Configuring NTP (CLI)

Use this procedure to configure NTP.

Go to configuration services ntp and enter authkey to edit authorizations.

hostname:configuration services ntp> authkey
hostname:configuration services ntp authkey>

From this context, new keys can be added with the create command.

hostname:configuration services ntp authkey> create
hostname:configuration services ntp authkey-000 (uncommitted)> get
                        keyno = (unset)
                         type = (unset)
                          key = (unset)
hostname:configuration services ntp authkey-000 (uncommitted)> set keyno=1
                        keyno = 1 (uncommitted)
hostname:configuration services ntp authkey-000 (uncommitted)> set type=A 
                         type = SHA1 (uncommitted)
hostname:configuration services ntp authkey-000 (uncommitted)> set key=coconuts
                          key = (set) (uncommitted)
hostname:configuration services ntp authkey-000 (uncommitted)> commit
hostname:configuration services ntp authkey>

To associate authentication keys with servers via the CLI, the serverkeys property should be set to a list of values in which each value is a key to be associated with the corresponding server in the servers property.
If a server does not use authentication, the corresponding server key should be set to 0. For example, use the following commands to use the key created earlier to authenticate the servers server1 and server2:
```
hostname:configuration services ntp> set servers=server1,server2
                      servers = server1,server2 (uncommitted)
hostname:configuration services ntp> set serverkeys=1,1
                   serverkeys = 1,1 (uncommitted)
hostname:configuration services ntp> commit
hostname:configuration services ntp>
```
To associate authentication keys with servers, set the serverkeys property to a list of values in which each value is a key to be associated with the corresponding server in the servers property.

                   serverkeys = 1,1 (uncommitted)
hostname:configuration services ntp> commit
hostname:configuration services ntp>
```

Use the following commands to authenticate the server server1 with key 1, server2 with key 2, and server3 with key 3.

hostname:configuration services ntp> set servers=server1,server2,server3
                      servers = server1,server2,server3 (uncommitted)
hostname:configuration services ntp> set serverkeys=1,2,3
                   serverkeys = 1,2,3 (uncommitted)
hostname:configuration services ntp> commit
hostname:configuration services ntp>

Use the following commands to authenticate the servers server1 and server2 with key 1, and to additionally have an unauthenticated NTP server (server3).

hostname:configuration services ntp> set servers=server1,server2,server3
                      servers = server1,server2,server3 (uncommitted)
hostname:configuration services ntp> set serverkeys=1,1,0
                   serverkeys = 1,1,0 (uncommitted)
hostname:configuration services ntp> commit
hostname:configuration services ntp>
