Addressed Issues

Hostname does not support all previously supported special characters

When editing the hostname customer receives invalid parameter value error.

This issue has been fixed.

• Special charactersnow supported are:
  ~`!@#$%^*()_+-=[]{}|;:,./?

• unsupported special characters:
  &<>'“

Supported special characters in the hostname as ~`!@#$%^*()_+-=[]{}|;:,./? should be used with caution.

The special characters can create the following issues:

• DNS job: Users cannot create a job configuration if the hostname contains the character """" and cannot modify the hostname of any device if it includes """".

• Users cannot add special characters in the hostname as a reflector for session management automatically by default name. User must modify the default name to remove the special character.

• Users are unable to create objects and virtualize the performance monitoring data on Skylight performance analytics if hostname contains the following special characters:
  ~!@#$%^*()_+-=[]{}|;:,./?
  • Unable to create circuits and virtualize performance monitoring data for device hostname containing """" on the Skylight SLA Portal.

Operational Considerations

Important Notes

• The Skylight element: LX firmware is delivered in a consolidated file prefixed by “ACC”, e.g. ACC_7.X_YYYY.afl. This file contains the firmware for the GT, GX , LX and LT Performance Element products. It cannot be used with any other product.
• IMPORTANT: Prior to upgrading the firmware on a unit where the History Buckets feature is enabled, certain precautions may need to be taken to prevent a loss of history data during the upgrade.
• After upgrading to 7.9.1 or 7.9.2, the SCP is no longer able to send files, reporting the following error: Code = 3: URL using bad/illegal format or missing URL. This is due to a syntax change and customer needs to edit the URL after upgrading to 7.9.2 or 7.9.3.
  The URI generic syntax (in RFC 3986) consists of a hierarchical sequence of five components: URI = SCHEME ':' ['//' AUTHORITY] PATH ["?" QUERY] ["#" FRAGMENT]. In this, AUTHORITY = [USER_INFO "@"] HOST [":" PORT]. The AUTHORITY part and the PATH part are isolated by the slash ('/') character if the AUTHORITY exists.
