Support for 7371

ACNS 5.5.27 release supports WAE -7371 hardware. The device modes supported are CE and CDM.

Additional Disk Space on ACNS-VB

ACNS-VB 5.5.21 and later versions reserve less disk space for system use, leaving more disk space for other purposes. This change is not applied during a regular upgrade process. To procure additional disk space, a complete installation needs to be performed.

For steps to procure additional free disk space on an ACNS-VB, please refer to ACNS 5.5.21 release notes.

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 5.5.27 Resolved and Open Caveats

The following sections list the resolved and open caveats in the ACNS 5.5.27 release.

Software Version 5.5.27 Resolved Caveats

Software Version 5.5.27 Open Caveats

Software Version 5.5.27 Resolved Caveats

This section lists the resolved caveats in the ACNS 5.5.27 release:

CSCtx32411—Server response with status 301 redirect containing Cache-Control directives that dictate not to store, is cached by CE and delivered for subsequent client request.

Workaround: Disable caching of a problematic URL using a rule.

CSCtx86471— Sysreport CLI accepts and generates report for future dates.

CSCtz88848—Current open SSL version in ACNS is vulnerable for CVE-2012-2110 and CVE-2012-2131, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service.

CSCua16982—Response for prepositioned content with range request is missing Content-Type header.

CSCua22817—Current version of Linux kernel in ACNS is vulnerable to CVE-2005-3181, which may lead to a memory leak that allows attackers to cause a denial of service.

CSCua48057—ACNS Listing API getObjectById is not returning the ContentIP address in a standard format. Sometimes the address is shown with just the IP_Address and sometimes the address is shown as HOSTNAME#IP_Address.

CSCua52525—Playing a corrupt WMV file with huge packet length results in high CPU and memory usage, while trying to allot memory to hold this packet.

CSCub15270—SNMP error messages are seen in syslog while booting the CE.

CSCub28618—When Multicast is disabled in the Sender or Receiver in the multicast A&D process, the CE shows a minor alarm and the CDM GUI shows a major alarm. Need to increase the severity of svcnomcastenable alarm in CE.

Software Version 5.5.27 Open Caveats

This section lists the open caveats in the ACNS 5.5.27 release.

CSCtz72352—Under certain unknown scenarios, icap sockets get into CONNECTING state but are unable to complete. After timeout, cache process follows error handling.

Workaround: A script can be provided to monitor and restart the icap process automatically to handle such situations.

CSCua78707—During NTLM negotiation, sometimes the HTTP connection is closed by the CE and the client browser displays the unexpected password prompt.

Workaround: None

CSCub65561—ACNS is vulnerable to Java's Floating-Point issue (CVE-2010-4476).

Workaround: None

CSCtc05567—Rescue CD may not reconfigure controller, on platforms with hardware RAID and at least one logical drive setup.

Workaround: Use the RAID setup utility during POST to delete all logical drive.

CSCtz76320—When more than one router and CE are in the farm and when one paricular interface is going down, the CE with lower ip address gets 100% bucket allotment instead of sharing the load among the CEs.

Workaround: Restart wccp service in any one of the interface(s).

CSCub25431—Priority 0 not recognised by Gigabit 2/0 interface in standby group.

Workaround: Use priority number other than zero for Gigabit 2/0 interface.

CSCub31326—Enabling DNS while standby is configured as primary interface fails and throws error.

Workaround: Configure gigabit interface as primary interface and enable dns service.
