Release Notes for Cisco ACNS Software, Release 5.5.31
July 23, 2013
Note The most current Cisco documentation for released products is available on Cisco.com.
This release note contains information about the Cisco Application and Content Networking System (ACNS) software version 5.5.31.
This release note contains the following topics:
Virtual ACNS Support
Virtual ACNS(vACNS) support in ACNS 5.5.31 allows you to quickly deploy vACNS instances on VMWare ESXi hosts such as the Cisco Unified Computing System (UCS). The ACNS Content Distribution Manager can manage vACNS instances in the same graphical interface through which it manages other ACNS devices in the network. In addition, the virtual Content Distribution Manager can manage both physical and vACNS instances. A separate vACNS license is required for vACNS support. See the Cisco Virtual ACNS Software Installation and Configuration Guide for details.
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 ACNS 5.5.31 is the required minimum software release for the virtual ACNS appliances. ACNS 5.5.31 supports all the hardware models along with Virtual Content Engines. VCExxx is supported on UCS -B and UCS-C models. 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. ACNS 5.5.27 is the required minimum software release for WAE-7371.
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.
