SNTP: Viewing, Selecting, and Configuring

Associating a Key with an SNTP Server

After a key is configured, it must be associated with a specific server.

Syntax: [no] sntp server priority <1-3> <ip-address ipv6-address> <version-num> [key-id <1-4,294,967,295>]

Configures a key-idto be associated with a specific server. The key itself must already be configured on the switch.

The no version of the command disassociates the key from the server. This does not remove the authentication key.

Default: No key is associated with any server by default.

priority: Specifies the order in which the configured servers are polled for getting the time. Value is between 1 and 3.

<version-num>:Specifies the SNTP software version to use, and is assigned on a per-server basis. The version setting is backwards-compatible. For example, using version 3 means that the switch accepts versions 1 through 3.

Default: 3; range: 1 - 7.

key-id:Optional command. The key identifier (range 1­ 4,294,967,295) sent in the SNTP packet. This key-idwill be associated with the SNTP server specified in the command.

ProCurve(config)# sntp server priority 1 10.10.19.5 2 key-id 55

Figure 9-13. Example of Associating a Key-Id with a Specific ServerEnabling SNTP Client Authentication

The sntp authentication command enables SNTP client authentication on the switch. If SNTP authentication is not enabled, SNTP packets are not authen­ ticated.

Syntax: [no] sntp authentication

Enables the SNTP client authentication.

The no version of the command disables authentication.

Default: SNTP client authentication is disabled by default.
