If I set one IP l3 interface on my swith it works fine. I can connect to this IP no problem. However, as soon as I created another L3-interface IP I lost all connections to this switch. What is wrong? Can someone help please?
Hi tri.nguyen .
I hope you're doing great.
I have faced similar behavior caused by IP addressing conflict, please check the default gateway and its address to make sure there are no duplicate address or overlapping.
Please also check the routing if by any chance you have static, go ahead and check that the return route is properly configured.
Keep me posted.
