Access the Command-Line Interface over the console Port

Make the basic power and console cable connections described in Connecting Serial Console and Mgmt Ports and power on the GigaVUE TA Series node.

Start a terminal application on the PC. Common terminal applications include TeraTerm, PuTTY, and Hyperterminal.

Select the COM port connected to the console cable attached to the console port. For example, COM1.

Configure the port settings for the console connection as follows:

•

Bits per second – 115,200

•

Data bits – 8

•

Parity – None

•

Stop bits – 1

•

Flow control – None

Note: On the GigaVUE-TA10 and GigaVUE-TA40, you can change the console port’s speed if you need to by using the procedure in Changing the Console Port’s Speed.

If you experience problems connecting to a Cisco Terminal Server, try changing the console Port’s speed to 9600 bps using the procedure in Changing the Console Port’s Speed and reconnecting.

Note: The GigaVUE-TA100, GigaVUE-TA100-CXP, GigaVUE-TA200 support only a fixed serial baud rate of 115,200bps.

Setting COM Port Properties for the Console Connection

Start the terminal connection. You may need to press Enter a few times before you see the login: prompt.

Useradmin

Passwordadmin123A!

Starting in software version 4.7, the configuration jump-start automatically starts and forces a password change.

The system administrator must change the password on the default admin account through the jump-start script. The default password (admin123A!) is no longer allowed. Refer to Run the Jump-Start Script for details.

A password must meet the following standards:

•

include 8-30 characters

•

include at least one numeral

•

include at least one upper case letter

•

include at least one lower case letter

•

include at least one special character (for example, !, @, #, $, %, ^, &, or * –, ASCII 0x21, 0x2F, 0x3A, 0x40, 0x5B, 0x5F, 0x7B, 0x7E)

At the Admin password? prompt in the jump-start script, enter a new password that meets the standards, then confirm the password.

Changing the Console Port’s Speed

By default, the console port operates at 115,200bps. You can change the speed of the console port to 9600bps on the GigaVUE-TA10 and GigaVUE-TA40 with the serial baudrate <9600 | 115200> command.

Keep in mind the following points when changing the console port’s speed:

•

After changing the console port’s speed, you must save the active configuration and reload the system for the change to take effect.

•

After setting the console port to 9600bps, the u-boot output will appear correctly on the connected serial console. However, you will need to press the spacebar once or twice for the CLI login prompt to appear.

•

You can use the show serial baudrate command to view the currently configured console port speed.

Run the Jump-Start Script

Gigamon provides the GigaVUE nodes with a jump-start script that walks you through the process of configuring basic settings. Run this script as follows:

Switch to Config mode.

There are three command entry modes, each with increasingly powerful rights – Standard, Enable, and Config. The jump-start script is only available in config mode:

Type en <Enter> to switch to Enable mode.

The system prompt changes from [hostname] > to [hostname] #.

Type config t <Enter> to switch to Config mode.

The system prompt changes from [hostname] # to [hostname] (config) #.

Reset the terminal settings to match the current window with the following command:

terminal resize

Type config jump-start to run the jump-start script.

Follow the jump-start script’s prompts to set each of the settings listed below.

Note: If you change your mind about a particular setting, you’ll have a chance to change it at the end of the script.

Hostname

The hostname appears in the system prompt and is used to identify the chassis in SNMP traps.

Management Port Network Settings

Use either DHCP or specify a static IP address and netmask. If you do not use DHCP, you are prompted to configure the following additional options:

• Default Gateway

Supply the IP address of the default gateway for the node.

• DNS Server

Supply the IP address of the DNS server for the node. Note that a valid DNS server is required for successful use of TACACS+.

• Domain Name

Supply the domain name for the node (for example,

mycompany.com).

Default Gateway

Supply the IP address of the default gateway for the system.

DNS Server

Supply the IP address of the DNS server for the system. Note that a valid DNS server is required for successful use of TACACS+.

Domain Name

Supply the domain name for the system (for example, mycompany.com).

Enable IPv6?

You can enable the use of IPv6 for the management port. IPv6 is used in addition to IPv4 if you enable this option. If you enable the IPv6 you have the option of enabling IPv6 autoconfiguration or specifying a static address.

Security Settings

Enable the following security settings:

•

secure cryptography mode

•

secure passwords mode

•

minimum password length

Refer to the GigaVUE-OS-CLI Reference Guide for information on security.

Admin Password

The password for the admin account must be changed to a non-default password.

Cluster Enable?

Enable cluster support if this node will be a part of a cluster of connected GigaVUE nodes. If you enable cluster support, the jump-start script prompts you to supply the Cluster ID, Cluster Name, and Cluster Mgmt Virtual IP Address. You can join an existing cluster by supplying values that match existing settings.

If clustering is enabled, you will not be prompted for a box ID in the next step.

Refer to the GigaVUE-OS-CLI Reference Guide for information on setting up a cluster.

Note: Connecting a Traffic Aggregator to a cluster requires a license.

Box ID for the Node

Supply a numerical box ID for the node. This box ID is used to identify network/tool ports in the node – the format is box ID/ slot ID/port ID.

You will be prompted for a box ID only if clustering was not enabled in the previous step.

Review your settings. You can change a setting by specifying its listed line number and re-entering the setting.

When you are satisfied with your settings, exit the script as prompted. The system automatically saves your settings.

Restart the system with the reload command.

Need to Change Any Settings?

If you need to change any of the settings you made in the jump-start script, you can either run the script again or change individual settings using the following commands in the Configure command mode:

•

Use the hostname command to change the system’s hostname.

•

Use the interface eth0 command to reconfigure or fine-tune Mgmt port settings, including basic IP settings (DHCP or static address and subnet mask) and physical parameters (duplex, MTU, and speed).

•

Use the ip command to change the default gateway, DNS server, and domain name.

•

You can also use the username admin password <password> command to change the admin user’s password. Refer to Changing the admin Account Password.

•

Use the chassis box-id command to change the system’s box-id.

Refer to Completing the Initial Setup for a quick summary of the available GigaVUE commands for TA Series nodes.
