Layer 3 cisco configuration

[uzrack2015]

Please I need help of the CLI configuration guide for my layer 3 switch. 

I want to create 3 vlans with dhcp, I also have a tplink router to give internet to the switch. I need the CLI configurations. Thank you

TPLINK you need to route back to switch and make sure also add to NAT those IP address using in the LAN

depends on the switch model below config should work for you  ( there are lot document available in the google if you like to use it)

basic config :

config t

VLAN 10,20,30
ip dhcp excluded-address 192.168.10.0 192.168.10.5
ip dhcp pool VLAN10
default-router 192.168.10.1
dns-server 8.8.8.8
network 192.168.10.0 255.255.255.0

ip dhcp excluded-address 192.168.20.0 192.168.20.5
ip dhcp pool VLAN20
default-router 192.168.20.1
dns-server 8.8.8.8
network 192.168.20.0 255.255.255.0

ip dhcp excluded-address 192.168.30.0 192.168.30.5
ip dhcp pool VLAN30
default-router 192.168.30.1
dns-server 8.8.8.8
network 192.168.30.0 255.255.255.0

interface vlan 10
ip address 192.168.10.1 255.255.255.0
no shutdown

interface vlan 20
ip address 192.168.20.1 255.255.255.0
no shutdown

interface vlan 30
ip address 192.168.30.1 255.255.255.0
no shutdown

Interface Fa0/0
no switchport
ip address x.x.x.x 255.255.255.0 ( TPLINK Lan IP address)
no shutdown

ip routing

ip route 0.0.0.0 0.0.0.0 x.x.x.1 (TP Link Router IP)

end device connecting to different VLAN

Interface Fa0/1
switchport mode access
switchport access vlan 10

switchport access vlan 20
no shutdown

Interface Fa0/3
switchport mode access

I implemented this, but when I pinged the different vlan ip addresses, it did not reply. 

There must be something am missing.

I implemented this, but when I pinged the different vlan ip addresses, it did not reply. 

what IP to what IP you pinging ? did the VLAN SVI up (show ip interface brief)

did the PC able to ping gateway IP's ?

Does the PC have Firewalls ?

Do you IP arp on the switch in related to the PC not pinging ?

There must be something am missing. 

sure we hear you, we can not see what configured there what missing, you need to provide show run - show ip arp, show ip interface brief (output for us to know what is missing ?)

Ok will do

Hello,

post the output of:

show ip int brief

from the switch.

If the switch supports it the output of show interface status might be helpful.
