Specify the Host Whose NTP Server We Talk To
The ntphost command specifies the name of the NTP server to which server queries are sent.
This can be a domain name or an IP address. The default is localhost (the local server).
To change the
NTP server for the switch, enter the ntphost command as shown:
ntphost <address>
where <address> is the either the domain name or IP address of the NTP server. For example,
to configure the switch to use an NTP server with an IP address of 1.1.1.4, enter:
ntphost 1.1.1.4
To view the current NTP server used by the switch, enter the ntphost command at the prompt
with no address. A message similar to the following is shown:
current host is 1.1.1.4
Specify a Password to Use for Authenticated Requests
The ntppasswd command allows you to specify a password that must be entered when
making configuration requests. The password must correspond to the key configured for use
by the NTP server.
To specify a password:
1. Enter the
ntppasswd command at the system prompt. A prompt displays asking for the
Key ID number for the server, as shown:
Keyid:
Enter the key ID number for the server (as specified in the key file) and press <return>.
2. The following prompt appears requesting a password, as shown:
Password:
Enter the new password. This password is now required before making a configuration
request of the server.
Set Key ID to Use for Authenticated Requests
The ntpkeyid command allows you to specify a key number to be used to authenticate config-
uration requests. This must correspond to the key number the server has been configured to
use in the key file.
To set a new key
ID, enter the ntpkeyid command as shown:
ntpkeyid <value>
where <value> is the new key ID number. For example, to set the key ID to 2, you would
enter the following:
ntpkeyid 2
To view the currently configured key ID, enter the ntpkeyid command at the prompt and press
<return>. A message similar to the following is shown:
keyid is 2
