There is a Typo mistake in IP address i guess ( or am i misgendering this wrong ?)

On L3 Switch

Create a VLAN

config t

Vlan 10,20,30,99

!

Interface vlan 99

ip address 192.168.99.254 255.255.255.0

!

Interface vlan 10

ip address 192.168.XX.254 255.255.255.0  (if this /23 correct the subnet and IP)

!

Interface vlan 20

ip address 192.168.XX.254 255.255.255.0  (if this /24 correct the subnet and IP)

I

interface vlan 30

ip address 192.168.XX.254 255.255.255.0  (if this /24 correct the subnet and IP)

!

ip routing




On the Sw connected interface




interface fas x/x

switchport mode trunk




On the each switch side same  access switch

config t

Vlan 10,20,30,99

!

Interface vlan 99

ip address 192.168.99.253 255.255.255.0

!

!

interface fas x/x

switchport mode trunk

!




where the devices connected configured as per the device role




Interface fas x/x     (student)

switchport mode access

switchport access vlan 10




Interface fas x/x     (Teacher)

switchport mode access

switchport access vlan 20




Interface fas x/x     (Admin)

switchport mode access

switchport access vlan 30

[nonfko]

im not sure i understand this part 

interface fas x/x

switchport mode trunk

!




where the devices connected configured as per the device role




Interface fas x/x     (student)

switchport mode access

switchport access vlan 10




Interface fas x/x     (Teacher)

This on no L3 Switch side config :

i have changed the ip addresses from 192.168.99.2 to 192.168.99.254 and now i seem to be able to ping all pc's!

without even doing anything else

[balaji.bandi]

Sure ..may we not have any visibility on what is configured on the devices. so that was my suggestion based on the information.

glad you able to resolve the issue or made a config as per your requirement.

i have one more question, what about the vlan 99 am i supposed to assign vlan 99 to the 3 switches like i did with the laptops?

[balaji.bandi]

If you like to manage all Switches, then Switch required some Layer 3 SVI, so extend the VLAN to Switches, and create 1 spare IP address to each switch to connect using SSH.
