# Setting up Redis external attribute caching in the UI

## Before you begin

To successfully assign an external Redis attribute cache to the Policy Decision Service, you must set **PDP Mode** to **embedded**.

## Steps

1. On the **Configuration** page of the PingAuthorize administrative console, go to **Authorization and Policies > External Attribute Caches**.

2. Select your desired Redis mode in the **New External Attribute Cache** list.

   |   | Alternatively, you can use the controls next to the **External Attribute Cache** list to create, edit, or remove external Redis caches:- Click the [icon: plus, set=fa]icon to create a new external attribute cache.

   - Click the [icon: pencil, set=fa]icon to edit the configuration of the selected attribute cache.

   - Click **X** to remove the attribute cache from the Policy Decision Service and revert the PDP to an in-memory attribute cache. |
