Additional Disk Space on ACNS-VB
To procure additional free disk space on an ACNS-VB, follow these steps:
Note This procedure to procure additional disk space will result in a loss of all previous data, including configuration and cached data.
Step 1 Download the 5.5.21 rescue-cdrom.iso image.
Step 2 Stop the ACNS-VB in WAAS by using the following command:
WAE# virtual blade vb_number stop 0
Step 3 After the session stops, change the boot cd-image disk image location to the 5.5.21 iso image by using the following commands:
WAE(config)# virtual-blade vb_number
WAE(config-vb)# boot cd-image disk /local1/vbs/rescue-cdrom.iso
Step 4 Change the boot option of the virtual blade to cd-rom by using the following commands:
WAE(config)# virtual-blade vb_number
WAE(config-vb)# boot from cd-rom
Step 5 Start the virtual blade by using the following command:
WAE# virtual-blade vb_number start
Step 6 Install ACNS 5.5.21. Follow the installation procedure described in the Cisco ACNS Software Upgrade and Maintenance Guide. This guide is available at the following location:
Step 7 After the ACNS installation is complete, stop the virtual blade session by using the following command:
WAE# virtual-blade vb_number stop 0
Step 8 After the session stops, change the boot option of the virtual blade to disk by using the following commands:
WAE(config)# virtual-blade vb_number
WAE(config-vb)# boot from disk
Step 9 Start the virtual blade and check the new disk space when ACNS-VB starts. Additional disk space will now be available.
Hardware Platforms Supported in the ACNS Software
Table 1 shows the hardware platforms supported in each ACNS software release. An "X" indicates that the software supports the hardware models listed in that row.
Note The ACNS 5.4.3 release is the required minimum software release for the WAE-512 and WAE-612 appliances. The ACNS 5.3.3 release is the required minimum software release for the WAE-511, WAE-611, and WAE-7326 appliances. The ACNS 5.5.13 release is the required minimum software release for ACNS-VB running on WAAS virtual blade.
Software Component Versions Supported in the ACNS Software
Table 2 describes the integrated SmartFilter and Websense versions that are supported in the ACNS software.
Table 2 Component Versions Supported in the ACNS Software
ACNS Software Release SmartFilter Version Supported Websense Version Supported
1 The integrated Websense Enterprise software Version 5.5 in the ACNS software requires a minimum of 512 MB of RAM. We recommend that you upgrade the RAM on your device to 512 MB or greater, or move your integrated Websense server to another device that has at least 512 MB of RAM. When additional Websense components are enabled (such as the Network Agent), the ACNS software requires a minimum of 1 GB of RAM.
The following software component restrictions apply to the NME-WAE-502:
•On-box SmartFilter is not supported on the NME-WAE-502 running ACNS version 5.5.7 and later.
Off-box SmartFilter is supported on the NME-WAE-502 running ACNS version 5.5.7 and later.
•On-box Websense is not supported on the NME-WAE-502 running ACNS version 5.5.7 and later.
Off-box Websense is not supported on the NME-WAE-502 running ACNS versions 5.5.7 and 5.5.9. Off-box Websense is supported in ACNS version 5.5.11 and later.
Performance is optimal when Websense Enterprise Manager, the Websense Policy Server, and all other Websense components are situated in the same LAN. If all components are not in the same LAN, you may experience communication latency between Websense Enterprise Manager and other components. A significant increase in latency may lead to a communication failure.
Software Version 5.5.21 Resolved Caveats
This section lists the resolved caveats in the ACNS 5.5.21 release.
•CSCse68072—Counters in the HTTP performance display a maximum value of 4294967.255. When the show statistics http performance CLI is executed, the counters display huge values in the Max Latency column. This occurs when the system clock is set to a date that is earlier or later than the current system date.
Workaround: Execute the CLI clear stat http all to display fresh performance values.
•CSCtj08761—The size of one of the internal file systems for ACNS -VB is 8GB. In such a case, when the disk size allocated to an ACNS VB is small, the ACNS key functionality (Pre-positioning) does not get the required space.
•CSCtj35482—Cannot reinstall ACNS-VB on a WAAS virtual blade using a rescue CD image.
Workaround: Delete the entire ACNS-VB configuration in WAAS and reconfigure using the rescue CD image to reinstall.
