If it does rename them it will probably affect the vlans.  
Hi, Sometime when configure some Dell 6224 I've encontered issues with interface's names. When I boot the switch ( stand-alone) it marks itself as switch n°2 of the stack and so all interfaces are configured as 2g/N.   I've tryed to delete the startup-configuration and reboot the switch but the issue persist. It is marked always as 2° switch of the stack that not exist.   Do you know how solve this issue?? Thanks
