Also, can you ping 8.8.8.8.from the router with the source being the LAN interface ?

?

yes I am able to ping 8.8.8.8 source GigabitEthernet0/1 from router, but after changes on switch I am not getting ip for client, client getting apipa

Hello,

 

delete the entire Vlan 10 interface and the default gateway and use Vlan 1 for management instead:

 

interface Vlan10
description ** DATA VLAN **
ip address 192.168.10.2 255.255.255.0
ip helper-address 192.168.10.1
!
ip default-gateway 192.168.10.1

any another solution

Hello,

 

what does your network look like, do you have more or just that one switch ? I would default the config of the switch and start from scratch. I don't now what is missing, but configuring a switch should almost take no time at all...

I have only one router and one switch, Let me know what to do now

I assume that you are not on a live network ?

 

wr erase

 

to delete the configuration of the switch, then reload it, that will give you the switch with just the default configuration. Then configure just the link to the router and check if you get connectivity.

 

It is almost impossible to take you through all the steps remotely, do you have somebody available at the site who can assist you ?

I am available on site

wr erase

 

and then reload the switch, all ports will be in the default Vlan 1.

 

interface GigabitEthernet1/0/48
switchport mode access
!
interface GigabitEthernet1/1/2
des ***connected to dc router ***
switchport trunk encapsulation dot1q
switchport mode trunk

ok tring this, should I keep Ip routing as earlier ip routing was used for the same when link was live

No, don't enable ip routing, as that will turn your switch into a router...

ok will update u after reconfiguring in a while

Hi

As Reza mentioned could you please share the config, it could be DNS configured on the computer or NAT or default route misconfiguration.
