Remove One or More Key ID's from the Trusted List

The trusted list in the key file is a list of all keys that are considered authentic and uncompro-
mised. Messages from an

NTP

entity using one of these keys are accepted and acted upon. It

is possible to remove a key from the trusted list.

To remove a key ID from the trusted list, enter the

ntpdkey

command as shown:

ntpdkey <value>

where

<value>

is the new key

ID

to be remove from the trusted list. For example, to remove

key

ID

5 from the trusted list, enter the following:

ntpdkey 5

A brief message is displayed confirming the operation.

Note

Removing a key

ID

using the

ntpdkey

command

removes the key from the working version of the key
file in the switch’s

RAM

. If you reset the switch or re-

initialize

NTP

, the removed key is reinstated.
