How about we have a home/amateur local networking general?
I recently acquired a Cisco Catalyst 3560G Ethernet switch, and I'd like to set it up as part of my home network. I've gone through the Cisco quick start guide, connected my desktop and whatnot yet I still can't get a connection to the internet. I have it (the switch) plugged with a CAT6 to my slave router with the default gateway as (my master router) and in the same subnet mask as the master[spoiler][/spoiler]. Am I missing a step? Sorry if this is a really simple question.


Turn off the switch.
Connect to the switch via a console cable:
Turn on the switch
During boot if some automated wizard starts to ask you for something, say no.
Once it seems to have finished booting press enter, and then you should see a 'switch>' prompt.

At that point it should work and you can disconnect the console cable.(Unless you wnat to configure the switch)

If it still won't work... Go back to the switch console(reconnect the console cable).
Switch> en
Switch# sh run
Switch# sh start

And shouw us the output of both the sh run and sh start commands here in this thread.

Let's go full CCNA mode!

Also, is it a second hand router? Did the previous owner wipe his old configurations?


>Also, is it a second hand router? Did the previous owner wipe his old configurations?
Second hand from a hospital, they were upgrading their equipment and I got it for cheap. I would assume the configs were wiped already, and I think the express setup wipes the config too. The bundle did not come with a console cable unfortunately. Do you have any suggestions on where I can get one or which one I should get?


Your local computer hardware shop should have one.
Never heard of that express setup, what did it do and how?


I just read through the Cisco QuickStart guide for the switch, and it included going through the express setup. It includes holding down the mode button for three seconds then seven, then connecting a machine to the switch and configuring it through a web interface. The guide can be found here: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/hardware/quick/guide/3560gsg_08.html


Oh, the 3560 is a layer 3 switch(that's obvious from the instructions). That's a special beast. I haven't don much with those. I admit that I haven't really ever done anything with layer 3 switches.
The way I see it all you need is a layer 2 switch. So perhaps we should be thinking into ways on how to make it basically a layer 2 switch.

FYI layer 3 switches are something like hybrids between routers and switches.

Well, do the stuff I said in my earlier post and then we will have more to go on.(if that is convenient for you)


I don't have a console cable, but the switch supports telnet administration so I'll set that up for the time being. Once I've got that up I'll see how the commands go and post any outputs if it doesn't.


OK. Do it that way. But I am afraid that when/if we need to wipe the configuration we will lose telnet.


Had to put the outputs in a paste since they were too large.


... and I forgot to post the paste.


IDK why does it want you to set up a non-default vlan and trunking for simple switching?

If you actually go to the shop for the cable, and the shopkeeep isn't sure what a console cable is, ask him for a cisco rollover cable:


>IDK why does it want you to set up a non-default vlan and trunking for simple switching?
I don't understand.


It does stuff that's IMO unneccessary. Either that or it's because of my limited knowledge of L3 switches. Perhaps we should wait for other people with cisco knowledge to join.

I am however of the opinion that we nuke the config and see if it would work normally with an empty config. It usually does.


So, you are try to configure the connection to be this?
Desktop - Switch - S Router - M Router - Internet


Yes, assuming "Internet" implies a modem and a ISP.
