Stacking S-Series Switches | 1021

The S-Series has three MAC addressees: the chassis MAC, interface MAC, and null interface MAC. All 
interfaces in the stack use the interface MAC address of the management unit (stack manager), and the 
chassis MAC for the stack is the master’s chassis MAC. The stack continues to use the master’s chassis 
MAC address even after a failover. The MAC address is not refreshed until the stack is reloaded and a 
different unit becomes the stack manager.

 

stack (excluding the new unit) reloads.

Note: If the removed management unit is brought up as a standalone unit or as part of a different stack, 
there is a possibility of MAC address collisions.
