ntp authentication key

Adds the same key ID/hash value pair that already exists on an NTP server to the appliance. After a key ID/value pair is added, the key ID must mapped to that NTP server using the command ntp server <server> authentication .

Syntax

There are two ways to configure the key ID and hash value you obtained from the NTP server.

Prompt Method

The prompt method is recommended, because it accepts all special characters and masks the hash value as you enter it. With this method, press Enter after <type> and then enter <value> at the prompt.

hostname (config) # ntp authentication key <number> hash <type>
Key: <value>

Single-Line Method

With this method, enter all parameters on the same line.

hostname (config) # ntp authentication key <number> hash <type> <value>

Parameters

number

The key ID, which is an integer from 1-16.

type

The type of authentication key: md5 or sha1.

value

The key's hash value.

Example

The following example uses the prompt method to add a key ID/value pair to an appliance.

hostname (config) # ntp authentication key 6 hash md5 
Key: ********************************
hostname (config) # show ntp authentication configured
NTP enabled: yes
NTP Authentication enabled: yes
NTP Key Number 6
  Type: md5
  Key: ********
