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.
