CHAPTER 3 Using Your Hub Software This chapter describes procedures for configuring the Cisco Micro Hub, and contains the following sections: • • • Preparing for Configuration Configuring the Hub Command Summary Preparing for Configuration To configure any Cisco Micro Hubs in a stack, the stack must include at least one Micro Hub 1503.
Preparing for Configuration Connection Using Telnet If the hub is correctly connected to a network, you can access the hub by using Telnet from anywhere on that network and can use the configuration program to communicate with the hub. Before making a Telnet connection to the hub, you must configure the hub with a valid IP address, subnet mask, and default gateway using the configuration program.
Command Conventions Command Conventions This section describes some things you might need to know before using the commands to configure the hub. If you are familiar with these conventions, you can skip this section. • Enter commands by typing the text of the command at the configuration prompt and then pressing the Return key.
Preparing for Configuration • You can abbreviate commands to the fewest letters that make them unique. For example, for the show history command, you can enter: Hub> show his • Certain commands display multiple screens with this prompt between screens: --More-- Press the space bar to see more output from the command or press Return to display the next line. Press any other key to return to the prompt.
Forgot Your Password? The field can contain from 0 to 80 uppercase and lowercase alphanumeric characters. Spaces are not allowed. The first character cannot be a number. Passwords are case sensitive. An example of a valid password is mypassword1. Forgot Your Password? If you forget the password that provides access to administrator-level commands or if you forget the password required for Telnet sessions, you can bypass the password requirement and set a new password.
Configuring the Hub Step 7 The following message appears, confirming that your new passwords have been accepted: Administrator and telnet passwords are modified. Welcome to Cisco hub model 150x Configuring the Hub This section describes basic hub configuration. Before you configure a Micro Hub 1503, have the following information available: • IP address and IP subnet mask that you will assign to the hub if you are accessing the configuration program using Telnet or SNMP.
Hub ID Numbers Here are two rules that determine hub ID numbers in a stack of hubs: 1 The lowest hub ID number in a stack (1) is always assigned to the hub with another hub connected to its OUT port and with no hub connected to its IN port. 2 The highest hub ID number in a stack (any number from 2 to 5) is always assigned to the hub with no hub connected to its OUT port and with another hub connected to its IN port. Figure 3-1 illustrates these rules.
Configuring the Hub Configuring the hub takes place in three major steps: 1 Entering Administrator Mode 2 Configuring IP and SNMP Parameters 3 Configuring the SNMP Management Station All of the commands used in the configuration steps are fully explained in the section “Command Summary” later in this chapter.
Configuring IP and SNMP Parameters Configuring IP and SNMP Parameters The illustration below shows the network that is being configured in this section: Figure 3-2 Server Example Network PC PC PC E0 Router A E1 SNMP network management station S6280 Micro Hub 1503 Note The network addresses used in the steps below are examples only; they will not work for your network. You should substitute them with the IP addresses that apply to your network devices.
Configuring the Hub Step 3 Use the ip trap-manager command to configure the IP address of the SNMP management station: Hub# ip trap-manager 1 172.16.20.2 Basic IP and SNMP configuration is now complete. To return to guest mode, enter exit.
