Usage Guidelines
•
Authentication keys are stored in a key file and loaded into memory when the switch boots. The keys
loaded into memory are not trusted until this command is used.The location of the file containing set of
generated authentication keys is /flash/network/ntp.keys.
•
Once the keys are loaded into software (on boot up of the switch), they must be activated by being
labeled as trusted. A trusted key will authenticate with a server that requires authentication as long as
the key matches the server key.
•
New keys must be added manually to the key file. A newly added key will not be loaded into the
switch software until the
•
An authentication key is composed of a 32-bit integer and 32-byte string of characters. The integer
format is hexadecimal. For an NTP message to be authenticated the NTP client authentication key
must match the key configured at the NTP server. This means the authentication keys must be distrib-
uted in advance of configuring the NTP client. If authentication is disabled but authentication key is
present, the association will still be unauthenticated.
•
By default all keys read from the ntp.conf key file are untrusted therefore keys must be set to 'trusted'
status to allow NTP to use the key for authentication.
Examples
-> ntp key 5 trusted
-> ntp key 2 untrusted
