Release Note for Cisco ACNS Software, Release 5.5.7

OL-13139-01

Open Caveats in Software Version 5.5.7

Miscellaneous Open Caveats

• CSCdy82311

Symptom: Content cannot be acquired using strong authentication from secure origin servers that

use certificates from nonstandard certificate authorities (CAs). If strong authentication was chosen

for content acquisitions from such a site, the acquirer error statistics will contain a 401

(Unauthorized) error code, and the acquirer error log contains the following error message:

Strong Cert Authentication rejects certificate due to error:

ssl error code

Condition: This problem occurs if the origin server uses a certificate that is not known as a standard

certificate to the ACNS software acquirer. For content acquisition from secure sites over HTTPS

using strong authentication, only sites with certificates from standard certificate authorities are

supported.

With strong authentication, if any errors occur during certificate verification by the ACNS acquirer,

then content from that site will not be acquired. With weak authentication, certain errors (for

example, a certificate has expired, certificate is not yet valid, and a subject issuer mismatch has

occurred) are allowed during certificate verification.

Workaround: Use one of these workarounds:

–

Use weak authentication.

–

On the secure server, use a certificate that was generated by one of the standard certificate

authorities. Refer to the certificate list in the Cisco ACNS Software Upgrade and Maintenance

Guide,Release 5.x document to determine which CA certificate to install on your origin servers.

Note that the certificate list differs based on the version of the ACNS software.

Symptom: When a Content Engine model CE-565 is attached to a Storage Array SA-7 device, if the

cache file system (cfs) partition is allocated a large portion of the disk space (approximately 160 GB

or greater), and a combined streaming and caching workload is used, then a lower HTTP

performance is observed.

Condition: This problem occurs when the CE-565 has Windows Media Technologies (WMT)

enabled, a combined streaming and caching workload is used, and the Content Engine is attached to

an SA-7 device. The Storage Array device is used for the cache file system (cfs).

Workaround: Allocate less space to the cfs if a Storage Array is attached to the Content Engine.

• CSCed68727

Symptom: The Content Distribution Manager only checks if coverage zone files refer to invalid

Content Engines after there is a fresh import. When there is a configuration change that causes

already imported coverage zone files to refer to invalid Content Engines, the Content Distribution

Manager does not check or display the correct error message until the next fresh import.

Condition: This problem occurs if there is a coverage zone configuration change that causes

already-imported coverage zone files to refer to invalid Content Engines.

Workaround: Whenever the hostname of a Content Engine is changed or the Content Engine is

removed from the network, the current information about the device has to be updated in the

corresponding coverage zone file or files.
