Enforcing CDN version supported by node
A parameter was added since build 5.2.341 to enforce CDN version supported by this node
| Code Block | ||
|---|---|---|
| ||
cdn_force_version=2.0 |
By default, CDN 2.0 is set. The node dynamically sets CDN version to 2.1 or 2.2 depending on role (Transcoder) and ACL settings.
To make Edge node to detect Transcoder node faster, it is recommended to enforce Transcoder node CDN version to 2.1
| Code Block | ||
|---|---|---|
| ||
cdn_force_version=2.1 |
or to 2.2 if ACL rules are used in CDN
| Code Block | ||
|---|---|---|

cdn_force_version=2.2 |
