Description

Issue, Impact and workaround:

  • For NetScaler VPX, CPX, BLX: The starting minimum bandwidth is 20 Mbps. In all cases, the value must always be in multiples of 10 Mbps. Bandwidth allocation in non-multiples of 10 Mbps is considered invalid. 
  • While Console service now auto-heals this situation (by rounding off the bandwidth to the nearest higher multiple of 10 Mbps), it is a known issue with NetScaler licensed using Console on-premises release 14.1-73.x or earlier that can cause your NetScaler instances to become unlicensed. This known issue, depending on your NetScaler version and build, could either hide silently and cause NetScaler to go unlicensed on the next reboot or it could put your NetScaler in grace and eventually cause it to become unlicensed. The issues have been release noted with NSCONFIG-14995 and NSHELP-44344 in the following release notes:

 

  • 14.1-73.33: https://docs.netscaler.com/en-us/updates?product=NetScaler%2520ADC%2520%28includes%2520NetScaler%2520Gateway%29&version=14.1&build=73.33
  • 13.1-64.22: https://docs.netscaler.com/en-us/updates?product=NetScaler%2520ADC%2520%28includes%2520NetScaler%2520Gateway%29&version=13.1&build=64.22
  • Given this issue, it is important that you review the bandwidth checked out by all your NetScaler VPX/BLX/CPX instances (including VPX on SDX) and take action as soon as possible to correct or update the bandwidth value to a multiple of 10 Mbps
  • This issue is also documented in LAS for NetScaler landing page FAQ section: https://docs.netscaler.com/en-us/citrix-adc/current-release/licensing/las-for-netscaler.html#in-case-of-las-with-pooled-or-flexed-license-type-what-is-a-valid-bandwidth-to-checkoutallocate-to-a-netscaler-instance-is-there-any-known-issue-that-i-must-be-aware-of
