Selecting the Traffic Handling Mode

ETEP Configuration

The ETEP has three options for processing packets:

●Encrypt all packets

●Discard all packets

●Pass all packets in the clear

Under normal operation, the ETEP is configured to encrypt all traffic that is exchanged between two peer appliances. This is the ETEP’s default mode of operation. Other methods of traffic handling are used for debugging and troubleshooting. The traffic handling setting persists through a reboot.

How the ETEP Encrypts and Authenticates Traffic

When operating as a Layer 2 encryptor in a point-to-point policy, the ETEP’s encapsulation mode authenticates the encrypted frame’s Ethernet payload. The ETEP uses the AES algorithm with 256-bit keys to encrypt the Ethernet payload. The HMAC-SHA-1 authentication algorithm provides the data origin authentication and data integrity.

To encrypt traffic, ETEPs must establish security associations (SAs). A security association defines the processing to be done on a specific packet. It associates security services and a key with the traffic to be protected and the remote peer with whom secured traffic is being exchanged. The SA is a unidirectional secure tunnel through which data passes between the two appliances. Each secure connection has two SAs, one for each direction. SAs are identified by a value called an SPI.

In point-to-point Layer 2 configurations the SAs are automatically negotiated using IKE. Timeout values force the IKE protocol to renegotiate the IKE Phase 1 and Phase 2 keys periodically. The ETEP can uses a preshared key for authentication in IKE negotiations.

When encrypting traffic the ETEP uses the values shown in Table 107 and Table 108. These values are hard-coded and cannot be modified by the user.
