Cisco Systems 3120 manual Setting the Installed Switch Module As the Stack Master

Chapter 2 Switch Installation

Using the Onboard Administrator to Assign an IP Address to the Switch Module and Running Express Setup

Step 5 Click Enable in the Daylight Savings Time field to enable this feature.

Step 6 In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch module by using the CLI. If you enable Telnet access, you must enter a Telnet password.

Note If you plan to create a switch stack, enable Telnet access so that you can use the CLI to set this switch to the highest priority. See the “Planning and Creating a Switch Stack” section on page 2-13for more information about creating a switch stack.

Step 7 In the Telnet Password field, enter a password. The Telnet password can be from 1 to 25 alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. In the Confirm Telnet Password field, re-enter the Telnet password.

Step 8 In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP). Enable SNMP only if you plan to manage switches by using CiscoWorks 2000 or another SNMP-based network-management system.

Step 9 If you enable SNMP, you must enter a community string in the SNMP Read Community field, the SNMP Write Community field, or both. SNMP community strings authenticate access to MIB objects. Embedded spaces are not allowed in SNMP community strings. When you set the SNMP read community, you can access SNMP information, but you cannot modify it. When you set the SNMP write community, you can both access and modify SNMP information.

Step 10 In the System Contact field, enter the name of the person who is responsible for the switch module. In the System Location field, enter the wiring closet, floor, or building where the switch module is located.

Step 11 Click Submit to save your settings, or click Cancel to clear your settings.

You can close this window.

To install additional switch modules, repeat the steps in the “Installing the Switch Module in the Blade Enclosure” section on page 2-6through the “Using the Onboard Administrator to Assign an IP Address to the Switch Module and Running Express Setup” section on page 2-9.

Setting the Installed Switch Module As the Stack Master

If you plan to create a switch stack, we recommend that you set the switch module that you first configured as the stack master. To do this, you must assign the highest priority value to this switch module. To assign a priority value after you have installed and initially configured the first switch module, follow these steps:

Step 1 Launch a Telnet session by connecting directly to the switch through its console port, or by using the Onboard Administrator:

On the left side of the Onboard Administrator, click + next to Interconnect Bays to expand it, then click

+next to the name of the switch you want to set as the switch master. Click Management Console to open the device manager for the switch, and if prompted, enter the user name and password for the switch. Under Contents, choose Maintenance > Telnet.

	Step 2	Enter enable.
	Step 3	Enter configure terminal.
	Step 4	Enter switch 1 priority 15.
