Changing an NPK on a Router

To change the router NPK value, follow the procedure in the section, “Entering an

NPK on a Router” on page 3-9.

Changing an NPK in the MIB

To change the NPK value in the MIB:

At the Technician Interface, enter:

ksession

You enter the secure shell, which prompts you for the password.

Enter the password.

The prompt changes to

SSHELL

Enter:

ktranslate

<old_NPK_value>

The MIB now has the same NPK as the router.

Save the configuration file.

Changing LTSSs

You should change LTSSs periodically. To change LTSSs, create new ones using

the WEP Key Manager tool as described in the section “

Creating NPKs and

LTSSs” on page 3-7.

Creating TEKs

The router stores its TEK seed in nonvolatile memory. WEP uses and manages the

TEK to encrypt data. Your only task is to create a seed for the RNG that generates

TEKs.

Note:

These instructions assume that you have connected a PC or UNIX

computer directly to the console port of the router. For instructions on

connecting a computer to the router console port, refer to the installation guide

that came with your router.
