Conﬁguring WEP Parameters

WEP has both line and circuit interface parameters. WEP parameters have default

values. You can edit those values to customize WEP for your network.

Enabling Encryption

The WEP Enable parameter defaults to Enable when you select WEP from the

Protocols menu. Both the WEP Enable parameter and the Frame Relay or PPP

Enable parameter must be set to Enable for WEP to function.

Selecting Encryption Strength

Encryption is available in two versions, regular and strong. The standard router

software includes encryption that uses regular encryption, that is, 40-bit keys. We

also offer a strong encryption option that uses 56-bit keys. Strong encryption is

generally available only in the United States and Canada.

Select the encryption strength that is appropriate for your network. Note that you

can select both encryption strengths. This option enables a system that has 56-bit

encryption strength to support secure links with either 40-bit and 56-bit strength

encryption s

ites. If you select both, WEP uses 56-bit encryption if both sides of

the link can support it

Setting Change Rates for the TEK

The TEK changes depending on the values of the TEK Change Time and TEK

Change Bytes parameters.
