Step 7: Save the running configuration.

Option 3: Congure the Cisco Catalyst 3750-X platform

Step 1: When there are multiple switches configured in a stack, one of the switches controls the operation of the

stack. This switch is called the stack master.

When three or more switches are configured as a stack, configure the stack master switch functionality on a

switch that does not have uplinks configured.

switch [switch number] priority 15

If you configure stack master switch priority on Cisco 3750-X switch stack, a single reload is required to force

the stack master to operate on the switch that you configured with the highest priority. Reload the switch stack

after all of your configuration is complete for this entire “Configuring the Distribution Layer” process.

Step 2: By default, the newly active stack master switch assigns a new stack MAC address when the stack

master switch fails. This new MAC address assignment can cause the network to reconverge because LACP and

many other protocols rely on the stack MAC address and must restart. As such, you should use the stack-mac

persistent timer 0 command to ensure that the original master MAC address remains the stack MAC address

after a failure.
