This chapter describes the major system administration tasks of the Cisco ESSE. It contains the following major sections:
You can connect to the Cisco ESSE web interface to perform a limited set of administrative tasks using the GUI, but all functions are available using the CLI. You can connect to the Cisco ESSE to use the CLI in any of the following ways:
If you are connected to the Cisco ESSE via the web, enter a valid username and password in the login screen to log in, and click the Logout button to log out.
If you are connected to the Cisco ESSE via the CLI, enter a valid username and password at the login prompt to log in, and enter the exit command to log out.
All GUI users have the same access privileges, while CLI users have tiered access. To create user accounts, you must be logged in as the admin user, and then create accounts using the username command. For more information on creating and administering user accounts using the CLI, see the "username" section.
 |
Tip Telnet access is disabled by default. If you want to allow telnet access to the CLI, use the firewall CLI command as described in the "firewall" section. |
You should back up the Cisco ESSE essential files at regular intervals to an FTP server. Before attempting to back up or restore your Cisco ESSE, make sure the username and password is valid on the target system, that the target directory exists and has the proper permissions for the username and password, and that the system allows FTP. Backing up the Cisco ESSE will preserve all configuration, user, device, and log information. Table 4-1 lists some of the more important file locations.
| Description | location |
|---|---|
/opt/CSCOets/NAS/webapps/cesse1105/WEB-INF/classes/ |
|
To back up your Cisco ESSE, follow these steps:
Step 2 Select Administration > BackUp/Restore.
Step 3 If you have not yet configured the backup location, do so by clicking the Configure button and entering the required information.
Step 4 Click the Backup button.
To restore your Cisco ESSE, follow these steps:
Step 2 Select Administration > BackUp/Restore.
Step 3 Click the Restore button.
Step 4 Select the image you want to restore from the drop-down menu and click Continue.
Step 5 A window appears displaying the image you will be restoring. If the information is correct, click OK.
You can also back up and restore your Cisco ESSE by using the following CLI commands:
 |
Note The system will automatically reboot after a user runs the restore command from either the CLI or the GUI. |
You can shut down the Cisco ESSE using either the web interface or the CLI. Rebooting the system starts the management services installed on the system, even if they were stopped prior to the reboot.
To restart the Cisco ESSE using the web interface, select Administration > Restart. Click Yes in the dialog box that appears. The Cisco ESSE will restart.
To shut down the Cisco ESSE using the CLI, enter the shutdown command before powering down the Cisco ESSE. If you power down the Cisco ESSE without entering this command, you might disable the system.
To reboot the system using the CLI, enter the reload command. The login prompt appears when the reboot is complete.
To erase the system configuration and reboot the system using the CLI, enter the erase config command. After the system reboots you must reconfigure the system using the setup program, as described in the "Configuring the Cisco ESSE" section.
For more information about these commands, see these sections:
The Cisco ESSE uses Universal Coordinated Time (UTC) for the time and date. The Cisco ESSE uses the client's local time to display the time and date when connected via the web interface. It uses UTC to display the time and date when connected via Telnet or a console, or when you are viewing log files.
You can set and maintain the system date and time using either of these two methods:
To display the system time, enter the show clock command. For more information, see the "show clock" section.
NTP is the recommended method for configuring time and date on the system. If your network uses NTP to set the date and time on devices, enter the following command in the CLI to designate an NTP server the system should use to set the system clock:
Where ip-address is the IP address of an NTP server.
For more information, see the "ntp server" section.
If you disable NTP, set the system clock to UTC manually as described in the "Setting Date and Time Manually" section. If you do not set the system clock manually after disabling NTP, the system clock might become inaccurate when the system is rebooted.
If your network does not use NTP to set the system time on devices and the time is not set correctly, set the date and time to UTC manually by entering the following command at the CLI:
hh:mm:ss is the current time (for example, 13:32:00)
month is the current month (for example, January, February)
day is the day of the month (for example, 31)
year is the current year (for example, 2001)
For more information, see the "clock" section.
The Cisco ESSE uses 10/100 Mbps Ethernet connectors. The Ethernet 0 interface is connected to the IP management network and is configured when the Cisco ESSE is configured. The Ethernet 1 interface is connected to the Layer 2 network. To enable or change an additional interface configuration, enter the interface command in the CLI. For instructions about using the interface command, see the "interface" section.
Any Cisco ESSE Ethernet port can be individually configured to allow connections via the following protocols:
To enable CDP on an individual Ethernet port, use the cdp command. For more information, see the "cdp" section. To disable any of the other protocols listed above on an individual Ethernet port, use the firewall command. For more information about the firewall command, including a detailed example of its use, see the "firewall" section.
The Cisco ESSE allows you to administer all management services at once. All commands that affect management services affect all of them at once; the logs that collect services information collect information about all of them. You will need to log in with the username admin to use these services.
You can stop and restart the management services if the system is not responding correctly to a management application. This should cause the services to reset and function properly again. Management services are restarted automatically when you reboot, but you will have to log in again after the system reboots.
To stop management services, enter the following command at the CLI:
To start management services, enter the following command at the CLI:
To view management services status, enter the following command at the CLI:
For more information about the services command, see the "services" section.
To view system information, use the show commands, such as show clock and show process. For more information on the show commands, see "Command Reference."
The Cisco ESSE has an operating system image and a default system configuration (hereafter collectively called the maintenance image) stored in Flash memory. You can use the maintenance image to boot the system to perform some system administration tasks and disaster recovery.
While the system is running from the maintenance image, you can run only the following commands: reload, erase config, and fsck.
For information about these commands, see the "Maintenance Image Commands" section.
While the maintenance image is running, you can do the following tasks, which you cannot do when the system is booted from the disk:
As a security measure, you can boot from the maintenance image only while connected to the system console. To boot from the maintenance image, follow these steps:
Step 2 Reboot the system by doing one of the following:
Step 3 When the LILO boot: prompt appears, press the Tab key.
Step 4 When the boot: prompt appears, enter CiscoBreR.
Step 5 After you complete all necessary tasks, reboot the system by entering the reload command and allow the system to boot from the disk (the default boot order).
If you cannot log in to the system because you cannot remember the administrator account names or passwords, you can recover by booting from the maintenance image, erasing the existing configuration from Flash memory, and reconfiguring the system using the setup program.
To recover from the loss of all administrator passwords, perform the following steps:
Step 2 Enter the erase config command to erase the system configuration. The system reboots.
Step 3 Allow the system to boot from disk (the default boot order).
Step 4 Configure the system from the setup program, as described in the "Configuring the Cisco ESSE" section.
Step 5 After the system reboots, reconfigure the Cisco ESSE by following the steps outlined in the "Installing the Cisco ESSE" section.
This section describes tasks you should perform when installing a replacement
Cisco ESSE (a new unit intended to replace an existing unit), to make the transition as easy as possible. These tasks are in addition to the installation and configuration processes described in "Installing and Configuring the Cisco ESSE."
Before removing the old Cisco ESSE, perform the following steps:
Step 2 Record the configuration manually.
Step 3 Back up the old Cisco ESSE. See the "Backing Up and Restoring Your Cisco ESSE" section for details.
Step 4 Enter the shutdown command.
Step 5 Power down and remove the old system.
To install the replacement Cisco ESSE, perform the following steps:
For details, see the following sections:
Step 2 Run the setup program.
For details, see the "Configuring the Cisco ESSE" section.
Step 3 Using the configuration settings that you recorded from the old system, answer the setup program prompts.
Step 4 Restore the information saved when you backed up the old system. For more information, see the "Backing Up and Restoring Your Cisco ESSE" section.
A recovery CD is included with your Cisco ESSE. With this CD in the Cisco ESSE CD-ROM drive you can perform two functions: you can reimage the Cisco ESSE, or you can boot from the rescue image. When the recovery CD is inserted into the CD-ROM drive of a Windows NT 4.0 or Windows 2000 computer, it starts a web server application and also creates a repository of software images for use on the Cisco ESSE. Initially, the repository will only contain the image shipped with the Cisco ESSE, and future upgrades will be found on the CCO web site.
Use the Cisco ESSE recovery CD to reimage the Cisco ESSE if necessary. Reimaging will destroy all data and install a new image. To reimage your Cisco ESSE, follow these steps:
Step 2 Log in using the username admin and enter the password created when the Cisco ESSE was configured.
Step 3 Put the recovery CD in the Cisco ESSE CD-ROM drive. For the location of the CD-ROM, see the "Front-Panel Features" section.
Step 4 Enter the reload command. The Cisco ESSE will reboot. For more information on the reload command, see the "reload" section.
Step 5 At the Do you wish to continue (yes/[no]/rescue): prompt, enter yes. If you do not want to reimage your Cisco ESSE, enter rescue. For more information about the rescue image, see "Rescue Image" section.
Step 6 When the Cisco ESSE ejects the recovery CD, remove it.
Step 7 At the Do you wish to reload and start the install?(yes/[no]): prompt, enter yes.
The Cisco ESSE reboots and is reimaged.
The rescue image is equivalent to the maintenance image, but is accessible via the recovery CD. If the maintenance image is unavailable or is not working, you can use the rescue image to boot the system to perform some system administration tasks and disaster recovery. You can use the same maintenance image commands while the system is running the Rescue image: reload, erase config, and fsck. For more information about the uses of the Rescue image, see the "Using the Maintenance Image" section.
To boot from the Rescue image, perform the following steps:
Step 2 Log in as the user admin. The password for the user admin was created when the Cisco ESSE was configured.
Step 3 Put the recovery CD in the Cisco ESSE CD-ROM drive. For the location of the CD-ROM, see the "Front-Panel Features" section.
Step 4 Enter the reload command. The Cisco ESSE will reboot. For more information on the reload command, see the "reload" section.
Step 5 At the Do you wish to continue (yes/[no]/rescue): prompt, enter rescue. The Cisco ESSE will boot from the Rescue image.
A repository warehouses available software for the Cisco ESSE. A repository can serve as the repository for one or more Cisco ESSEs. The remote repository can be a Windows NT or Windows 2000 server. You may configure a repository before or after installing the Cisco ESSE.
If you are using a Windows NT or Windows 2000 server as a repository, before you define the remote repository using the GUI, you must create the repository using the recovery CD included with the Cisco ESSE.
Step 2 Insert the recovery CD included with the Cisco ESSE.
Step 3 A browser window will automatically open.
Step 4 Follow the instructions in the browser window to set up the remote repository.
