Re: No internet connection in client side after replacing 3750 with 3850 switch

and also i have internet connection with my 3850 switch if i have my clients with firewall interface 172.16.2.252 as gateway. If only it is not working when i give the switch ip 172.16.2.1. with the below config.

 If you say any problem it is my old setting from 3750 switch is still in production environment and working with switch ip 172.16.2.1 as client gateway.

Re: No internet connection in client side after replacing 3750 with 3850 switch

when you turn on your 3850 and client has gateway with 172.16.2.1, they are able to ping 172.16.2.1 and 172.16.2.252?

Re: No internet connection in client side after replacing 3750 with 3850 switch

Hello

First of all you don’t need

ip route 192.168.100.0 255.255.255.0 172.16.2.252

As this subnet is on the core sw so why do you want to be routing that towards your Fw?

 

You have not confirmed if your clients able to ping the core switch svi addressing?

 

Do you have clients on both vlans 172&173 

 

If so then you should have your clients DG on vlan 172 and 173 point to the core svi interfaces

 

Lastly I see you vlan 172 subnet is a /22 (255.255.252.0) if this correct? 

 

Make sure you have the correct addressing applied and this is correct on the Fw/core and dhcp scopes 

 



kind regards
