Info

Configuring NTP Configuring Network Time Protocol (NTP) Using Authentication Authentication is used to encrypt the NTP messages sent between the client and server. The NTP server and the NTP client must both have a text file containing the public and secret keys. (This file should be obtained from the server administrator. For more information on the authentication file, see “Authentication” on page 11-8.) Once both the client and server share a common MD5 encryption key, the MD5 key identification for the NTP server must be specified on and labeled as trusted on the client side. The Omniswitch will use MD5 authentication. Key files reside in /flash/network/ntp.keys. In order to generate a key file, access to a Solaris/Unix environment is required. Also required is the ntpkeygen utility in Unix to generate the key file. Setting the Key ID for the NTP Server Enabling authentication requires the following steps: 1 Make sure the key file is located in the /networking directory of the switch. This file must contain the key for the server that provides the switch with its timestamp information. 2 Make sure the key file with the NTP server’s MD5 key is loaded into the switch memory by issuing the ntp key load command, as shown: -> ntp key load 3 Set the server authentication key identification number using the ntp server command with the key keyword. This key identification number must be the one the server uses for MD5 encryption. For example, to specify key identification number 2 for an NTP server with an IP address of 1.1.1.1, enter: -> ntp server 1.1.1.1 key 2 4 Specify the key identification set above as trusted. A key that has been labeled as trusted is ready for use in the authentication process. To set a key identification to be trusted, enter the ntp key command with the key identification number and trusted keyword. For example, to set key ID 5 to trusted status, enter the following: -> ntp key 5 trusted Untrusted keys, even if they are in the switch memory and match an NTP server, will not authenticate NTP messages. 5 A key can be set to untrusted status by using the ntp key command with the untrusted keyword. For example, to set key ID 5 to untrusted status, enter the following: -> ntp key 5 untrusted page 11-12 OmniSwitch AOS Release 8 Switch Management Guide May 2014
Configuring Network Time Protocol (NTP) Verifying NTP Configuration Verifying NTP Configuration To display information about the NTP client, use the show commands listed in the following table: show ntp status show ntp server client-list show ntp client server-list show ntp keys Displays information about the current client NTP configuration. Displays the basic server information for a specific NTP server or a list of NTP servers. Displays a list of the servers with which the NTP client synchronizes. Displays information about all authentication keys. For more information about the resulting displays from these commands, see the “NTP Commands” chapter in the OmniSwitch AOS Release 8 CLI Reference Guide. Examples of the show ntp client, show ntp server status, and show ntp client server-list command outputs are given in the section “NTP Quick Steps” on page 11-3.
