Planning and Creating a Switch Stack

Step 5 At the prompt, press Return.

Step 6 Enter end.

Step 7 Enter copy running-configuration startup-configuration to save this setting.

Step 8 At the prompt, press Return.

Step 9 To verify that this switch is set as the switch master, enter the show switch user EXEC command.

For more information about creating switch stacks, see the “Planning and Creating a Switch Stack” section on page 2-13.

Refreshing the PC IP Address

After you complete Express Setup, you should refresh the PC IP address:

•For a dynamically assigned IP address, disconnect the PC from the switch module, and reconnect the PC to the network. The network DHCP server assigns a new IP address to the PC.

•For a statically assigned IP address, change it to the previously configured IP address.

Planning and Creating a Switch Stack

A switch stack is a set of up to nine stacking-capable switch modules that are connected through their StackWise Plus ports. One of the switches controls the operation of the stack and is called the stack master. The stack master and the other switches in the stack are stack members. Layer 2 and Layer 3 protocols present the entire switch stack as a single entity to the network. Stacking is optional.

When switch modules are not stacked, each acts as a standalone switch. For general concepts and procedures to manage switch stacks, see the switch module software configuration guide and command reference on Cisco.com.

Caution The Cisco Catalyst Blade Switch 3120 for HP does not support switch stacks with other types of blade switches as members. Combining the Cisco Catalyst Blade Switch 3120 for HP with other types of blade switches in a switch stack might cause the switch to work improperly or to fail.

Before you connect the switch modules in a stack, keep in mind these stacking guidelines:

•You should install the stack master switch module and run the initial setup program on that switch module before you connect the StackWise Plus cables to other stack members. We recommend that you assign the highest priority value to the switch module that you prefer to be the stack master. This ensures that the switch is re-elected as stack master if a re-election occurs. As you add new switch modules to the stack, they automatically become stack members.

To assign a priority value through the Onboard Administrator after you have installed and initially configured the first switch module, see the “Setting the Installed Switch Module As the Stack Master” section on page 2-12.

•When you connect the StackWise Plus cables and create a stack, you can communicate with the master switch internal Ethernet management port (Fa0) port, but not the Fa0 ports of the member switches. Only one Fa0 interface can be active, and that interface is the one on the active stack master.
