Configuring and Bringing Up a Stack

After you attach the cables in a stack of Aggregators, follow these steps to

configure and bring up the stack:

1 Connect the terminal to the console port on an Aggregator. Enter the

following commands to access the CLI and configure the base-module

ports for stacking mode:

Password: *****

FTOS> enable

FTOS# configure

FTOS(conf)# stack-unit 0 iom-mode stack

Where

stack-unit 0

configuration of a switch.

2 Save the stacking configuration on the 40GbE ports:

FTOS# write memory

3 Repeat Steps 1 and 2 on each Aggregator in the stack by entering the

stack-unit 0 iom-mode stack

4 Reboot each Aggregator by entering the reload command in EXEC

Privilege mode:

FTOS# reload

If the stacked switches all reboot at approximately the same time, the

Aggregator with the highest MAC address is automatically elected as the

master switch. The Aggregator with the next highest MAC address is

elected as standby master.

Tip: You can ensure that a stacked switch becomes the master by rebooting

the switch first, and waiting for it to come up before rebooting the second

switch in the stack.

The Status LED on the Aggregator that is elected as the master switch is

blue. Perform VLAN and other software configuration for the stack by

connecting to the console port on the master unit.

To determine which switch is the stack master, you can also enter the show

system command at the terminal.

defines the default stack-unit number in the initial

command and saving the configuration.
