Licensing Issues

---

Note Cisco NAM VSB 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 VSB license is not set, you will not be able to start the NAM VSB. For example, if the 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 VSB license, you must activate the Enterprise license, then activate the VSB 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.

Unable to Session into the NAM Virtual Services Blade

This section describes how to clear the Cisco NAM VSB. 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 VSB 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 VSB boot parameter back to boot from disk.

conf t

virtual-blade 1 boot from disk

end
