Dear all,

I need to configure 2 Cisco 9300x-48tx switches. I dont know what I did but right now whatever IP addresses I type on my laptop I access to switch. In attachment is the picture. Static routing is same like on old switch.

 - Have a sanity check by with ping to the intended switches , and verify correct address ,

I cant ping all IP addresses via cmd.

For example 172.20.156.24 is randomly typed address who I cant ping but can access GUI.

 

 - Do you have any background knowledge on the network topology and infrastructure  , perhaps there are intranet firewalls or similar leading you astray ?

Log in to each switch using a console cable with putty or Securecrt and post the output of "sh run"

Switch is not connected to anything, only connection switch has is with laptop. I think this is some setup on switch I accidentally did.

My static address on laptop is 192.168.201.50 /24 gateway 192.168.201.1.

When I change it to 200 network or any other network, I cant access to switch.

And on 201 network I can access to switch with almost any IP address.

 

Maybe you are using a /16 network configured on the switch.

post "sh run"

I already did some config on switch, I exported running config from switch. 

You have all these VLANs (see below) configured on the switch. So, if you put your laptop in any of these subnets, you can access the switch.

interface Vlan100
description Voice VLAN
ip address 192.168.200.1 255.255.255.0
!
interface Vlan101
description Data VLAN
ip address 192.168.201.1 255.255.255.0
!
interface Vlan103
description AD Mellongroup
ip address 192.168.203.1 255.255.255.0
!
interface Vlan104
description Fortigate VLAN
ip address 192.168.204.1 255.255.255.0
!
interface Vlan199
description VMware
ip address 192.168.199.1 255.255.255.0
!
interface Vlan255
description Camera VLAN
ip address 192.168.255.1 255.255.255.0

I know, but for some reason I can connect to switch only when my laptop IP is in VLAN101.

And when I connect to switch I can type almost any IP address in browser to access webui.

Also I cant access to switch when I am connected to TenGEth 1/0/2 altough VLAN101 is assigned to this port, but can access to TenGEth 1/0/24.

Perhaps console into that switch, and check the services and IP subnets/ACLs configured, perhaps a type while navigating on the GUI
