Trouble assigning IP to Catalyst 3560G after restart, home environment.

[ShashankSingh34569]

Hi There, 

I have a Catalyst 3560G switch I am using for a home environment and I cannot seem to assign an IP to it anymore... I bought this switch as I needed it for POE security cameras. Initially when I got the switch I configured it using Putty and assigned it a 192.168.1.250 IP. I could log into it and use the Cisco Network Assistant desktop app and manage it etc. Last night one of the cameras went down so I restarted the switch and the camera came back on however I cannot communicate with the Switch anymore. I tried to do initial configuration again but still no go. Here is what I am getting:

ciscoswitch>en
ciscoswitch#confg
ciscoswitch#conf
ciscoswitch#configure t
Enter configuration commands, one per line. End with CNTL/Z.
ciscoswitch(config)#int
ciscoswitch(config)#interface vlan 1
ciscoswitch(config-if)#ip addr
ciscoswitch(config-if)#ip address 192.168.1.250 255.255.255.0
192.168.1.0 overlaps with Vlan2
ciscoswitch(config-if)#

I keep getting the same error '192.168.1.0 overlaps with VLAN2' I don't have a Vlan 2. I even tried different IP address still no go... 

ciscoswitch#show vlan

I even tried to follow all the steps in this video here, as it worked the last time:

https://www.youtube.com/watch?v=IJWFwFL5Vzw&t=606s

I tried looking many places online to rectify this issue and none work...

I am not much savvy with Switch configurations yet. But am learning any help would be greatly appreciated.

Can you post the output of "192.168.1.0 overlaps with Vlan2"!

show ip interface brief - the command complaining that it overlaps with Vlan 2

Vlan1 192.168.1.250 YES manual administratively down down
Vlan2 192.168.1.99 YES NVRAM down down

So, there is a vlan 2. You can't assign IPs in the same segment to 2 different vlans. Try

config t

no int vlan 2

and than try assigning 192.168.1.250 to vlan1 again.

HI,

See the root cause:

Vlan1 192.168.1.250 YES manual administratively down down
Vlan2 192.168.1.99 YES NVRAM down down

It is not showing in your VLAN database because you missed creating a layer 2 VLAN and only created a layer SVI.

You can run below commands to resolve your issue:

config terminal

no interface vlan 2

!

it will delete the SVI VLAN 2 and you can reuse the subnet on SVI VLAN 1.

I was able to set it up state and assign an IP thanks! 

However now I seem to have locked my self out.. I thought I had put password 'cisco' but putty is not taking that....

Try to access the switch using a console cable if telnet is not working. If you can't access it via console neither, you would need to do a password recovery. See link for instruction on how to do that:
