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
where 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.

The ntpauth command allows you to look at the statistics of the authentication routine. These
statistics consist of counters for various functions of the authentication code.
To view the statistics of the authentication code, enter the ntpauth command at the system
prompt. A screen similar to the following is shown:
time since reset: 0
key lookups: 0
keys not found: 0
uncached keys: 0
