+- Supported on Basic, Standard,Premium, Enterprise and Enterprise Flash tiered Azure Cache for Redis instances.
 - By using [Azure Private Link](../private-link/private-link-overview.md), you can connect to an Azure Cache instance from your virtual network via a private endpoint. The endpoint is assigned a private IP address in a subnet within the virtual network. With this private link, cache instances are available from both within the VNet and publicly.  
 - Once a private endpoint is created, access to the public network can be restricted through the `publicNetworkAccess` flag. This flag is set to `Disabled` by default, which will only allow private link access. You can set the value to `Enabled` or `Disabled` with a PATCH request. For more information, see [Azure Cache for Redis with Azure Private Link](cache-private-link.md).
 - All external cache dependencies won't affect the VNet's NSG rules.
