Yes, but only for slot 1, all vlans still exist, as is other configuration, only port assignment and port specific configuration actions need to be done.

Hi OscarK,

It means i have to reconfigure the current configuration in order to replace different module in Stacking. 

[OscarK]

From my knowlegde unconfigure slot 1 and reconfigure the ports and vlans on it is the only option to replace a slot with a different slot.

Hi all,

I will keep on update here. don't want to create another post. Since it's related to this stacking.

My question is How Can I Add Different Module to the current configured Module. Please see below for more detail.

I have uploaded the configuration to the Stack.
Current Configuration for Slot 1 is X250e-48t
and Now Replacement unit module is X250e-48p

if i use unconfigure slot 1.
Configuration will wipe out slot 1 config. i don't want to do it.

Please advice. How can i achieve without effecting the current config for port and vlan for slot 1 except changing from X250e-48t to X250e-48p. Thanks.

Slot-2 SW # unconfigure slot 1
This slot will be rebooted as part of this operation.

This will remove all port and vlan information for ports in this slot(1).
Any ports on this slot that are members of load share groups will be removed
from the load share group.
Continue ? (y/N)

configure slot 1 module X250e-48t
configure sys-recovery-level slot 1 reset
