Fixed In:
12.0.0, 11.6.0 HF5

Opened: Feb 26, 2015

Severity: 2-Critical


In 11.5.x and earlier versions it was possible to have a SPDY profile with the following combination of settings: activate-mode always, and protocol-versions { spdy3 spdy2 http1.1 }. In 11.6.0 this was changed to allow only a single protocol-version in conjunction with 'activation-mode always'.


This might cause a failure when upgrading from prior versions to 11.6.0 or later.


A SPDY profile with activate-mode always and multiple protocol versions for protocol-versions.


Before upgrading make sure all SPDY profiles with 'activation-mode always' only have a single 'protocol-versions' value set.

Fix Information

A SPDY profile with 'activation-mode always' and multiple 'protocol-versions' no longer causes an upgrade to fail. Instead upgrade changes the profile such that the 'protocol-versions' field only contains the highest SPDY protocol version that was listed before the upgrade.
