Enabling Encryption
117386-A Rev. A 3-19
TEK Change Bytes
The TEK Change Bytes parameter sets the number of bytes between changes in
the value of the TEK.
TEK Change Time
The TEK Change Time parameter sets the number of seconds between changes in
the value of the TEK.
Disabling Encryption
Remember that the Frame Relay or PPP Encrypt Enable parameter and the WEP
line and circuit interface parameters must all be set to Enable for encryption to
work. This does not mean that you can temporarily disable encryption on a line or
interface by setting any of these parameters to Disable.
If you enable encryption for the line and circuit, but not for a protocol, and an
LTSS exists, data does not travel over the network.
Deleting Encryption from an Interface
To delete encryption from an interface on which it is currently configured:
1. In the Configuration Manager window, select Circuits > Edit Circuits.
The Circuit List window opens.
2. Click on Edit.
The Circuit Definition window opens.
3. Select Protocols > Add | Delete.
The Select Protocols window opens.
4. Deselect WEP and click on OK.
Encryption is no longer operating on the interface.
