Stack to Stack Running Config Questions - 3850

[machine23]

I copied the running config from a production stack 3850 ( 2 switches ) to another 3850 stack on the test bench :-

1- The config did not apply the 2nd switch on test stack. - should I manually edit each g2/0/X interfaces ?

2- The IP routes did not apply & Gateway of last resort is not set.

Is it right in thinking even if the IP routing is enabled, The IP routes and gateways can only be configured if there are active connections?

thanks in advance.

Are they exactly same model? 

The process you did should work. You dont need to connect the switch to the network in order  to configure route and Gateway. 

 I dont know how you transferred the config but the right way to do is Export the running-config file and import in the other switch

Hi yes exact same model - firmware of the production is older 

copied from old switch to and applied by running command from usb to startup config and reloading.

Hello @machine23 

The switches are the same model, but discrepancies in behavior can arise due to differences in stack member numbering or how the configuration was transferred. While copying the configuration manually or using commands like copy running-config is common, ensure that the imported configuration matches the stack setup of the destination switches. For example, interface references like Gi2/0/x in the original stack need to correspond to the member numbers in the test stack.

As for IP routes and gateways, they can indeed be configured without the switch being connected to the network, provided IP routing is enabled. However, static routes won’t appear in the routing table unless the associated next-hop IP or interface is reachable.

Thanks for the reply - I will check the stack numbering- 

so is there any reason why it still says gateway of last resort not set even after issuing the ip route 0.0.0.0 0.0.0.0 <firewall ip >   ?
