3850 stack - replacing one member

[abhdivak]

Hello All,

I have a 3850 stack, we RMA one of the member because it was faulty. I copied the IOS image via connecting ethernet cable between the new switch with one of the stack member. Now upgraded the new switch(Separately, not connected to stack). Before connect this new switch to stack, do i need to remove the all configurations which i made on new switch ?  If yes, how can do that? Is write erase command enough ?

Regards,

Abhijith

The IOS for the 3650/3850 is unique.  The IOS can either be installed using the "install" method or the "bundle" method (read Install Versus Bundle Mode).

Before connect this new switch to stack, do i need to remove the all configurations which i made on new switch ?

All configuration, including VLAN.DAT file, must be removed.

How to remove all the configuration from new switch ??

Command:  wr erase

I need to give write erase command on new switch and for delete VLAN info , need to apply command delete flash:/vlan.dat right ?

Command:  delete /f /r flash:vlan.dat

Hello Leo,

What is the difference between the commands delete flash:/vlan.dat and delete /f /r flash:vlan.dat ?

What is the difference between the commands delete flash:/vlan.dat and delete /f /r flash:vlan.dat ?

Enter the command "delete flash:vlan.dat" and see what happens.   Hint:  You won't immediately delete the file.

Hello,

As per my knowledge, delete flash:/vlan.dat command ask for confirmation and delete /f /r flash:vlan.dat won't. Is that the only difference ?

Thanks,
