Exchanging Stacking Members; Switching The Stacking Master - D-Link DXS-3250 Web/Installation Manual

•
Units toggle between Stacking Mode and Stand-alone Mode
Each time the system reboots, the Startup Configuration file in the Master unit is used to configure the stack. If a
stack member is removed from the stack, and then replaced with a unit with the same Unit ID, the stack member
is configured with the original device configuration. Only ports which are physically present are displayed in the D-
Link Web Management Interface home page, and can be configured through the web management system. Non-
present ports are configured through the CLI or SNMP interfaces.

Exchanging Stacking Members

If a stack member with the same Unit ID replaces an existing Unit ID with the same Unit ID, the previous device
configuration is applied to the inserted stack member. If the new inserted device has either more than or less ports
than the previous device, the relevant port configuration is applied to the new stack member.

Switching the Stacking Master

The Secondary Master replaces the Stacking Master if the following events occur:
•
The Stacking Master fails or is removed from the stack.
•
Links from the Stacking Master to the stacking members fails.
•
A soft switchover is performed with either via web interface or the CLI.
Switching between the Stacking Master and the Secondary Master results in a limited service loss. Any dynamic
tables are relearned if a failure occurs. The running configuration file is synchronized between Stacking Master
and the Secondary Master, and continues running on the Secondary Master.
