Introduction Most Dell switches today include a stacking feature that allows multiple switches to operate as a single unit. These stacks include up to twelve Dell Networking N4032/N4032F/N4064/N4064F switches in any combination, using up to four links between stack members. Any Ethernet port type on the front panel can be used in creating these links, including SFP+, QSFP+, and 10GbaseT. A single switch in the stack (known as the Master switch) manages all the units in the stack using a single IP address, which allows the user to access every port in the stack from this one address. This IP address is copied from the Master to the Standby when the Standby is created. If for any reason the Master fails, the Standby takes over as Master keeping the IP address of the stack the same. This allows continuous management of the stack. The new Master unit also continues to use the original Master unit’s MAC addresses, which helps to reduce disruptions to the network. When a failed
