The interface numbers change between stacking and non-stacking
cases due to the switch ID. So configurations saved for stacking are not
valid for non-stacking cases and vice versa.
Note:
If you choose stacking using the
stack
command from a
non-stacking case, and the configurations are already saved for
restoring the switch, it will rename the configuration file by
adding a suffix
_nonstack
and will not restore this file when the
switch reboots with stacking enabled.
Similarly, if you choose non-stacking using the
no stack
command
from the stacking case, and the configurations are already saved for
restoring the switch, it will rename the configuration file by adding a
suffix
_stack
and will not restore this file when the switch reboots
with stacking disabled.
Adding Stacking Members
Connect the stacked switches using stacking cables. For better
redundancy, connect the switches daisy-chained. This chain
connectivity helps to maintain stacking in case a single link or switch
fails.
Before connecting switches in stacking, make sure stacking is enabled
in all switches and that the switch identifier and priorities are all
configured properly.
There is no other specifical configuration required to add stacked
switches. If two stacking-enabled switches connect through stacking
cables, they form a stack.
Note:
Do not use the same switch ID for multiple switches on the
stack.
