Factory reset Catalyst 3560

Hello Experts

I have tried to factory reset my 3560, but it simply won't be posible..

...and I have followed the many guides on the web, and in this forum, but with no luck...

Thanks in advance

no need to do flash_int, that is when you in switc mode (aka ROMMON mode).  your switch looks like have default config now; no hostname, no IPs set, no user name and password, usually mean default settings loaded.  check for vlans, those are kept in flash:vlan.dat.  which u can delete that file or delete each vlan or just override vlans with your own. Check content of flash storage for files and dates.

copy and paste output from show run and we can tell you if your switch has default settings but I think it is set to "empty" default settings. 

there is no factory reset for switch per sey.

You switch has basic config like any other new switch shipped

some how you see files are .renamed, if you like you can delete them and reboot the device.

you only to your commands you try to excute when you are in switch: not switch#

Hi BB.

Allright, so it has basic settings, so far so good..

I now have tried to delete the renamed vlan.dat,  I get this error trying..:

delete vlan:

You made a little error during the sequence.
When you have the following message:
Delete filename [vlan.data.renamed] ==> Just type enter
In your case, switch tries to remove the file named "y" that does not exist.

Hi, JELA.

Great.. My fault.. Now the Vlan is gone...

I have reloaded the switch and wired my laptop to LAN 1, but there is still no internet connection through the switch.

SYST and STAT  ... and LAN1 is lightning green

I get this (Windows 10)

Once you removed all the config, the device like brand new device come from cisco.

Connect the console cable to switch and start comnfiguring from Console,how you do new device to get back to as your expected to work,

Hello
From which device do expect your windows pc to be allocated an ip address, Do you have router maybe from the ISP connected to this switch?, IF so and this rtr is going provide ip address allocation , network translation and internet access then your need to activate two ports on the switch for your pc and the isp router.

conf t

interface range fa0/1 -2
switchport
switchport host
no shut
end

Hello Paul.

My setup is like this. ..and I haven't changed any settings in my fiber-router from my ISP. (Dynamic IP)

I thought the switch would work without any changes, when I have done the default reset.. But I have to do more "work" to get it working I guess..

As per the diagram it will work in default VLAN, but make sure your ports are in no shutdown mode

connect to console  cable, 

go to the port where the device connected or make port range

here is command 

>en

#config t

interface range fas 0/1-8

no shutdown

!

interface Gi 0/1

no shutdown

!

end

!

Connect the DSL cable to Gi 0/1

connect your PC to any of ther Ethernet port

The PC should get IP address from DSL Modem

if this is still not working, do 2 test confirm

1. if you connect PC to directly to DSL Modem is the internet working ?

2. if working, please post switch configuration "show run" after modfiication above guided steps.

2. show interface status.

Hello

as per the switch configuration i posted earlier just plug the pc and isp modem in to switch ports fa0/1 and fa0/2 and you should gain connectivity.

If you don't obtain that connection post the output of the switch 

sh ip int brief

Hello Paul.

Waauv.. Thanks.. I have now gained internet.. But I'm a little bit confused, why I shouldn't use the port beside the SFP port?

Another thing is, that it seems there's a bandwidth limit restriction on the port...

My ISP provides 1000/1000mbit but my speed is limited to10mbit.

Maybe I'm still having some old settings, in the switch..

Many thanks in advance.

check the port connected to fastethernet port what is the speed negotiation. post show interface fast x/x (x/x where the internet port connected)

after connecting same connection to Gi 0/1 also post show inter gig 0/1 , i am suspecting this could be speed negotiation.
