Entering a key identification that is already in use effectively edits that key to the new
value. Further note: The key list can have up to 16 MD5 keys.
6.3.5
Back in the
MD5 Edit Menu:
you can select
Delete a key
or
Delete all keys
to remove
one or all MD5 keys. These menus operate in a similar fashion as the edit and add
menus and they are protected from accidental entry by yes or no menu confirmations.
Further, you will not be allowed to enter these menus if there are no MD5 keys.
6.3.6
When you finish with the MD5 key tasks, you may leave the MD5 menus by successively
pressing
Back one menu
or by pressing the STATUS key. Note: If you press the
STATUS key, make sure that you have confirmed your last operation in the
Yes
or
No
menu appropriate for the operation, otherwise your last operation will have no effect.

SERIAL MD5 KEY CONFIGURATION
6.4.1
The easiest method to maintain NTP MD5 keys is through the serial interface. This is
due to the fact that MD5 keys are alpha/numeric strings and the keypad interface does
not allow easy entry of alpha characters. You may add, delete and view the MD5 keys
using the serial interface.
6.4.2
To view a particular NTP MD5 key type:
F36 MV:x
Where x is the key identification number ranging from 1 to 4294967295.
6.4.3
The unit will respond with:
F36 key ID = x, key = ValueOfMD5KeyString
6.4.4
To view the next NTP MD5 Key type:
F36 MV
6.4.5
The unit will respond with:
F36 key ID = (x+1), key = ValueOfMD5KeyString
Where (x+1) is the next key identification in numerical order from the last serial
command that reference a key identification. Note: After booting,: the key viewed
will be the lowest numbered key identification. If the previous key viewed was at the
end of the key identification list it will wrap back to the first key identification.
6.4.6
To add a NTP MD5 key type:
F36 MS:x ValueOfMD5KeyString
Where x is the key identification number ranging from 1 to 4294967295 and
ValueOfMD5KeyString is the MD5 ASCII string key ranging from 1 to 31 characters.
Note: It is best to limit the string to alpha/numeric characters only. If other
characters are desired, then the restrictions the remote NTP client program places
on the string must be considered.
6.4.7
The unit will respond with:
OK
