Troubleshooting


This chapter describes some common problems that occur while setting up the Cisco NAM Virtual Blade.

Licensing Issues


Note Cisco NAM Virtual Blade software provides a 60-day evaluation license. If you do not have a license for the WAAS device, you can purchase a license by going to the following URL: http://www.cisco.com/go/license. See Licensing, page 1-2 for more information.


If the NAM VB license is not set, you will not be able to start the NAM VB. For example, if license is not set, you might get the following message:

virtual-blade 1 start

wave474# virtual-blade 1 start
WARNING: Virtual-Blade License is not available.
Please, purchase and configure the license.
wave474#

In this case, you might have a license already installed but not active. To find out, use the show license command.

show license

wave474# show license

There are no active licenses configured.
The following list of licenses is available in this release for configuration:
Enterprise
Video
Virtual-Blade
Please, use "license add <LicenseName>" CLI command to enter
the license you purchased already.
wave474#

To activate the VB license, you must activate the Enterprise license, then activate the VB license.

license add Enterprise

wave474# license add Enterprise
WARNING: There is an enabled accelerator in the system, but accelerator doesn't optimize 
the traffic yet. It takes about 2 minutes to start the traffic optimization after the 
license is activated.

license add Virtual-Blade

wave474# license add Virtual-Blade
Note: Please, execute the command
"#virtual-blade .... start" to run Virtual Blades.
WARNING: There is an enabled accelerator in the system, but accelerator doesn't optimize 
the traffic yet. It takes about 2 minutes to start the traffic optimization after the 
license is activated.

Updating the NAM Image

This section describes how to update the Cisco NAM Virtual Blade image.


Step 1 Session into NAM from the WAE with the following command:

virtual-blade 1 session

Step 2 Login to the NAM and reboot the NAM using the command:

reboot

Step 3 Wait for the GRUB menu to display (Figure 8-1), then choose the Helper image menu item.

Figure 8-1 GRUB Menu

Step 4 After the Helper image boots, wait for the boothelper menu to display.

=====================================================

Cisco Systems, Inc.
Network Analysis Module (NAM) helper utility
Version 4.1(1)

-----
Main menu
1 - Download application image and write to HDD
2 - Download application image and reformat HDD
3 - Install application image from CD
4 - Display software versions
5 - Reset application image CLI passwords to default
6 - Change file transfer method (currently ftp/http)
7 - Send Ping
n - Configure network
h - Exit and shutdown Services Engine

Selection [1234567nh]: 

Step 5 If networking is not setup, use option n to set up networking.

If networking is already set up, continue with Step 6.

Step 6 Choose option 1 to download the Cisco NAM VB application image and write to the hard disk.

Step 7 Provide the FTP URL of the new software image. FTP is the default protocol used by the boothelper.

Step 8 After the new image is installed, shutdown the Cisco NAM VB using option h.

Step 9 When the WAE prompt returns, stop and start the Cisco NAM VB:

virtual-blade 1 stop

virtual-blade 1 start

Unable To session Into the NAM Virtual Blade

This section describes how to clear the Cisco NAM VB. If the virtual-blade session is in use, you might not be able to start a new session.

virtual-blade 1 session

WAVE-274# virtual-blade 1 session
Session already in use

virtual-blade 1 session clear

WAVE-274# virtual-blade 1 session clear
WAVE-274#

There are times when you might not be able to session into the NAM even when the session is not in use. You might not be able to enter the reboot command to get to the boothelper menu. In cases like this, restore the Virtual Blade boot parameter to boot from cd-rom.

virtual-blade 1 stop

conf t

virtual-blade 1 boot from cd-rom

end

virtual-blade 1 start

virtual-blade 1 session

After you have downloaded the new application image, set the Virtual Blade boot parameter back to boot from disk.

conf t

virtual-blade 1 boot from disk

end
