# Authenticator PAE Configuration

Port > Configure > Authenticator PAE Configuration

The Port Access Entity (PAE) that performs authentication before allowing access to services available through a particular port is referred to as the authenticator PAE. In the authenticator role, the PAE is responsible for communicating with the supplicant and forwarding the information received from the supplicant to a suitable authentication server, in order to verify the credentials and determine the appropriate authorization state. Keep in mind that the functionality of the authenticator PAE is independent of the actual authentication method. It merely acts as an intermediary for the authentication exchange.

The following information is displayed:

- Authenticator State (dot1xAuthPaeState)
- Backend Authenticator State (dot1xAuthBackendAuthState)
- Admin Controlled Directions (dot1xAuthAdminControlledDirections)
- Operational Controlled Directions (dot1xAuthOperControlledDirections)
- Controlled Port Status (dot1xAuthAuthControlledPortStatus)
- Controlled Port Control (dot1xAuthAuthControlledPortControl)
- Quiet Period (dot1xAuthQuietPeriod)
- Tx Period (dot1xAuthTxPeriod)
- Supplicant Timeout (dot1xAuthSuppTimeout)
- Server Timeout (dot1xAuthServerTimeout)
- Maximum Requests (dot1xAuthMaxReq)
- Re Authentication Timeout (dot1xAuthReAuthPeriod)
- Re Authentication Enabled (dot1xAuthReAuthEnabled)
- Key Tx Enabled (dot1xAuthKeyTxEnabled)
- Last EAPOL Frame Version (dot1xAuthLastEapolFrameVersion)
- Last EAPOL Frame Source (dot1xAuthLastEapolFrameSource)
