If the Backup Master has been hot removed, a new Backup Master will be chosen through the election
process previously described. Switches in the stack will clear the configurations of the unit removed, and
dynamically learned databases, such as ARP, will be cleared as well. Then the Backup Master will begin
backing up the Primary Master when the database synchronization has been completed by the stack.
If the Primary Master is removed, the Backup Master will assume the Primary Master's role and a new
Backup Master will be chosen using the election process. Switches in the stack will clear the
configurations of the unit removed, and dynamically learned databases, such as ARP, will be cleared as
well. The new Primary Master will inherit the MAC and IP address of the previous Primary Master to avoid
conflict within the stack and the network itself.
If both the Primary Master and the Backup Master are removed, the election process is immediately
processed, and a new Primary Master and Backup Master are determined. Switches in the stack will clear
the configurations of the units removed, and dynamically learned databases, such as ARP, will be cleared
as well. Static switch configurations still remain in the database of the remaining switches in the stack and
those functions will not be affected.
NOTE: If there is a Box ID conflict when the stack is in the discovery phase, the device will
enter a special standalone topology mode. Users can only get device information,
configure Box IDs, save and reboot. All stacking ports will be disabled and an error
message will be produced on the local console port of each device in the stack. Users
must reconfigure Box IDs and reboot the stack.
