Specifying an SNTP server 2

The authentication-keyoption allows you to configure an authentication key for communication with the SNTP server. When the authentication key is configured for an SNTP client, it is used only for an SNTP unicast client. You must assign a unique server <key-ID> and pre-share <key-string>. The <key-ID> and pre-share <key-string>are used together to create the MD5 checksum. The MD5 checksum is used for authentication for request and reply messages with the SNTP server. The <key-ID> is the symmetric key shared with the upstream server, and accepts values from 1 to 4,294,967,295. The <key-string> is the authentication string itself, and can take up to 16 characters. If the <key-string> variable consists of only numerical characters, you must enclose the numerical characters in double quotes.

Modification of the authentication key fields is not supported. To change the key ID or key string, remove the time server using the no sntp server... command, then reconfigure the server with the new key.

By default, the Brocade device polls its SNTP server every 30 minutes (1800 seconds). To configure the Brocade device to poll for clock updates from a SNTP server every 15 minutes, enter the following.

Brocade(config)# sntp poll-interval 900

Syntax: [no] sntp poll-interval <16-131072>

To display information about SNTP associations, enter the show sntp associations command.

The following table describes the information displayed by the show sntp associations command.

TABLE 5 Output from the show sntp associations command

Field	Description
(leading character)	One or both of the following:
	* Synchronized to this peer
	~ Peer is statically configured
address	IP address of the peer
ref clock	IP address of the peer reference clock, or the reference ID of the
	external clock source if the peer is stratum 1.
	Examples of external clock source IDs: GPS, CDMA, WWV (Ft.Collins US
	Radio 2.5, 5, 10, 15 MHz), CESM (calibrated Cesium clock), etc.
st	NTP stratum level of the peer
when	Amount of time since the last NTP packet was received from the peer. A
	negative number indicates the system has never received any
	synchronization message from the specified server.
poll	The poll interval of the peer relative to the server.
delay	The total delay time in milliseconds along the path to the root clock.
disp	The dispersion of the root path in milliseconds.
