network Assistant and Cable to a PC.
I will give it a shot and see what I come up with. Thank you for the help.

Been doing cisco for so many years and I have never used that program. I think it must actually have ip and be accessible to use it.

I always just use a console cable. If you need to reset it or do some of the very basic config you must do it via the console.

I am using the Console cable.
It told me to use the Cisco Network Assistant.
